In an abundance of caution, to the extent Federal Rule of Criminal Procedure 59, Federal Rule of Civil Procedure 72, and/or Local Civil Rule 72-2.1 are applicable in this case, Apple Inc. (“Apple”), by and through its counsel of record, hereby formally objects to the Court’s February 16, 2016 Order Compelling Apple Inc. to Assist Agents in Search (ED No. 15-451M, Dkt. 19) for the reasons set forth in Apple’s Motion to Vacate Order Compelling Apple Inc. to Assist Agents in Search, and Opposition to Government’s Motion to Compel Assistance (ED No. CM 16-10-SP, Dkt. 16).
