ARMANDO DIAZ, Case No. 1:23-cv-00065 JLT EGC

Plaintiff, ORDER DENYING MOTION FOR SUMMARY JUDGMENT v. (Doc. 44) CITY OF MERCED, et al., Defendants. Armando Diaz alleges police officers wrongfully detained and arrested him in violation of his rights under the Fourth Amendment. The defendants seek summary judgment of that claim. (Doc. 44.) The motion is DENIED in light of genuine disputes of material fact that remain to be resolved at trial. The Court must assume at this stage that a factfinder would resolve disputes about the relevant evidence in Diaz’s favor, as well as draw justifiable inferences in his favor. See Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 255 (1986). The following summary takes the evidence from that point of view. On a January evening several years ago, Diaz had arranged to pick up his daughter from his former partner, Rivas, at a house on a cul-de-sac in Merced, California. (Doc. 46-3 at 1.) She was not outside when he arrived, so he waited in his car on the street. (Id. at 2.) After several minutes, Rivas came outside and told him that their daughter did not want to leave. (Id.) They spoke briefly, standing several feet apart. (Id.) Diaz eventually decided to go. (Id.) He went back to his car. (Id.) As he did, he noticed a police car was parked at the corner, a few houses away. (Id.) When he drove past it, the officer inside shone a light into his car and signaled for him to pull over. (Id.) He did. (Id.) The officer’s name was McComb. (Doc. 44-4 at 2) McComb had received a call for service about a “domestic violence incident” at a house at the end of the cul-de-sac. (Id.) He does not explain what evidence he had, if any, that might have suggested to him that Diaz had done anything wrong, let alone that Diaz had committed a domestic violence offense, but he stopped Diaz and asked what he was doing. (Id.) Diaz explained that he had come to pick up his daughter, as he and Rivas had planned, but that Rivas had not wanted to let her go with him, and Diaz said that he had decided to leave. (Id.) McComb told Diaz to wait, and he stayed with Diaz by his car while another officer (de Jong) went to speak with Rivas. (See Doc. 46-3 at 2.) After a few minutes, McComb told Diaz to get out of the car, said he was under arrest, and put him in handcuffs in the back of a patrol car. (Id.; see also Doc. 44-4 Ex. 1 (body camera video).) De Jong had told McComb that there was probable cause to arrest Diaz for domestic violence. (Doc. 44-4 at 2.) McComb does not say what else de Jong told him, if anything, or why de Jong thought there was probable cause to suspect that Diaz had committed a domestic violence offense. (See id.) De Jong has not filed a declaration to explain what he heard or saw, either. The only person to explain is a third officer, Saelee, who arrived after Diaz was arrested. (See Docs. 44-5 at 2; 46-3 at 2.) Saelee claims he spoke to Rivas again, and he claims that Rivas told him that Diaz had shouted at her and had grasped her arm, leaving a bruise. (Doc. 44-5 at 2–3.) Saelee took a picture of her arm. It shows a few small red marks and, possibly, a faint bruise. (Doc. 445- at 5–8.) Diaz was eventually charged with a violation of California Penal Code 273.5(a), a misdemeanor. (Doc. 46-4 at 16–18.) Before trial, he moved to suppress some of the evidence against him under Penal Code 1538.5, arguing the officers stopped and arrest him in violation of the Fourth Amendment to the U.S. Constitution. (See Docs. 46-1 at 12, 36–; 44-3 at 15–21.) The court granted his motion in part based on its conclusion that McComb was wrong to stop and detain him; the court denied the motion in part because the officers had probable cause to suspect domestic violence based on Rivas’s allegations and the possible bruising on her arm. (See Docs. 44-3 at 20; 46-4 at 36–128.) The Court suppressed Diaz’s statements to McComb but not Rivas’s statements to de Jong and Saelee. (See Doc. 46-4 at 119–24.) The case went to trial, and the jury reached a verdict of not guilty, both of the charge under section 273.5 of the state Penal Code and of a lesser included charge, under section 243. (Docs. 46-4 at 20–21.) Diaz then filed a motion under Penal Code 851.8. (See Doc. 46-4 at 4–12.) The state supreme court has said that section 851.8 was created “for the benefit of those defendants who have not committed a crime.” People v. Adair, 29 Cal. 4th 895, 905 (2003) (quoting People v. Scott M., 167 Cal. App. 3d 688, 699 (1985)). It permits them to “show that the state should never have subjected them to the compulsion of the criminal law—because no objective factors justified official action.” Id. (quoting Scott M., 167 Cal. App. 3d at 700). If they can meet that standard, they can “purge the official records of any reference to such action.” Id. (quoting Scott M., 167 Cal. App. 3d at 700). The court granted Diaz’s motion. (Doc. 46-4 at 266–67.) It ordered the state and the police department to seal and eventually to destroy the records of his arrest. (See id.) Diaz then filed a federal civil rights lawsuit against the City of Merced and the three officers (McComb, DeJong and Saelee) in this Court. (Doc. 1) He asserts claims under 42 U.S.C. § 1983 for unreasonable seizure and excessive force in violation of the Fourth Amendment, and he asserts claims under state law for battery, negligence, intentional infliction of emotional distress, and violations of the Tom Bane Civil Rights Act. (Id.) The defendants move for partial summary judgment of the first claim only. (Doc. 44.) The motion is fully briefed, and the court determined that oral arguments were not necessary. (See Docs. 44-1, 46–48.) Under the well-known provisions of Federal Rule of Civil Procedure 56(a), the question is whether there is any “genuine dispute as to any material fact” and if not, whether the defendants are “entitled to judgment as a matter of law.” /// The defendants first argue that the state court’s pretrial decision is the decisive and final word on whether the officers had probable cause, even in this follow-on federal case. (Docs. 44-1 at 6–7; 48 at 5.) To be clear, the defendants limit this argument to probable cause and the arrest; they set Diaz’s initial detention to the side. (See Doc. 44-1 at 1, 5–7.) This limitation creates an awkward juxtaposition. On the one hand, the defendants argue that the state court’s decision is the last word when it comes to probable cause, but then, on the other hand, they ask this Court to decide that McComb had reasonable suspicion to stop and detain Diaz, contrary to the state court’s pretrial ruling at the same hearing. (See id. at 5.) In any event, it is Diaz’s position that none of state court’s pretrial decisions is decisive or controlling on any relevant issue. (See Doc. 46 at 11–12.) The legal terminology for these types of disagreements is notoriously obtuse. (It’s “collateral estoppel” or “issue preclusion” in this instance.) The basic idea is simple enough: • An issue in a case is identical to an issue that was already litigated in the past. • That issue was actually resolved in the previous case, and necessarily so. • The decision in the previous case was also final, and it was on the merits of that issue itself. • The person who lost in the first case is the same person who is trying to relitigate the issue in the second case. In this situation, the person who lost in the first case cannot try again in the second case. The issue is “precluded.” See Mills v. City of Covina, 921 F.3d 1161, 1170 (9th Cir. 2019) (citing Gikas v. Zolin, 6 Cal. 4th 841, 849 (1993)). It’s not hard to see why
