Does a police officer's failure to comply with Welfare and Institutions Code sections 626 and 627 render a confession inadmissible?

We reject defendant's suggestion that the officers' failure to comply with Welfare and Institutions Code sections 626 and 627 rendered his confession inadmissible. There is no exclusionary rule relating to a violation of these provisions. (People v. Lessie, supra, 47 Cal.4th at p. 1170.)⁴ Moreover, we have determined that the confession was voluntary, and the failure to comply with the requirements of the statute does not invalidate a voluntary confession. (See id. at pp. 1169-1170.)
