California Legal Brief

The Rule of Microsoft Corporation v. Superior Court of Los Angeles County is that a trial court may issue a nondisclosure order prohibiting an electronic service provider from notifying its enterprise customer of a search warrant's existence, under circumstances where the court has reviewed a sealed affidavit and found that disclosure could cause adverse results enumerated in CalECPA, even when the provider proposes to notify only a "trusted contact" at the customer organization who is not the target of the investigation.
