ECF 81. Before the Court are two motions to dismiss the Second Amended 17 Complaint (“SAC”) under Federal Rules of Civil Procedure 12(b)(6), the first brought by County, 18 and the second brought by City Defendants. ECF 84, 88. Plaintiff opposed to both motions. ECF 19 93. County and Morgan Hill Defendants filed replies. ECF 94, 95. The Court held a hearing on the 20 two motions to dismiss on April 17, 2025. ECF 98. 21 For the reasons stated below, the Court rules as follows: 1) GRANTS County’s motion to 22 dismiss WITHOUT LEAVE TO AMEND, and 2) GRANTS Morgan Hill Defendants’ motion to 23 dismiss WITHOUT LEAVE TO AMEND. 24 I. BACKGROUND 25 A. Factual Background 26 Plaintiff filed this action on February 9, 2024. ECF 1. The following facts are taken from 27 the SAC and are accepted as true for purposes of the motions to dismiss. 1 Plaintiff’s Arrest 2 On February 10, 2022, at about 8:14pm, Officers Martin, Donatoni, and Olson (collectively, 3 “MHPD Officers”) from the Morgan Hill Police Department (“MHPD”) arrived at Plaintiff’s house 4 in Morgan Hill to investigate a domestic violence allegation. SAC ¶¶ 22-23. The officers were 5 dispatched because Plaintiff’s wife, Wendy Mosgrove (“Ms. Mosgrove”) called 911 and alleged 6 that “[P]laintiff had pushed her into a bedroom closet and used his body physically to block her from 7 leaving the closet.” Id. Upon arrival, the Officers separated Plaintiff and Ms. Mosgrove. Id. ¶ 24. 8 Plaintiff walked outside with Officers Martin and Donatoni and Officer Olson walked inside the 9 residence and remained with Ms. Mosgrove. Id. While Plaintiff was detained outside his home, he 10 denied Ms. Mosgrove’s allegation that he physically or verbally abused Ms. Mosgrove, that he 11 blocked or impeded Ms. Mosgrove from exiting the closet, that he touched Ms. Mosgrove in a 12 harmful or offensive manner, and that he violated Ms. Mosgrove’s personal liberty. Id. ¶ 25. While 13 detained outside of his home, Plaintiff was informed by at least one officer that “whenever MHPD 14 officers are dispatched for a domestic violence incident, someone must be arrested without 15 exception.” Id. ¶ 26. 16 Eight minutes after the MHPD officers arrived at Plaintiff’s house, the MHPD Officers 17 decided to arrest Plaintiff. Id. ¶ 27. Plaintiff alleges that his arrest was without probable case. Id. 18 After Officer Martin initiated the arrest protocol, he spoke with Plaintiff’s son Maxwell William 19 Mosgrove (“Max”). Id. ¶ 28. Officer Martin told Max that “[it was] going to be an official arrest 20 and [Plaintiff was] going to have to see a judge because [it was] an allegation of domestic violence 21 and so because California is a mandatory arrest state he’s going to have to see a judge.” Id. Max 22 explained the dynamics of his parents’ relationship to Officer Martin and told Officer Martin that 23 he had never seen Plaintiff “get violent,” or “touch [] or hit [Ms. Mosgrove].” Id. ¶ 29. Officer 24 Martin told Plaintiff that “there were allegations made of domestic violence so in California as peace 25 officers we are mandated to take action.” Id. ¶ 31. Officer Martin also informed Plaintiff that he was 26 arrested for “domestic violence” based on his “marital status and [Ms. Mosgrove’s] allegation of 27 physical violence.” Id. ¶ 34. 1 domestic violence battery of spouse, and California Penal Code section 236, misdemeanor false 2 imprisonment. Id. ¶ 36. Plaintiff spent about five days in the Santa Clara County main jail. Id. ¶ 48. 3 Plaintiff was not charged for the alleged misdemeanors that led to his arrest. Id. 4 Defendants’ Unwritten Policy, Custom, or Practice 5 Plaintiff alleges that “[t]he County, and the City, including the MHPD, worked in concert 6 with one another to establish a longstanding, widespread, or well-settled custom or practice of 7 making unlawful arrests or seizures in all cases involving domestic violence allegations, regardless 8 of probable cause and without justification.” Id. ¶ 52. Plaintiff alleges that, in 1993, the County, the 9 Police Chiefs’ Association of Santa Clara County (“Association”) and the County of Santa Clara 10 Domestic Violence Council jointly developed the Domestic Violence Protocol for Law Enforcement 11 (“Domestic Violence Protocol”). Id. ¶ 53. Plaintiff alleges that, since 1993, the County, other County 12 department heads, the City, and other law enforcement agencies within Santa Clara County 13 “participate in meetings or otherwise jointly collaborate” to develop, review, and update the written 14 Domestic Violence Protocol.” Id. ¶ 55. Plaintiff alleges that, “as a result of those meetings or 15 otherwise joint collaboration, the County, the City, and/or other law enforcement agencies within 16 Santa Clara County, have [also] established a custom or practice of making arrests when responding 17 to domestic violence incidents regardless of probable cause or without justification.” Id. ¶ 55. 18 Plaintiff alleges that, through “joint collaboration,” the written Domestic Violence Protocol and the 19 unwritten custom or practice “is uniformly implemented throughout law enforcement agencies in 20 Santa Clara County.” Id. ¶ 57. Plaintiff does not allege that the written Domestic Violence Protocol 21 is unconstitutional. 22 In addition to Plaintiff’s arrest, Plaintiff identifies two separate domestic violence arrests 23 “within Santa Clara County.” Id. ¶ 62. First, on November 8, 2021, the Sunnyvale Police Department 24 arrested Neel Mehta (“Mr. Mehta”) pursuant to the City of Sunnyvale’s policy on domestic violence. 25 Id. ¶ 62(a). On February 3, 2024, the Santa Clara County Sheriff’s Office arrested Paul Davis (“Mr. 26 Davis”) in response to a call about domestic violence. Id. ¶ 62(b). Mr. Davis was not charged for 27 domestic violence. See id. Plaintiff alleges that these arrests were made without probable cause. Id. B. Procedural History 1 On April 25, Plaintiff filed the First Amended Complaint (“FAC”) against the City 2 Defendants, the County, the Association and District Attorney Jeffrey F. Rosen (“D.A. Rosen”). 3 ECF 31. On May 9, 2024, City Defendants answered the FAC. ECF 38. On May 28, 2024, the 4 County and D.A. Rosen moved to dismiss the FAC. ECF 41. On June 18, 2024, the Association 5 moved to dismiss the FAC. ECF 41, 49. On August 7, 2024, the Court granted the County’s and the 6 Association’s motions to dismiss with leave to amend and granted D.A. Rosen’s motion to dismiss 7 without leave to amend. See ECF 74. 8 On December 17, Plaintiff filed the SAC. ECF 81. In the SAC, Plaintiff dropped his claims 9 against the Association. See SAC. 10 II. LEGAL STANDARD 11 “A motion to dismiss under Federal Rule of Civil Procedure 12(b)(6) for failure to state a 12 claim upon which relief can be granted ‘tests the legal sufficiency of a claim.’” Conservation Force 13 v. Salazar, 646 F.3d 1240
