MEMORANDUM

Eugene Darrell Rutledge, a California state prisoner, appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging that defendants violated his Fourth Amendment rights when they detained him for a six-day period as a robbery suspect before they obtained a judicial determination of probable cause as to the state robbery charges. We have jurisdiction under 28 U.S.C. § 1291 . We review de novo. Morrison v. Hall, 261 F.3d 896, 900 (9th Cir.2001). We affirm.

The district court properly granted summary judgment because the undisputed evidence shows that there was a valid federal warrant establishing probable cause for Rutledge’s arrest and detention. See United States v. Bueno-Vargas, 383 F.3d 1104, 1107 (9th Cir.2004) (“When an arrest has been made subject to a warrant, a judicial determination of probable cause has already been made as a prerequisite to obtaining the arrest warrant.”); see also John v. City of El Monte, 515 F.3d 936, 940 (9th Cir.2008) (“Probable cause is an objective standard and the officer’s subjective intention in exercising his discretion to arrest is immaterial in judging whether his actions were reasonable for Fourth Amendment purposes.”); Kanekoa v. City and County of Honolulu, 879 F.2d 607, 612 (9th Cir.1989) (“The fourth amendment does not prohibit the police from investigating a suspect while the suspect is legally detained.”).

The district court did not abuse its discretion in granting defendants’ motion for enlargement of time to file a dispositive motion because defendants promptly submitted the motion after learning of their oversight. See Preminger v. Peake, 552 F.3d 757 , 769 n. 11 (9th Cir.2008) (setting forth the standard of review of a district court’s decision concerning its management of litigation); see also United States v. W.R. Grace, 526 F.3d 499, 509 (9th Cir.2008) (en banc) (noting that “[district courts have inherent power to control their dockets” and that “judges exercise substantial discretion over what happens inside the courtroom” (citations and internal quotation marks omitted)).

The district court did not abuse its discretion in declining to enter default against defendants “[g]iven the lack of merit in appellant’s substantive claims.” Aldabe v. Aldabe, 616 F.2d 1089, 1092-93 (9th Cir.1980) (per curiam).

Rutledge’s remaining contentions are unpersuasive.

Rutledge’s “Motion to Consolidate Filing and Docketing Fees” is denied.

AFFIRMED.
