US Magistrate Judge Paul Grewal has invited to plaintiffs to file for sanctions in their ongoing lawsuit against Apple over location tracking, Bloomberg reports. The company was recently chastized for not showing compliance with a November order to turn over demanded documents in the case. Grewal has called Apple's behavior "unacceptable conduct," and notes that after he began overseeing the case earlier this month, Apple has "more than doubled" the amount of documents produced.
