Good Faith Exception to the Exclusionary Rule Does Not Apply Where the Search Warrant is 84 Days Old - Penal Code Section 1538.5
A recent California Court of Appeals decision in People v. Hirata held that a search warrant is invalid after the passing of a substantial period of time. In this case, the period of time was 84 days.
The defendant (Hirata) was charged with possessing drugs and being part of a drug conspiracy ring. Investigators had built substantial evidence against Hirata and a number of other co-conspirators. Armed with this information, the authorities put together an affidavit and were able to secure a search warrant for a number of the residences believed to be a part of the conspiracy. The search warrant was signed and put into effect on June 14; however, it was not executed (when the search actually took place) until September 4.
