   MEMORANDUM

The Estate of Joshua Levy and David Breidenbach (collectively, plaintiffs) appeal the district court’s order granting summary judgment on behalf of the City of Spokane, the County of Spokane, and certain individual law enforcement defendants. Plaintiffs allege that the defendants used constitutionally excessive force against Levy — an individual known to have serious mental health problems — resulting in Levy’s fatal jump from a bridge. Because the parties are familiar with the factual and procedural history of this case, we repeat only those facts necessary to resolve the issues raised on appeal. We affirm.

To overcome a qualified immunity defense, a plaintiff must establish both: (1) that the defendants violated a statutory or constitutional right; and (2) that the right was “clearly established” at the time of the challenged conduct. Pearson v. Callahan, 555 U.S. 223, 232, 129 S.Ct. 808, 172 L.Ed.2d 565 (2009). In analyzing this issue, we may address either prong first. See id. at 236, 129 S.Ct. 808. If analysis of one prong proves dispositive, we need not analyze the other. See id. at 236, 241-43, 129 S.Ct. 808.

“A Government official’s conduct violates clearly established law when, at the time of the challenged conduct, ‘[t]he contours of [a] right [are] sufficiently clear’ that every ‘reasonable official would have understood that what he is doing violates that right.’ ” Ashcroft v. al-Kidd, — U.S. -, 131 S.Ct. 2074, 2083, 179 L.Ed.2d 1149 (2011) (quoting Anderson v. Creighton, 483 U.S. 635, 640, 107 S.Ct. 3034, 97 L.Ed.2d 523 (1987)). Plaintiffs cite Deorle v. Rutherford, 272 F.3d 1272 (9th Cir.2001), for the proposition that the defendants were on notice that it was unlawful to attempt to use a Taser to temporarily incapacitate a fatigued and unresponsive mentally-ill individual who was contemplating suicide, and to further “rush” that individual in order to detain him and bring him to safety. See al-Kidd, 131 S.Ct. at 2084 (holding that courts must not “define clearly established law at a high level of generality”). Plaintiffs contend the defendants’ actions were particularly unreasonable because Levy was not inside the bridge portico at the time the defendants acted. Deorle, however, is inapposite, and plaintiffs cite no other case, let alone a “robust consensus of cases of persuasive authority,” id. at 2084 (citation omitted), that clearly establishes the illegality of the defendants’ conduct here. Because the defendants could have reasonably believed that their conduct under these circumstances was lawful, they are entitled to qualified immunity.

Plaintiffs' Monell claims also fail, because plaintiffs cannot show that any municipal defendant ratified the individual defendants' actions. See City of St. Louis Praprotnik, 485 U.S. 112, 127, 108 S.Ct. 915, 99 L.Ed.2d 107 (1988) (holding that a municipality can be held liable for an isolated constitutional violation if a final policymaker ratified a subordinate's actions). Here, plaintiffs point to no evidence to support their ratification theory. For instance, plaintiffs never identity the relevant "authorized policyrnakers" for any defendant. See id. Nor do plaintiffs present evidence that demonstrates that any authorized policymaker approved of the individual defendants' actions.

Finally, Breidenbach’s emotional distress claim fails because it is derivative of plaintiffs’ rejected constitutional claims.

AFFIRMED. 
      
       This disposition is not appropriate for publication and is not precedent except as provided by 9th Cir. R. 36-3.
     
      
      . The claims raised in defendants' cross-appeal are denied as moot.
