jective reasonableness” standard applicable in a suppression hearing under United States v. Leon, 468 U.S. 897, 104 S.Ct. 3405, 82 L.Ed.2d 677 (1984) also defines the qualified immunity available in a § 1983 damages action. Briggs, 106 S.Ct. at 1098. The Court expressly rejected the view that a police officer’s reliance on a warrant is per se objectively reasonable merely because a judicial officer has found probable cause exists. Id. The question for the district court to decide on remand is “whether a reasonably well-trained officer in [appellee's] position would have known that his affidavit failed to establish probable cause and that he should not have applied for the warrant.” Id.
The appellees argue that this court should not apply the Briggs standard retroactively because under Harlow v. Fitzgerald, 457 U.S. 800, 818, 102 S.Ct. 2727, 2738, 73 L.Ed.2d 396 (1982) a government official can be liable only for violation of “clearly established statutory or constitutional rights.” This argument is misplaced. Neither the case at bar nor Briggs involves a substantive constitutional right whose newly emerging status raises the question of when officials may properly be charged with knowledge of its existence. See, e.g., Mitchell v. Forsyth, 472 U.S. 511, 105 S.Ct. 2806, 86 L.Ed.2d 411 (1985) (warrantless wiretaps not clearly unconstitutional until after United States v. United States District Court, 407 U.S. 297, 92 S.Ct. 2125, 32 L.Ed.2d 752 (1972)); Capoeman v. Reed, 754 F.2d 1512 (9th Cir.1985) (cutting inmate’s hair violated first amendment rights, but applicable standard unresolved at time of incident); Ward v. San Diego County, 791 F.2d 1329 (9th Cir.1986) (policy of strip searches of minor offense arrestees, if unreasonable, gives rise to § 1983 liability under legal standards obtaining in May 1981).
This case and Briggs involve the fundamental, and long-established, rights protected by the fourth amendment. Briggs, 106 S.Ct. at 1098, addressed an allegedly unconstitutional arrest and the instant case implicates the fourth amendment’s core “right of a man to retreat into his own home and there be free from unreasonable governmental intrusion.” Silverman v. United States, 365 U.S. 505, 511, 81 S.Ct. 679, 683, 5 L.Ed.2d 734 (1961). See also United States v. United States District Court, 407 U.S. at 313, 92 S.Ct. at 2134 (“[P]hysical entry of the home is the chief evil against which the wording of the Fourth Amendment is directed.”).
Briggs in no way alters the substantive law governing searches, it merely establishes that the qualified immunity from damage suits is no broader than the good faith exception to the exclusionary rule. The search at issue here took place in May of 1984, some two months before the Supreme Court first created a good faith exception to the exclusionary rule in Leon, 468 U.S. 897, 104 S.Ct. 3405, 82 L.Ed.2d 677 (1984), and thus the involved officers had no reason to imagine that an allegedly unconstitutional search would lead to anything but suppression of any evidence obtained and/or to personal liability for any damages sustained.
Liability for Wrongful Execution of the Warrant
The district court dismissed this claim holding that the manner, place, and justification of the search were reasonable, that the defendants had no reasonable grounds to believe the warrant did not authorize the search they conducted, and that mistaken execution of a warrant on the wrong property does not rise to the level of a constitutional violation. In this regard, since the federal agents were not present at the time of the search, dismissal of the claim as to the Government was proper.
We have already indicated Briggs, 106 S.Ct. at 1098 holds that the officers’ reliance on the warrant is not per se reasonable merely because a magistrate found probable cause. Even should the district court conclude upon remand that the reliance was reasonable, the question remains whether the complaint states a claim for damages under § 1983 for an unreasonable execution of the warrant. Officers’ conduct in executing a search warrant is
