Tech-giant Apple filed a formal objection late Tuesday in the case involving an FBI request to unlock an iPhone used by one of the San Bernardino shooters, NBC News reported.
The document filed in U.S. District Court made good on Apple's promise to fight a judge's Feb 16. order compelling it to assist investigators. Apple "formally objects" to the order out of an "abundance of caution," the filing says.
The phone in question is the iPhone 5C used by San Bernardino shooter Syed Rizwan Farook. It's owned by his employer.
The U.S. District Court for the Central District of California will hear from both parties in the Apple vs. FBI case at a hearing on March 22.
