2024The United States Supreme Court has long held that, under the Fourth Amendment, “the constitutional reasonableness of traffic stops” does not depend “on the actual motivations of the individual officers involved.” (Whren v. United States (1996) 517 U.S. 806, 813 (Whren).) This is because “[w]hether a Fourth Amendment violation has occurred ‘turns on an objective assessment of the officer’s actions in light of the facts and circumstances confronting [him or her] at the time,’ [citation], and not on the officer’s actual state of mind at the time the challenged action was taken.” (Maryland v.

2022An interaction between a police officer and citizen changes from a consensual encounter to a detention, and “a person has been ‘seized’ within the meaning of the Fourth Amendment only if, in view of all of the circumstances surrounding the incident, a reasonable person would have believed that he was not free to leave.” (United States v. Mendenhall (1980) 446 U.S. 544, 554 ; see also Wilson v. Superior Court (1983) 34 Cal.3d 777, 790 ; People v. Rivera (2007) 41 Cal.4th 304, 309 [“There is no Fourth Amendment violation as long as circumstances are such that a reasonable person would feel free

2013There is no Fourth Amendment violation as long as circumstances are such that a reasonable person would feel free to leave or end the encounter. [Citations.]” (People v. Rivera (2007) 41 Cal.4th 304, 309 .) “„[I]n order to determine whether a particular encounter constitutes a seizure, a court must consider all the circumstances surrounding the encounter to determine whether the police conduct would have communicated to a reasonable person that the person was not free to decline the officers‟ requests or otherwise terminate the encounter.‟ [Citation.] This test assesses the coercive effect of

2021(See People v. Woods (1999) 21 Cal.4th 668, 673 .) We review independently whether the search or seizure was legal under the Fourth Amendment requirement of reasonableness.

2018Thus, we must ‘view the facts upon which the suppression motions were submitted in the light most favorable to the People, drawing therefrom all reasonable inferences in support of the trial court’s order denying 5 the motions.’ [Citation.]” (People v. Dominguez (1988) 201 Cal.App.3d 345, 353 ; see also People v. Woods (1999) 21 Cal.4th 668, 673 .)

2025When, as here, a defendant is lawfully arrested based on probable cause, “a search incident to the arrest requires no additional justification.” (People v. Macabeo (2016) 1 Cal.5th 1206, 1213 .) Further, a search incident to arrest extends to items on the defendant’s person and in his or her 8 possession. “ ‘It is settled Fourth Amendment doctrine that a police officer may, incident to a lawful arrest, conduct a contemporaneous warrantless search of the arrestee’s person and of the area into which the arrestee might reach to retrieve a weapon or destroy evidence.’ [Citation.] Such searches may

2024(Id. at pp. 995–996.) The court held that “the search warrants were written with sufficient particularity because the items listed on the warrants were qualified by phrases that emphasized that the items sought were those related to child pornography,” and thus, “[p]olice officers executing the warrants were not unguided and free to rummage through Hall’s property.” (Id. at pp. 996–997, fn. omitted.) 33 “Exclusion of evidence due to a Fourth Amendment violation is not automatic.” (People v. Macabeo (2016) 1 Cal.5th 1206, 1219 (Macabeo).) “The exclusionary rule applies only ‘where its deterrenc

2021“The touchstone of Fourth Amendment analysis is whether a person has a ‘constitutionally protected reasonable expectation of privacy.’ ” (California v. Ciraolo (1986) 476 U.S. 207, 211 ; Robey v. Superior Court (2013) 56 Cal.4th 1218, 1224 .) “ ‘ “An illegal search or seizure violates the federal constitutional rights only of those who have a legitimate expectation of privacy in the invaded [space] or the seized thing. [Citation.] The legitimate expectation of privacy must exist in the particular area searched or thing seized in order to bring a Fourth Amendment challenge.” ’ ” (People v. Cart

2021Defendant relies on Robey v. Superior Court (2013) 56 Cal.4th 1218, 1242 , for the position that we should not consider Fourth Amendment exception theories that were not the basis of the trial court’s determination.

( Id . at pp. 770-771, 86 S.Ct. 1826 .) But the court noted that its "judgment that there had been no Fourth Amendment violation was strictly based 'on the facts of the present record.'
