Heading: The police officers unreasonably invaded the petitioner's privacy and violated his Fourth Amendment rights

Text: (7) Since we have concluded that the police officers did not comply with the requirements of section 844 and did not possess any excuse for failing to comply with that section, we must hold that an entry effected in violation of the provisions of section 844 or its companion section 1531 renders any subsequent search and seizure unreasonable within the meaning of the Fourth Amendment. ( Greven v. Superior Court, supra, 71 Cal.2d 287, 290; People v. Rosales, supra, 68 Cal.2d 299, 304-305.) As a consequence, an unexcused failure to fulfill the knock and notice requirements delineated by section 844 nullifies the subsequent search and requires exclusion of the evidence obtained. ( Mapp v. Ohio (1961) 367 U.S. 643, 655, 660 [6 L.Ed.2d 1081, 1089, 1093, 81 S.Ct. 1684, 84 A.L.R.2d 933]; People v. Benjamin, supra, 71 Cal.2d 296, 299; People v. Hamilton, supra, 71 Cal.2d 176, 178; People v. De Santiago, supra, 71 Cal.2d 18, 30; People v. Kanos, supra, 70 Cal.2d 381, 384.) Let a peremptory writ of mandate issue directing the respondent court to grant petitioner's motion to suppress the evidence obtained as a result of the search of petitioner's premises conducted on January 21, 1969.
