Parsley V. Superior Court Of Riverside County

Defendants, charged with violation of three sections of the Health and Safety Code, moved unsuccessfully to set aside the information pursuant to Penal Code section 995,*fn1 and failed to obtain a writ of prohibition in the Court of Appeal. We granted defendants' petition for hearing in order to decide whether a magistrate who issues a search warrant may relieve police officers of the statutory duty to give notice of their authority and purpose before entering a house to serve a warrant.
