OPINION

I. INTRODUCTION

Appellant San Bernardino City Professional Firefighters Local 891 (the “Union”) appeals an order from the United State Bankruptcy Court for the Central District of California, Riverside Division, that granted in part and denied in part the City of San Bernardino’s (the “City”) motion to reject a memorandum of understanding between the Union and the City. San Bernardino City Prof'l Firefighters Local 891 v. San Bernardino (In re City of San Bernardino), No. 6:12-bk-28006, ECF No. 1187 (Bankr.GD.Cal. Sept. 19, 2014) (the “Rejection Order”) 1 The Union raises six arguments on appeal. The Union’s principle argument is that the City failed to meet the necessary burden of proof for setting aside a collective bargaining agreement as established in N.L.R.B. v. Bildisco & Bildisco, 465 U.S. 513 , 104 S.Ct. 1188 , 79 L.Ed.2d 482 (1984). For the reasons discussed below, the Court AFFIRMS the Bankruptcy Court’s order in full.

*477 II. FACTUAL AND PROCEDURAL BACKGROUND

A. Original Labor Agreement and Attempts to Reach Extension

Over a decade ago, the City and the Union entered into a labor agreement titled “Fire Safety Employees Memorandum of Understanding — January 1, 2003 to June 30, 2009” (the “MOU”). (ER 160-214, 655.) 2 The MOU contains an “evergreen clause” which states: “Upon expiration of the MOU and until a new MOU has been negotiated between the Union and the City, all articles in this MOU shall remain in full effect, unless otherwise stated in this MOU.” (Id. at 198.) In June 2009, the parties extended the MOU’s expiration date to June 30, 2010.

On April 16, 2012, the City’s director of human resources sent a letter to the Union’s counsel asking to meet and confer to determine if the parties could reach an agreement on a successor MOU. (Id. at 742.) On April 25, 2012, the City sent another e-mail to the Union seeking to schedule MOU negotiations. (Id. at 744-45.) On June 18, 2012, Bob Heitzman sent an e-mail to the Union indicating that he was hired by the City to assist with labor relations. (Id. at 747.) Heitzman noted that it was imperative that the City and the Union begin meeting regarding the “extension of the current compensation or other alternatives.” (Id.) The Union responded seeking clarification on the scope of discussions and the effect of a separate lawsuit between the Union and the City. (Id. at 749-50.) Heitzman replied that it would “take some time” to respond to all of the Union’s questions, but he indicated that his request was to meet and confer for a successor MOU. (Id. at 752-54.) The parties agreed to meet on July 17, 2012. (Id. at 752.) On July 16, 2012, Heitzman postponed the meeting. (Id.)

B. Bankruptcy Petition and Initial Financial Changes

The City’s financial situation deteriorated quickly in the summer of 2012. The City ran out of cash to pay its creditors and employees, and had a projected budget deficit of $45.8 million. - (Id. at 82-84, 891.) Personnel costs alone were projected to exceed all of the City’s General Fund, revenue. (Id. at 84.) On August 1, 2012, the City filed a voluntary bankruptcy petition under Chapter 9, Title 11 of the United States Code. (Id. at 1-8.) Five days later, the San Bernardino City Council (the “City Council”) passed a resolution deferring certain employment payments to include cash-outs and sell-backs of unused leave time. (SER 298 — 99.)

Shortly thereafter, the City contacted the Union to discuss modifications to the MOU. (ER 150, 534-42, 546-51, 557-64.) On September 10, 2012, the Union’s labor negotiator, Corey Glave, responded that unless the City was willing to reverse or modify the City Council’s cost-cutting measures, a meeting between the two parties was “really just a waste of time, money and resources for both the City and the Union.” (Id. at 547.) On September 18, 2012, the City notified the Union that it hired a new attorney to handle labor negotiations and that it would like to begin MOU negotiations with the Union. (Id. at 761.) The parties met on September 26, *478 2012, but did not conduct any MOU negotiations. (Id.) After the City offered six dates for negotiations, Glave reiterated, inter alia, that recession of the cost-saving measures was a pre-condition to negotiations. (Id. at 57, 555-56; SER 571-57.)

C. Substantive Changes to Labor Agreements and Mediation

On November 26, 2012, the City Council passed a “Pendency Plan” which set forth a series of expenditure reductions and required the City to negotiate contract modifications with the Union and the City’s six other labor unions. (ER 56-60.) Five unions reached agreements with the City to modify their employment agreements. (Id. at 147-49, 484-89.) The Union and the City did not initially reach an agreement.

During January 2013, the City and the Union engaged’ in a confidential, and ultimately unsuccessful, mediation session before the Honorable Scott Clarkson. (Id. at 658, 3530.) The parties met January 11, 17, and 23. (Id.) On February 1, 2013, the City Council, relying on its fiscal emergency status, passed a resolution that imposed “interim terms and conditions of employment” for the Union. (Id. at 658.)

D. The Rejection Motion and Subsequent Discovery

On March 4, 2013, the City filed a motion with the Bankruptcy Court seeking authorization to reject the MOU (the “Rejection Motion”). (Id. at 9-30.) The Rejection Motion sought to set aside the MOU and nunc pro tunc approval of the City Council’s February 1, 2013 resolution. (Id. at 29, 32-34.)

On March 8, 2013, the Union filed a Motion to Confirm the Termination of the Automatic Stay, or Alternatively, for Relief from Automatic Stay (the “Motion for Relief’). (Id. at 3625-3799.) In its Motion for Relief, the Union sought relief to file an action in a non-bankruptcy forum to challenge the interim employment terms imposed by the City Council’s February 1 resolution. (Id.) On March 21, 2013, the Union filed a timely opposition to the Rejection Motion and raised two evidentiary objections to declarations attached to the City’s Rejection Motion. (Id. at 625, 809-16.)

On April 4, 2013, the Bankruptcy Court held a preliminary hearing on the Rejection Motion. (Id. at 817-85.) At the hearing, the Bankruptcy Court defined discovery limits in connection with the planned depositions of the City’s witnesses, but did not publish a corresponding discovery order. (Id. at 837-78.) Subsequent hearings were scheduled, but were each continued to allow for further discovery. (Id. at 1058-59, 1090-97.) On May 6, 2013, the parties filed a joint report regarding the status of the discovery. (SER 605 — 15.)

The Union, in opposing the Rejection Motion, deposed three witnesses that the City cited and relied upon in its Rejection Motion. (Id. at 777-803, 1001-1310.) The Union claims that the City instructed its key witnesses to not respond to several lines of questioning at the depositions. (ER 1167-1464.) On July 10, 2013, the Union filed a motion to strike the testimony of two of the City’s three witnesses or, in the alternative, to compel further answers to deposition questions. (Id. at 1167-1464.) The line of questioning at issue related to the City’s ability to negotiate consensual modifications to the MOU. The City opposed the motion to strike, and on July 31, 2013, the Bankruptcy Court denied the Union’s motion. (SER 755-959, 970-71;' ER 1465-1540, 1763-69.) The Bankruptcy Court explained that it previously limited the scope of discovery in a manner that justified the City’s witnesses from responding to certain ques *479 tions. (ER 3552-59.) The Bankruptcy Court acknowledged that it did not publish an order limiting the scope of discovery for the Rejection Motion. (Id. at 3560-61.)

The Bankruptcy Court, at the request of the Union, continued the Rejection Motion until it first determined whether the City was eligible for chapter 9 relief. (Id. at 637, 1770-74.) From September 2013 through June 2014, the Rejection Motion was continued to the same dates as the status conferences in the underlying chapter 9 case. (SER 1527-30, 1539, 1542-44, 1463-66, 1574-78, 1587-88, 1590-94.) The Bankruptcy Court continued the hearing dates for the Rejection Motion fifteen separate times.

E. Further Mediation and Meetings

On September 5, 2013, the Bankruptcy Court appointed the Honorable Gregg W. Zive as the Case Mediator and ordered all major creditors, which included the Union, to participate in mediation before Judge Zive. (Id. at 1467-68.) The City and the Union met on three separate occasions prior to mediation to discuss the City’s financial conditions and the City’s cost-cutting proposals: October 2013, December 2013,'and February 2014. (ER 2595.)

On May 23, 2014, the City and the Union met outside of the confidential mediation process, and discussed the proposed budgets for the City and the fire department. (Id. at 2595-96.) On May 27, 2014, the City and the Union attended a mediation session before Judge Zive, and the City made a proposal to the Union regarding changes to the MOU. (Id. at 2596.) This was the first mediation since the failed mediation before Judge Clarkson in January 2013.

On June 19, 2014, the Bankruptcy Court granted the Union’s request for relief from the September 5 mediation order. (Id. at 2152.) After releasing the Union from the mediation order, the Bankruptcy Court set a supplemental briefing schedule and hearing date for the then-still-pending Rejection Motion. (Id. at 2182-88.) On July 18, 2014, the City delivered a proposal to the Union regarding implementation of a fire department budget previously approved by the City Council. (Id. at 2596.) On July 28, 2014, the City and the Union began discussing thirty-one proposed changes to the MOU. (Id. at 2655-2702.) On July 30, 2014, the City sent the Union a revised proposal. (Id. at 2653-2702.) The City and the Union met again on August 13, 2014, August 25, 2014, and September 3, 2014 to discuss the proposed changes to the MOU. (Id. at 2597, 3089-90, 3093-3411.)

F. Adjudication of Rejection Motion

On September 11, 2014, the Bankruptcy Court heard arguments on the Rejection Motion as it applied to the MOU. (Id. at 2356-2491.) On September 19, 2014, the Bankruptcy Court published the Rejection Order. (Id. at 3448-50.) The Rejection Order, while authorizing the City to reject the MOU, specifically declined to provide the City with nunc pro tunc relief relating to the February 1, 2013 City Council resolution or any relief authorizing the implementation of new terms and conditions. (Id.) The City then lodged, at the Bankruptcy Court’s request, proposed findings of fact and conclusions of law. (Id. at 3458-3507, 3800-49.) The Union filed two separate objections and lodged its own proposed findings of fact and conclusions of law. (SER 3006-19, 3485, 3808-26.) After consulting with the California Public Employees Retirement System (“Cal-PERS”), the City lodged a revised findings of fact and conclusions of law, and replied to the Union’s objections. (Id. at 3097-3188, 3238-3467, 3827-66.)

*480 On November 4, 2014, the Bankruptcy-Court published its findings of facts and conclusions of law to support the Rejection Order. (ER 3508-47.) The Bankruptcy Court also published an order rejecting the Union’s evidentiary objections. (SER 2867-79.)

III.STANDARDS OF REVIEW

The Court has jurisdiction pursuant to 28 U.S.C. § 158 (a), and is sitting as a single-judge court of appeal. The traditional appellate review standards apply. The Court reviews the Bankruptcy Court’s conclusions of law de novo and its factual findings for clear error. Salazar v. McDonald (In re Salazar), 430 F.3d 992, 994 (9th Cir.2005). Review under the clearly erroneous standard requires significant deference to the trial court. Ambassador Hotel Co. v. Wei-Chuan Inv., 189 F.3d 1017 , 1024 (9th Cir.1999).

“A mixed question of law and fact occurs when the historical facts are established; the rule of law is undisputed ...; and the issue is whether the facts satisfy the legal rule.” Murray v. Bammer (In re Bammer), 131 F.3d 788, 792 (9th Cir.1997) (citing Pullman-Standard v. Swint, 456 U.S. 273 , 289 n. 19, 102 S.Ct. 1781 , 72 L.Ed.2d 66 (1982)). “Mixed questions presumptively are reviewed ... de novo because they require consideration of legal concepts and the exercise of judgment about the values that animate legal principles.” Id. (citing Boone v. United States, 944 F.2d 1489, 1492 (9th Cir.1991)).

A court’s evidentiary rulings are reviewed for abuse of discretion. Watec Co. v. Liu, 403 F.3d 645 , 650 n. 3 (9th Cir.2005). “To reverse on the basis of an erroneous- evidentiary ruling, [a court] must conclude not only that the bankruptcy court abused its discretion, but also that the error was prejudicial.” Santa Barbara Capital Mgmt. v. Neilson (In re Slat-kin), 525 F.3d 805 , 811 (9th Cir.2008) (internal citations omitted). “A reviewing court should find prejudice only if it concludes that, more probably than not, the lower court’s error tainted the verdict.” McEuin v. Crown Equip. Corp., 328 F.3d 1028, 1032 (9th Cir.2003) (internal quotation marks omitted).

IV.ISSUES ON APPEAL

The Union raises six issues on appeal:

(1) “Did the Bankruptcy Court err in finding the City met its burden of proof on-the element of ‘reasonable efforts to negotiate voluntary modifications to the collective bargaining agreement were made’ under [Bildisco ]?”;

(2) “Did the Bankruptcy Court err in finding that City met its burden of proof when it found the [MOU] was a burden on the City?”;

(3) “Did the Bankruptcy Court err by limiting discovery on the Motion for an Ordeh Authorizing Rejection of the [Union’s] Collective Bargaining Agreement?”;

(4) “Did the Bankruptcy Court err by (a) waiting 18 months to render a decision on the [City’s] Motion for an Order Authorizing Rejection of the [Union’s] Collective Bargaining Agreement, and (b) authorizing further briefing?”;

(5) “Did the Bankruptcy Court err in finding the City can reject the [MOU] under 11 U.S.C. § 365 even though the [MOU] expired under its own terms pre-petition?”; and

(6) “Did the Bankruptcy Court err by issuing an advisory opinion on the ‘practical effect’ of the rejection of the [MOU]?” (Appellant Br. 3-4.)

V.DISCUSSION

The parties do not dispute the applicable law or the factual record for the six issues *481 on appeal. Instead, the Union merely contests the Bankruptcy Court’s application of facts to law and discretionary rulings. As discussed' below, the Court must reject each of the Union’s arguments. The Court will discuss each issue in turn.

A. Issue 1: Reasonable Efforts to Negotiate

The first issue on appeal is whether the City made reasonable efforts to negotiate voluntary modifications to the MOU. This issue involves mixed questions of law and fact and is reviewed de novo. See In re Bammer, 131 F.3d at 792 .

Bankruptcy Code section 365(a) provides that a debtor “may assume or reject any executory contract.” 11 U.S.C. § 365 (a). In Bildisco, the Supreme Court held that the language “executory contract” in section 365(a) includes collective bargaining agreements. Bildisco, 465 U.S. at 521-22 , 104 S.Ct. 1188 . Bildisco instructs that in order for a debtor to reject a collective bargaining agreement under section 365(a), the debtor must show; (1) “reasonable efforts to negotiate a voluntary modification have been made, and are not likely to produce a prompt and satisfactory solution,” (2) the agreement is a burden on the debtor, and (3) the balance of the equities weigh in favor of the rejection. Id. at 526 , 104 S.Ct. 1188 . The debtor bears the burden of establishing that these factors are satisfied. Id.

Chapter 9 of the Bankruptcy Code, which authorizes a municipality to discharge its debt through bankruptcy, incorporates section 365(a). 11 U.S.C. § 901 (a); see also In re City of Vallejo, 403 B.R. 72, 77 (Bankr.E.D.Cal.2009) aff'd in 432 B.R. 262 (E.D.Cal.2010) (“Congress incorporated section 365 into chapter 9 without restricting or limiting its application to collective bargaining agreements.”). “The judicial consensus is that Bildisco controls rejection of collective bargaining agreements in chapter 9 cases.” Ass’n of Retired Employees of the City of Stockton v. Stockton (In re City of Stockton), 478 B.R. 8, 23 (Bankr.E.D.Cal.2012); see also In re City of Vallejo, 432 B.R. at 272 (“The Bankruptcy Court properly concluded that a municipality operating under Chapter 9 may utilize 11 U.S.C. Section 365 to reject a CBA, if the municipality can show that the requirements of Bildis-co are met.”); Orange County Employees Ass’n v. Orange (In re County of Orange), 179 B.R. 177, 183 (Bankr.C.D.Cal.1995) (“Bildisco applies in Chapter 9.”).

The inquiry into whether a municipality made “reasonable efforts to negotiate a voluntary modification” involves the application of case-specific facts to the law.. Here, the parties do not dispute the law or the operative' facts, but instead dispute the Bankruptcy Court’s application. The Bankruptcy Court concluded that the City satisfied Bildisco-by making reasonable efforts to negotiate a modification to the MOU. Rejection Order at 34-37. The Bankruptcy Court reached this conclusion based on the “aggregate” of the following events:

Id. at 35.

The Bankruptcy Court also explained that a prompt and satisfactory solution was not likely because the Union made no concessions to the City’s offers even *482 though the Union was informed that modifications were necessary. Id. at 35-36. The Bankruptcy Court further noted that the lack of meetings was a result of the Union’s “reluctance to engage with the City” and the Union refused to negotiate without first receiving a comprehensive proposal, which is not required under Bil-disco. Id. at 36.

On appeal, the Union makes two arguments regarding the reasonableness of the City’s efforts to negotiate. First, the Union claims that the evidence of reasonable efforts is “scant” and the Bankruptcy Court relied on “innuendo and supposition” stemming from the confidential mediation sessions. (Appellant Br. 16.) The Union argues: “The fact that the parties attended mediation does not sufficiently establish reasonable efforts to negotiate voluntary modifications to the MOU were made; the -‘reasonableness’ of the City’s efforts to ‘negotiate’ cannot be ascertained by speculating on matters that occurred in a confidential mediation session.” (Id.)

The Union’s argument is legally unsupported and lazy. As an initial matter, the mediation sessions were not the only occasions in which the parties met. The parties began discussions before the City even filed its voluntary petition and met on numerous occasions outside the mediation process. Communications between the parties began as early as April 2012. In fact, it was the Union’s representative Glave that refused to meet in the fall 2014 despite the City’s efforts to find a workable time. (ER 57, 555-56; SER 571-57.) The City’s willingness to meet and compromise, and the Union’s stubbornness, is quite apparent from the wealth of e-mail traffic between the parties. (Id.) The Union’s claim that the evidence regarding reasonable efforts is “scant” is a misrepresentation of the evidence.

Furthermore, the Union wants this Court to believe that because the mediation sessions were confidential, the City can therefore not prove that they acted reasonably during the mediation. The Union cites no law for this proposition. The City and the Union mediated before Judge Clarkson for at least three days, and before Judge Zive at least once. The City showed up on time, sent the appropriate negotiators, and spent hours upon hours talking with Union representatives. The Court does not need to .know the precise talking points of those discussions to conclude that such conduct was reasonable. There is no legal requirement that the Court pour over the contents of a mediation to determine if negotiations were reasonable. In fact, Bildisco only requires “reasonable efforts to negotiate a voluntary modification” without any mention of judicial review of all matters discussed during negotiations. Bildisco, 465 U.S. at 526 , 104 S.Ct. 1188 . The Union’s reading of Bildisco would render all unsuccessful, confidential mediations per se unreasonable. Bildisco does not require the parties to reach a resolution and recognizes that even the lack of a “prompt” resolution can justify rejection of a collective bargaining agreement. Id. The parties mediated on at least four occasions, met outside the mediation process on at least three occasions, and exchanged a host of e-mails and phone calls regarding meeting times and modifications. The Union cannot rely on the confidentiality of the mediation to claim the City failed to carry its burden. The Court rejects the Union’s over-zealous reading of Bildisco .

The Union’s second argument regarding the • reasonableness of negotiations ’ is equally as vapid. The Union argues: “the evidentiary record demonstrates the City made no real effort to make consensual changes to the MOU or negotiate a new MOU.” (Appellant Br. 16.) In making this *483 claim, the Union cherry picks the facts it wants while ignoring the entirety of the record. The Union also fails to cite any authority involving similar facts. Essentially, the Union wants the Court to take its word. The Union is correct that six months passed between the imposition of the interim terms of employment and the mediation sessions, but it is equally true that Union representatives refused to meet, the City kept the Union informed on the financial conditions and employment proposals, and the City struck deals with five of the other labor unions. The record is replete with e-mails from the City seeking times to meet with the Union. The legal standard is reasonableness — not “no real effort” — and the City’s extensive outreach to communicate and meet with the Union, while in the midst of a financial collapse, unquestionably satisfies Bildisco .

The District Court in In re City of Vallejo affirmed a bankruptcy court’s “reasonableness” findings on grounds that the bankruptcy court “ordered the parties to judicially supervised settlement talks” and the record indicated “almost two years of negotiations between the City and its unions.” 432 B.R. at 275 . The efforts in this case, also spanning nearly two years and involving judicially supervised settlement talks, were at least as expansive as those in In re City of Vallejo. There is no authority to suggest otherwise. The Bankruptcy Court found that the City acted reasonably, and based on its own review of the record, this Court agrees. The Union’s “no real effort” argument is rejected.

In passing, the Union complains that the Bankruptcy Court “did not reference” the Union’s proposed findings of fact in the Rejection Order. (Id. at 17.) The Union fails to identify any of the alleged facts that the Bankruptcy Court ignored and how those facts would impact the case. The Bankruptcy Court is the finder of fact. It has the duty to weigh the evidence and make factual conclusions. The Bankruptcy Court did its job. If the Union wants to challenge the Bankruptcy Court’s factual conclusions, it should have made a “clearly erroneous” argument. There is no legal principle that requires a court to “reference” the proposed findings of fact from both parties. The Court therefore rejects this cursory argument.

The Court concludes that the City made reasonable efforts to make voluntary modifications to the MOU, thus satisfying the standard from Bildisco . The Bankruptcy Court’s conclusion on this issue is affirmed.

B. Issue 2: MOU a Burden on the City

The second issue on appeal relates to the City’s claim that the MOU was a financial burden to reorganization. This is also a mixed question of law and fact reviewed de novo. See In re Bammer, 131 F.3d at 792 .

As explained swpra, the second element in Bildisco requires the debtor to prove that the collective bargaining agreement is a burden on the debtor’s ability to reorganize. Bildisco, 465 U.S. at 525-26 , 104 S.Ct. 1188 . The Bankruptcy Court found that the “City submitted substantial evidence that the MOU was a burden on the City’s ability to recover from its insolvency.” Rejection Order at 37. The Bankruptcy Court noted the costs of unnecessary overtime, the costs of paying CalPERS premiums, and the Union’s refusal to agree, to any modification that required more pension contribution from the Union’s members. Id. at 37-38. The Bankruptcy Court also noted the City’s dire financial situation and lack of funds to provide necessary services to its citizens. Id.

*484 On appeal, the Union claims that the City failed to prove it was financially burdened by focusing on the testimony of the City’s financial expert, Michael Bush. The Union argues that Mr. Bush “did not have an accurate understanding of the finances” and “could not testify as to what the overall cost savings to the City would be if the [Union] contract was rejected.” (Appellant Br. 18.) The Union further argues-that a “cost to the City is not the equivalent of a ‘burden’ on the City under Bildis-co.” (Id.) The Union claims that Bush admitted that he did not factor the budget surplus and “cost savings for concessions of other employee groups,” and therefore the City failed to carry its burden of proof. (Id.)

The Unions arguments are flawed for several reasons. First, it is clear that the Union does not understand how the bankruptcy process works. On October 16, 2013, the Bankruptcy Court issued an order confirming the City’s eligibility to file for chapter 9 bankruptcy. (SER 1483-1514.) In that order, the Bankruptcy Court ruled that “[t]he uncontroverted facts establish that the City is insolvent. The City was unable to pay its forthcoming obligations when the resolutions were passed and faced a cash deficit of $45.9 million for fiscal year 2012-2013. This issue is uncontested.” (SER 1500.) It was also undisputed that the City’s personnel costs alone surpassed the entire General Fund. (ER 89.) The costs of public safety — specifically the fire and police departments — accounted for 72 percent of the City’s annual budget. (Id. at 83-84.) Despite these uncontested facts, the Union has the audacity to now claim that there is not enough evidence that the MOU was a burden. Any financial obligation for an insolvent debtor is a burden, which is why a debtor would seek bankruptcy protection in the first place.

Additionally, the Court is appalled that the Union would suggest that the cuts to other labor unions must be considered before its own MOU is deemed a burden. There is no law anywhere that allows a creditor to sandbag the bankruptcy process and then claim its debt is not a burden because other creditors already took cuts. The Union is not entitled, preferential treatment because it held out the longest and refused to negotiate. This sly attempt to discredit the worth of the other public sector labor unions is astounding.

Second, the Union waived any argument it had to challenge Bush’ testimony. During the proceedings before the Bankruptcy Court, the Union did not offer its own expert evidence regarding the MOU’s burden and expressly waived an opportunity for an evidentiary hearing and cross-examination of Bush. (ER 2366; 2374, 2382, 2408, 3509.) In its Rejection Order, the Bankruptcy Court explains that the “City’s evidence on the financial burden of the contract was entirely unrebutted by any admissible evidence presented by the [Union], who chose to not present any expert testimony to counter the testimony of Michael Bush.” Rejection Motion at 2. By not challenging the financial burden of the MOU before the Bankruptcy Court, the Union waived any right to do so on appeal. In re Mercury Interactive Corp. Sec. Litig., 618 F.3d 988, 992 (9th Cir.2010) (holding arguments not raised in the bankruptcy court are waived on appeal). In presenting this meritless argument, the Union even fails to cite a single page from the record or a single authority.

In passing, the Union also claims that the Bankruptcy Court’s findings regarding the burden of the MOU were flawed due to several evidentiary errors. First, the Union argues that the Bankruptcy Court relied on evidence “submitted after the initial hearing on the-Rejection *485 Motion” and “[t]hese items should not have been admitted by the Court because they were untimely.” (Appellant Br. 19.) The Union claims that the “Bankruptcy Court erred when it relied upon these untimely pleadings.” (Id.) Unsurprisingly, the Union cites zero authority for this claim. This argument is baseless. The Union did not object to the Bankruptcy Court’s consideration of this evidence until after it entered the Rejection Order, and thus this argument is waived on appeal. See Mercury Interactive Corp., 618 F.3d at 992 . Furthermore, evidentiary rulings are reviewed under an abuse of discretion standard and the appellant must show prejudice. McEuin, 328 F.3d at 1032 . Lower courts are afforded “broad discretion” in evidentiary rulings. Harper v. Los Angeles, 533 F.3d 1010, 1030 (9th Cir.2008). There is no rule that prohibits evidentiary submissions following a hearing and there is no viable argument that the Bankruptcy Court committed any abuse of direction. The proceedings below were a fluid situation, and the Bankruptcy Court took the steps it felt were appropriate to reach the correct result. Affording the Bankruptcy Court broad discretion to consider filings after a posted hearing date, the Court finds no abuse of discretion. The Court therefore rejects the Union’s argument.

The Court concludes that the MOU was a financial burden to the City. The Bankruptcy Court’s conclusion on this issue is affirmed.

C. Issue 3: Discovery Limits

The third issue on appeal relates to the Bankruptcy Court’s April 4, 2013 discovery order related to the Rejection Motion. At the April 4 hearing, the Union sought permission from the Bankruptcy Court to depose the City’s negotiators who were cited in the City’s Rejection Motion. (Appellant-Br. 19.) The Union “sought information relating to the City’s ability to negotiate consensual modifications to the MOU” after the City disclosed a proposed budget. (Id. at 21-22.) As noted in the factual background section, supra, the Bankruptcy Court issued an oral order setting parameters for the deposition request. The Bankruptcy Court limited the depositions of the City’s negotiators — Diana Leibrich and Linda Daube — to the source and scope of their authority to negotiate voluntary modifications to the MOU. (See ECF No. 560 at 17:11-15, 33:12-22, 55:3-8, 60:14-16.) On June 10, 2013, the Union filed a “Motion to Strike Evidence, or in the Alternative, to Compel Deposition Responses.” (ECF No. 686.) The motion claimed that Leibrich and Daube refused to answer the following questions: “(1) the nature and extent of alleged negotiations between the City and the [Union]; (2) whether the City’s negotiators had authority to conduct good faith negotiations with the [Union] as opposed to merely proposing a predetermined ultimatum.” (Id. at 2.)

At a hearing on July 31, 2013, the Bankruptcy Court denied the Union’s motion. (ECF No. 720.) The Bankruptcy Court described the Union’s motion as “unrealistic” and “backwards.” (Id. at 5.) In explaining why it limited the depositions to only the authority to negotiate, the Bankruptcy Court explained:

(ER 1475-76.)

Here, the Union argues that “the Bankruptcy Court abused its discretion when it limited the [Union’s] depositions of the City’s witnesses.” (Appellant Br. 19.) The Union claims that Federal Rule of Civil Procedure 26 authorizes broad discovery and a federal court may only limit discovery where justice requires the protection of a party from “annoyance, embarrassment, oppression, or undue burden or expense.” (Id. at 20-21 [quoting Oppenheimer Fund v. Sanders, 437 U.S. 340, 351 , 98 S.Ct. 2380 , 57 L.Ed.2d 253 (1978) ].) According to the Union, “[o]ther than saving the City the cost of responding to discovery, there was no other basis for limiting discovery,” and “there was no evidence that the costs would unduly burden the City; the Bankruptcy Court simply assumed significant costs would be incurred and elected to sua sponte limit discovery.” (Id. at 21.) The Union further argues that “[t]o ascertain the City’s ability to negotiate anything more than a take-it-or-leave-it offer, the [Union] questioned the City’s negotiators on the subject” and “[i]f responses were provided, it is likely that the discovery requests would have revealed whether or not the City could actually make reasonable efforts to negotiate consensual changes above its budgetary bottom-line.” (Id. at 22.)

All of the Union’s arguments are merit-less. First, the Bankruptcy Court’s discovery limitations had nothing to do with costs to the City. The Bankruptcy Court does not even mention the costs to the City. Instead, it correctly found that the deposition of the City’s negotiators was not another opportunity for the Union to rehash issues from the confidential bargaining table. Discovery was limited to the scope of the negotiators’ authority and it appears that those questions were answered. (ER 1307-12, 1314-18, 1321, 1324-34,1338-40.)

Furthermore, a trial court “is vested with broad discretion to permit or deny discovery, and a decision to deny discovery will not be disturbed except upon the clearest showing that the denial of discovery results in actual and substantial prejudice to the complaining litigant.” Laub v. U.S. Dep’t of Interior, 342 F.3d 1080, 1084 (9th Cir.2003) (internal quotation marks and citations omitted). The Union fails to make a “clearest showing” of “substantial prejudice.” The Bankruptcy Court succinctly explains that the confidential and privileged information from negotiations was not relevant in its determination of whether the City made reasonable efforts to negotiate under Bildisco . The Bankruptcy Court determined that it did not need all of the specifics of the negotiations to decide the issue. Both parties engaged in the same negotiation and both already knew exactly what occurred during.that process. Deposing the negotiators on those same negotiations is simply not necessary or relevant. The Union’s argument, which is unsupported by any precedent, is soundly rejected. The *487 Union fails to make any showing of prejudice.

In passing, the Union complains that the Bankruptcy Court failed to publish a formal discovery order and this failure “created[d] havoc in discovery.” (Appellant Br. 22.) The Union never once requested a written order, never availed itself of other remedies before the Bankruptcy Court, and never raised this objection below. This torpid argument is waived. See Mercury Interactive Corp., 618 F.3d at 992 .

The Court concludes that the Bankruptcy Court did not abuse its discretion in limiting discovery.

D. Issue 4: Delay in Issuing Order

The fourth issue on appeal focuses on the length of time between the filing of the Rejection Motion and its final disposition. The Rejection Motion was filed on March 8, 2013, and the Bankruptcy Court issued the Rejection Order on September 19, 2014. The Union challenges the Bankruptcy Court’s docket management, and such challenge is reviewed for an abuse of discretion. Preminger v. Peake, 552 F.3d 757 , 769 n. 11 (9th Cir.2008).

Section 365 does not impose any deadlines for court rulings rejecting execu-tory contracts. 11 U.S.C. § 365 . The Court cannot find, and the Union fails to identify, any rule or statute that mandates a bankruptcy court to issue any ruling within a certain time period. Relying on no case law or statutory authority, the Union argues that it was prejudiced by the delay because it “resulted in a second round of briefing whereby the City was given another opportunity to brief the Rejection Motion and was given a right to reply to any opposition of the [Union] to the supplement.” (Appellant Br. 26.) There are no allegations that the City was provided with opportunities that the Union did not have. Both parties were treated equally and the Court strains to see any logic behind the Union’s claim that more briefing is bad. Ironically, the Union even requested the Bankruptcy Court to continue the hearing on the Rejection Motion. (ER 637.) The proceedings below involved no less than seven different unions, dozens of creditors, millions of dollars of debt, and several confidential mediations. The Bankruptcy Court did not abuse its discretion by allowing the complex factual record to develop and both parties additional briefing opportunities. There is simply no rule preventing the Bankruptcy Court from authorizing further briefing and evidence, and the Court rejects any invitation to meddle with a lower court’s docket management. The Bankruptcy Court did not abuse its discretion and the Court, therefore, rejects .this legally unsupported claim.

The Union further argues that the delay in ruling on the Rejection Motion left the interim terms of employment — previously imposed on February 1, 2013 — in effect for an “unprecedented” and “protracted” period. (Appellant Br. 26.) The Union acknowledges that “Bildisco provides a temporary safe-haven for [the] City while its Rejection Motion was pending,” but the interim terms of employment “became something more than ‘interim’ ” because the Bankruptcy Court did not immediately rule on the Rejection Motion. (Id. at 27.)

Once again, the Union makes' an argument without any support in the law. The Union does not even bother to analogize examples from other areas of law, but instead relies on hollow supposition. The Union’s claim that the Bankruptcy Court’s delay was “unprecedented” and “protracted” is unfounded, and its claim that the interim terms were “something more than ‘interim’” is unreasonable. Bildisco explicitly authorizes the imposed' interim *488 terms in this case, and the Court is not inclined to create an arbitrary rule regarding the outer limit of “interim.” There was no error of law or abuse of discretion. This argument is rejected in full.

The Court concludes that the Bankruptcy Court did not abuse its discretion in ruling on the Rejection Motion.

E. Issue 5: Expiration Before Rejection

The fifth issue on appeal concerns the expiration of the MOU. Most of the Union’s arguments on appeal concern the City’s ability to reject the MOU. The Union also offers an argument in the alternative: “The Bankruptcy Court erred when it found the MOU could be rejected even though it expired pre-petition.” (Appellant Br. 23.) ■

The Union argues that the MOU was “extinguish[ed]” in 2011. The MOU contains an evergreen clause which states that the MOU’s terms and conditions remain in full effect after the MOU expires unless a new MOU is negotiated. (ER 198.) The MOU expired naturally on June 30, 2010 without a new agreement. The parties do not dispute that the MOU initially remained in effect. On appeal, the Union claims that the MOU was “extinguish[ed]” on February 22, 2011 when the City Council passed Resolution 2011-33. (Appellant Br. 23.) Resolution 2011-33 unilaterally imposed certain employment conditions on the Union’s members. The Union claims that the MOU “lost all characteristics of a contract upon the codification of the terms and conditions in Resolution 2011-33 because the terms and conditions of employment were not consensual.” (Id. at 24.) The Union further argues that “the Court’s factual finding that the MOU continued on as a result of an ‘evergreen’ is faulty; the MOU eease[d] to exist upon the implementation of Resolution 2011-33 and any ‘evergreen’ clause that may have existed in the MOU was extinguished. If not, then the 2011-33 Resolution would be void in its entirety.” (Id.)

This argument is meritless for a number of reasons. First, the Union waived this argument by not raising it below. The Union never once argued to the Bankruptcy Court that Resolution 2011-33 extinguished the entire MOU, and in fact, the Union continually argued that the MOU was still in effect. The Union’s opposition to the Rejection Motion repeatedly acknowledged that the MOU was in effect (ER 632-60), and the Union’s proposed statement of facts also acknowledges that the MOU was in effect (SER 3817; see also ER 2757-3048, SER 2006-19, 3458-3807, 3808-26). The Union even requested that the Bankruptcy Court conclude that “the evergreen clause in the MOU is enforceable, and the MOU is subject to rejection under Section 365(a).” (Id.) The Union’s new claim that “[Resolution 2011-33], and not the MOU, were the terms and conditions of employment that existed on the Petition Date,” contradicts the first half of its appellate brief as well as every representation it made to the Bankruptcy Court. Accordingly, the Union’s argument is waived. See Mercury Interactive Corp., 618 F.3d at 992 .

Second, and notwithstanding the waiver issue, the Union’s argument is meritless. The evergreen clause states that the MOU remained in effect “until a new MOU has been negotiated.” (ER 198.) The Union’s claim that the MOU was “extinguish[ed]” is factually and legally unsupported. Resolution 2011-33 contains no language that suggests that the entire MOU is void or that the evergreen clause is no longer applicable. The Union conveniently makes no mention of the terms in Resolution 2011-33 or why those terms would extinguish the entire MOU, but both parties *489 concede that some of those terms came directly from the MOU and others were thrown out by a California Superior Court. (ER 792-94.) In addition to lacking any factual basis for this claim, there is no authority to support the Union’s position. No legal authority supports the Union’s argument that an entire MOU is nullified as a result of a city council employment resolution. The parties are bound by the plain language in the MOU’s evergreen clause. The Court rejects this argument in full.

F. Issue 6: Advisory Opinion

The sixth issue on appeal relates to the scope of the Bankruptcy Court’s Rejection Order. The Union argues that the Bankruptcy Court held that the “ ‘practical effect’ of rejection of the MOU is the right afforded to the City to implement new terms and conditions of employment” and “[sjection 365 does not provide any authority for the Bankruptcy Court” to make this conclusion. (Appellant Br. 27-28.) These conclusions, according to the Union, “constitute an impermissible advisory opinion.” (Id. at 28.)

The statement from the Bankruptcy Court at issue is as follows: “For that reason, where a court approves rejection of a collective bargaining agreement under Section 365(a), the practical effect of rejection is that the debtor is permitted to implement new terms and conditions of employment, notwithstanding that there may be applicable labor laws that permit such changes only after the parties have negotiated to impasse.” (ER 3540.) This statement from the Bankruptcy Court is nothing more than dicta. Contrary to the Union’s claim, the Bankruptcy Court’s statement did not authorize the imposition of new employment terms. The statement merely recognizes the proper legal standards going foiward. There is no basis in the law for this Court to overturn an order from a bankruptcy court solely on dicta. The statement from the Bankruptcy Court is an accurate statement of the law and does nothing to change the relationship between the parties. The Court rejects this argument in full.

VI. CONCLUSION

The Court hereby AFFIRMS the Bankruptcy Court’s Order Granting in Part and Denying in Part City of San Bernardino’s Motion Authorizing Rejection of Collective Bargaining Agreement with San Bernardi-no City Professional Firefighters. In re City of San Bernardino, No. 6:12-bk-28006, ECF No. 1187. The Clerk of the Court shall close this case.

IT IS SO ORDERED.

. The Rejection Order is a two-page document that merely grants in part the Rejection Motion. On November 7, 2014, the Bankruptcy Court published the “Findings of Fact and Conclusions of Law Regarding Order Granting in Part and Denying in Part City of.San Bernardino's Motion Authorizing Rejection of Collective Bargaining Agreement with San Bernardino City Professional Firefighters." In re City of San Bernardino, No. 6:12-bk-28006, ECF No. 1262 (Bankr.C.D.Cal. Nov. 4, 2014) (ER 3508-47). The Rejection Order is the appealable final order, while the Bankruptcy Court's November 4, 2014 Order provides the justifications and is the scrutinized order on appeal. Accordingly, both orders are treated as a single entity and are jointly referred to as the "Rejection Order."

. Due to the voluminous record below, the parties submitted their own excerpts. While managing two “records” is not ideal, the Court does not identify any conflict between the submissions and the parties raise no objections. Citations to the "Excerpts of the „ Record” or "ER” denote the excerpts submitted by the Union. (ECF Nos. 13-23.) Citations to the "Supplemental Excerpts of the Recórd” or "SER” denote the excerpts submitted by the City. (ECF Nos. 29-42.) The parties do not dispute any facts on appeal.
