The City of Hemet and individual police officers appeal a jury verdict for Benigni in his section 1983 suit alleging that police officers harassed his business to such an extent that he was finally forced to sell it at a loss. We affirm.

BACKGROUND

Benigni opened the Silver Fox Restaurant and Bar in November 1983. He filed suit on December 7, 1984, alleging that Hemet police officers constantly harassed his business and customers by: (1) performing bar checks on a daily basis; (2) following customers leaving the Silver Fox and occasionally arresting them for drunk driving and other violations; (3) issuing parking tickets to staff and customers; (4) parking across the street and “staking out” his customers, employees and family members; (5) stopping cars for traffic violations in the vicinity of the Silver Fox after “herding” or “red lighting” them into that area; and (6) investigating an alleged bomb threat on December 8, 1984, the day after Benigni filed suit. Benigni claimed the officers made five or six bar checks a night inside the business and that they shined flashlights in customers’ faces, checked identifications of people obviously over 21, and searched drawers behind the bar. Be-nigni contends this harassment eventually forced him to sell at a loss in March 1986.

Benigni’s section 1983 suit alleged violations of his first amendment right of association, his fourth amendment right against unreasonable search and seizure, and his fourteenth amendment rights to due process and equal protection. A jury awarded Benigni compensatory damages of $285,000 against the City, compensatory damages of $7,500 and punitive damages of $7,500 against Chief of Police Roger Miller, and compensatory damages of $2,500 and punitive damages of $3,000 against police officer Jesse Pease. The jury found in favor of officer Jernigan and he appeals the district court’s denial of attorney fees. The City argues that the verdict is not supported by substantial evidence and that the case was improperly submitted to the jury on non-applicable legal theories.

DISCUSSION

I. THEORIES OF LIABILITY

As a preliminary matter we must consider whether the City has preserved its legal challenges for review on this appeal. The City has not met the requirement of Fed.R.Civ.P. 51, which says “[n]o party may assign as error the giving or the failure to give an instruction unless he objects thereto before the jury retires to consider its verdict, stating distinctly the matter to which he objects and the grounds of his objection.” This court has held that Rule 51 is satisfied even where the plaintiff does not object to instructions when plaintiff proposes alternative instructions and the district court is aware that plaintiff does not agree with the court’s instructions. Martinelli v. City of Beaumont, 820 F.2d 1491, 1493-94 (9th Cir.1987); Brown v. Avemco Investment Corp., 603 F.2d 1367, 1371 (9th Cir.1979).

In this case the City proposed alternative jury instructions but the record indicates that the trial court was not made aware of any specific concern with the proposed instructions. See Martinelli, 820 F.2d at 1493 ; Robert’s Waikiki U-Drive v. Budget Rent-A-Car, 732 F.2d 1403, 1410 (9th Cir.1984). No specific objection or argument focused the issue before the court or gave it an opportunity to modify the instruction to incorporate the elements of the City’s proposed instructions. See Budget Rent-A-Car, 732 F.2d at 1410 . The purpose of Rule 51 is to give the trial court the opportunity to correct potential error, id., and the trial court had no such opportunity here. Thus we do not agree with the City that this is a situation in which we should review instructions in the absence of a clear objection.

The Supreme Court’s recent decision in City of St. Louis v. Praprotnik, — U.S. -, 108 S.Ct. 915, 922 , 99 L.Ed.2d 107 (1988), does not mandate a different result. In Praprotnik the Court held that in a section 1983 case legal issues are preserved for review even in the absence of objection to jury instructions when the petitioner has moved for summary judgment and directed verdict, advancing the same legal argument being advocated in the reviewing court. Id. In this case, the appellants moved for summary judgment, the individual appellants moved for a directed verdict on the ground of their asserted immunity, and all appellants moved for judgment NOV or for new trial. The mem-oranda in support of the motions for summary judgment and judgment NOV argued that Benigni’s claims that his federal rights were infringed were unsupported by the evidence. These motions thus are not suf ficient to raise objection to the jury instructions or to preserve any objections for review- on appeal. Thus we will not address the adequacy of the district court’s instructions.

II. SUFFICIENCY OF THE EVIDENCE

We will consider whether there is evidence supporting the verdict sufficient to justify submitting the various theories of liability to the jury. First, we note that our review is “extraordinarily deferential” because of the City’s failure to move for a directed verdict on the liability issues at the close of all 'the evidence. Herrington v. Sonoma County, 834 F.2d 1488 , 1501 (9th Cir.1987). “It is thoroughly established that the sufficiency of the evidence is not reviewable on appeal unless a motion for a directed verdict was made in trial court.” United States v. 33.5 Acres of Land, 789 F.2d 1396, 1400 (9th Cir.1986) (quoting Trans World Airlines, Inc. v. Shirley, 295 F.2d 678, 678-79 (9th Cir.1961)); C. Wright & A. Miller, 9 Federal Practice and Procedure § 2536 at 593 (1971).

Because the City is precluded from challenging the sufficiency of the evidence, our “ ‘inquiry is limited to whether there was any evidence to support the jury’s verdict, irrespective of its sufficiency, or whether plain error was committed which, if not noticed, would result in a “manifest miscarriage of justice.” ’ ” Herrington, 834 F.2d at 1500 (quoting Shipman v. Central Gulf Lines, Inc., 709 F.2d 383, 386 (5th Cir.1983) (quoting Coughlin v. Capitol Cement Co., 571 F.2d 290, 297 (5th Cir.1978))). We review liability findings to determine whether there is an absolute lack of evidence supporting the verdict. Id.

(1) First Amendment Claim

Recently the Supreme Court reiterated that its cases have protected associational freedom in two senses: (1) holding that the Constitution protects against interference with an individual’s choice to enter into and maintain certain intimate or private relationships; and (2) holding that the Constitution protects the freedom of “individuals to associate for the purpose of engaging in protected speech or religious activities.” Board of Directors of Rotary International v. Rotary Club, — U.S. -, 107 S.Ct. 1940, 1945 , 95 L.Ed.2d 474 (1987). Implicit in the right to engage in first amendment activities is the corresponding right to associate with others “in pursuit of a wide variety of political, social, economic, educational, religious, and cultural ends.” Roberts v. United States Jaycees, 468 U.S. 609, 622 , 104 S.Ct. 3244, 3252 , 82 L.Ed.2d 462 (1984). This court has said that social associations, to the extent that they are expressive, are not excluded from the safeguards of the first amendment. IDK, Inc. v. Clark County, 836 F.2d 1185 , 1194 (9th Cir.1988). Benigni claims that the City’s actions violated his right of association in both senses identified by the Supreme Court because the harassment interfered with his family relations and because it discouraged friends and patrons from frequenting the Silver Fox, thereby interfering with his social relations. Although the function of the Silver Fox is primarily commercial, Benigni does not thereby lose the protection of the first amendment, IDK, 836 F.2d at 1194, and we cannot say that there was clear error in submitting this theory to the jury.

(2) Fourth Amendment Claim

The court instructed the jury that there is a “constitutional right not to be subjected to unlawful search or seizure.” The court also read the text of Cal.Bus. & Prof. Code § 25755, which authorizes inspection of premises where alcoholic beverages are sold.

The evidence presented at trial indicates that police officers checked the Silver Fox as often as five or six times per evening, that officers went behind the bar, searched in drawers, shined flashlights in patrons’ faces, requested identification of persons obviously over 21, and walked through the bar with their hands on their guns. The verdict for the plaintiff reflects a determi nation that the bar checks in this ease were unreasonable because of the manner in which they were performed and their frequency. Clearly this theory of liability was correctly submitted to the jury, and there is evidence to support the verdict.

(3) Equal Protection Claim

An equal protection claim based on selective law enforcement activities is judged according to ordinary standards and the plaintiff must show both a discriminatory effect and a discriminatory motivation. Wayte v. United States, 470 U.S. 598, 608 , 105 S.Ct. 1524, 1531 , 84 L.Ed.2d 547 (1985). We disagree with the City that the equal protection issue should not have gone to the jury. The elements of an intentional discrimination claim are present in this case because the evidence was sufficient to show the discriminatory effect of greater law enforcement activity at the Silver Fox than at other bars, and the discriminatory intent of singling out Benigni based on his Italian ancestry. See Saint Francis College v. Al-Khazraji, — U.S. -, 107 S.Ct. 2022, 2027-28 , 95 L.Ed.2d 582 (1987) (targets of race discrimination for purposes of section 1981 include groups that today are considered merely different ethnic or national groups, such as Arabs, Jews, Germans and Italians).

(4) Due Process Claim

The due process clause protects a liberty or property interest in pursuing the “common occupations or professions of life.” Software v. Board of Bar Examiners, 353 U.S. 232, 238-39 , 77 S.Ct. 752, 755-56 , 1 L.Ed.2d 796 (1957); Chalmers v. City of Los Angeles, 762 F.2d 753, 757 (9th Cir.1985). On appeal the City argues that due process only applies when a plaintiff asserts infringement of a constitutional right or of a property right created by state law and that this case does not involve the sort of property right that, for example, a tenured teacher might enjoy. See, e.g., Board of Regents v. Roth, 408 U.S. 564 , 92 S.Ct. 2701 , 33 L.Ed.2d 548 (1972) (non-tenured teacher has no right to procedural due process). This argument misses the point that the constitutional right infringed in this case is the right to pursue an occupation. This claim was properly submitted to the jury.

The evidence before the jury was sufficient to support a conclusion that excessive and unreasonable police conduct was intentionally directed toward Benigni’s bar to force him out of business. The testimony reveals that bar checks occurred nightly, up to five or six times per night, that customers were frequently followed from the Silver Fox and sometimes arrested, that staff and customers frequently received parking tickets, that officers parked at the old train depot across the street, and that there were usually three or four officers there at all times in the evening, and that cars were often stopped in the vicinity of the Silver Fox for traffic violations that had occurred elsewhere.

Conclusion

Although the first amendment claim is weak, we choose to exercise our discretion to attribute the verdict to the other three legal theories. See Traver v. Meshriy, 627 F.2d 934, 938 (9th Cir.1980) (“the reviewing court has discretion to construe a general verdict as attributable to another theory if it was supported by substantial evidence and was submitted to the jury free from error”); accord McGrath v. Zenith Radio Corp., 651 F.2d 458, 464 (7th Cir.), cert. denied, 454 U.S. 835 , 102 S.Ct. 136 , 70 L.Ed.2d 114 (1981).

The general rule is that “a jury verdict will be upheld only if there is substantial evidence to support each and every theory of liability.” Syufy Enterprises v. American Multicinema, Inc., 793 F.2d 990, 1001 (9th Cir.1986), cert. denied, 479 U.S. 1031 , 107 S.Ct. 876 , 93 L.Ed.2d 830 (1987); Brocklesby v. United States, 767 F.2d 1288, 1294 (9th Cir.1985) (“the judgment must be reversed if any of the three theories is legally defective”), cert. denied, 474 U.S. 1101 , 106 S.Ct. 882 , 88 L.Ed.2d 918 (1986). These decisions rely on the Supreme Court’s view in Sunkist Growers, Inc. v. Winckler & Smith Citrus Products Co., 370 U.S. 19, 29-30 , 82 S.Ct. 1130, 1135-36 , 8 L.Ed.2d 305 (1962), that if one theory of liability is erroneous, it is unnecessary to explore the legality of other theo ries. However, this is a case that calls for the exercise of our discretion to uphold the jury’s verdict.

The Traver factors to be weighed in exercising discretion are:

627 F.2d at 938-39 .

This is not a case in which the jury was confused by the evidence. The facts developed at trial were the foundation for all claims and because we might say the facts more clearly support the legal claims of unreasonable search and seizure and violations of due process and equal protection, we cannot say that the jury was confused in its evaluation of the evidence or the claims. The defense of qualified immunity applied to all the claims, including the three upon which we think the verdict can most clearly be sustained. The evidence is sufficient to meet the deferential standard we must employ. Herrington, 834 F.2d at 1501. Finally, any disputed facts apply equally to all claims.

III. QUALIFIED IMMUNITY

This question is properly before the court because the individual defendants moved for a directed verdict on the basis of qualified immunity and subsequently offered it as a ground for judgment NOV. In reviewing jury instructions to which objections have been made, this court determines “whether, viewing the jury instructions as a whole, the trial judge gave adequate instructions on each element of the case to ensure that the jury fully understood the issues.” Los Angeles Memorial Coliseum Comm’n v. National Football League, 726 F.2d 1381 , 1398 (9th Cir.), cert. denied, 469 U.S. 990 , 105 S.Ct. 397 , 83 L.Ed.2d 331 (1984). The trial court has broad discretion in formulating instructions and will be reversed only upon a showing of an abuse of discretion. United States v. Wellington, 754 F.2d 1457, 1463 (9th Cir.), cert. denied, 474 U.S. 1032 , 106 S.Ct. 592 , 88 L.Ed.2d 573 (1985). A failure to submit a proper jury instruction is a question of law reviewable de novo, 999 v. C.I.T. Corp., 776 F.2d 866, 871 (9th Cir.1985), but an error in instructing the jury in a civil case does not require reversal if it is more probably than not harmless, Coursen v. A.H. Robbins Co., 764 F.2d 1329 , 1337 (9th Cir.1985).

Although the district court refused to grant a directed verdict or summary judgment for defendants Pease and Miller based on their claim of qualified immunity, it did instruct the jury on the defense as follows:

To explain the “relevant legal standard” the court then read the California statute authorizing inspections of bars. The City offered an instruction the court rejected, which stated:

The argument here centers on who has the burden of proof on the immunity defense. It is clear that qualified immunity is an affirmative defense, Harlow v. Fitzgerald, 457 U.S. 800, 815 , 102 S.Ct. 2727 , 73 L.Ed.2d 396 (1982), and we think it equally clear that the burden of proving the defense lies with the official asserting it, id. at 819 , 102 S.Ct. at 2738-39 (if the official pleading the defense can prove he did not know the relevant legal standard the defense should be sustained). We have expressly held that good faith is an affirmative defense that a police officer must prove. Heller v. Bushey, 759 F.2d 1371 , 1373-74 n. 1 (9th Cir.1985), vacated on other grounds, 475 U.S. 796 , 106 S.Ct. 1571 , 89 L.Ed.2d 806 (1986); Harris v. City of Roseburg, 664 F.2d 1121, 1129 (9th Cir.1981) (we recognize that good faith is an affirmative defense which must be proved by the officer).

A number of other circuits have reached the same conclusion, reading Harlow to say that because qualified immunity is an affirmative defense the burden of proving it lies with the defendant just as the burden of pleading the defense lies on the defendant, Gomez v. Toledo, 446 U.S. 635, 640 , 100 S.Ct. 1920, 1923-24 , 64 L.Ed.2d 572 (1980). See, e.g., Kompare v. Stein, 801 F.2d 883, 886 (7th Cir.1986); Tanner v. Hardy, 764 F.2d 1024, 1027 (4th Cir.1985); Arebaugh v. Dalton, 730 F.2d 970 (4th Cir.1984); Bauer v. Norris, 713 F.2d 408 , 411 n. 6 (8th Cir.1983); Alexander v. Alexander, 706 F.2d 751 (6th Cir.1983); but see, Zeigler v. Jackson, 716 F.2d 847 (11th Cir.1983) (per curiam) (once a defendant establishes his good faith, the burden shifts to the plaintiff to show lack of good faith); Saldana v. Garza, 684 F.2d 1159, 1163 (5th Cir.) (same), cert. denied, 460 U.S. 1012 , 103 S.Ct. 1253 , 75 L.Ed.2d 481 (1982).

We are unimpressed by the criticism of the burden of proof rule advanced in Payne v. Humboldt County, 655 F.Supp. 1341, 1343 (N.D.Cal.1987), and we reject the appellants’ suggestion that we should reconsider our prior decisions.

The defect in the district court’s instruction in this case is not the burden of proof but the failure to explain that what the defendants must prove is that their conduct was reasonable under the applicable standards even though it might have violated the plaintiff’s constitutional rights. Capoeman v. Reed, 754 F.2d 1512, 1513 (9th Cir.1985) (quoting Davis v. Scherer, 468 U.S. 183, 190 , 104 S.Ct. 3012, 3017 , 82 L.Ed.2d 139 (1984)). There is no prejudice from failure to give this instruction because the award of punitive damages against Pease and Miller indicates that the jury found their conduct to have been “in reckless or callous disregard of, or indifference to, the rights of the plaintiff,” and thus the jury would have found their conduct unreasonable under the applicable standards. The failure to give a proper instruction did not prejudice the defendants because the evidence would have supported a verdict for the plaintiff even with that instruction. See Kisor v. Johns-Manville Corp., 783 F.2d 1337, 1340 (9th Cir.1986) (the appellate court must consider “whether the instruction is misleading or states the law incorrectly to the prejudice of the objecting party”). Thus we conclude that any error in the qualified immunity instruction was harmless.

In considering the sufficiency of the evidence on this question, our standard of review is whether the jury verdict is supported by substantial evidence, that is, such relevant evidence as reasonable minds might accept as adequate to support a conclusion. Transgo, Inc. v. Ajac Transmission Parts Corp., 768 F.2d 1001, 1013-14 (9th Cir.1985), cert. denied, 474 U.S. 1059 , 106 S.Ct. 802 , 88 L.Ed.2d 778 (1986). The credibility of witnesses and the weight of the evidence are issues for the jury and are generally not subject to appellate review. Id. at 1024. A review of the record convinces us that there was sufficient evidence to support the jury’s rejection of the good faith defense.

IV. DAMAGES

This court does not disturb an award of damages on appeal unless it is clearly unsupported by the evidence or is “grossly excessive, monstrous, or shocking to the conscience.” Chalmers, 762 F.2d at 760 . We conclude that the evidence supports the award, and we do not find the award excessive.

V, ATTORNEY FEES

Attorney fees awards in a civil rights case under 42 U.S.C. § 1988 are reviewed for an abuse of discretion. Hensley v. Eckerhart, 461 U.S. 424, 437 , 103 S.Ct. 1933, 1941 , 76 L.Ed.2d 40 (1983); Hardin v. White Mountain Apache Tribe, 779 F.2d 476, 480 (9th Cir.1985).

The City argues that the court should not have awarded Benigni’s counsel $94,920 because the court did not do a sufficiently detailed analysis. The district court noted that Benigni’s attorney provided detailed documentation and that the time spent was reasonable. There was no abuse of discretion.

The City also argues that Jernigan should have received attorney fees because the jury did not find him liable for the violations of Benigni’s rights. The district court held that a defendant cannot obtain attorney fees unless the unsuccessful claim was frivolous, vexatious, or brought to harass or embarrass the defendant, Hensley, 461 U.S. at 429 n. 2 & 435 n. 10, 103 S.Ct. at 1937 n. 2 & 1940 n. 10, and that no such basis existed in this case. We agree. The City argues that Benigni “did not bother to present a case against defendant Jernigan” and thus he was named as a defendant for frivolous or vexatious reasons. This contention is without merit.

Benigni elicited testimony that Jernigan had been in the Silver Fox on eighteen occasions to conduct bar checks, that he stopped a number of motorists and pedestrians outside the restaurant, that he issued several citations to motorists driving in front of the restaurant, and that after a Silver Fox employee took a photograph of him inside the bar he vowed to the officer with him that he would get the employee. Although the jury did not find Jernigan liable for the violation of Benigni’s constitutional rights, it is clear that Benigni attempted to build a case against him. Jerni-gan is thus not entitled to fees under Hensley .

The judgment of the district court is AFFIRMED.

. The motion for directed verdict only asserted the qualified immunity of the individual appellants.
