A dispute is shaping up about whether Philadelphia defense attorney A. Charles Peruto Jr.’s lawsuit against Roc Nation and Amazon over a leaked audio recording should be heard in state or federal court.

Peruto sued the two national companies, as well as IPC Television and Sixx Degrees Media, in September, claiming that the defendants leaked audio of him allegedly bashing one of his clients—Philadelphia Court of Common Pleas Judge Genece Brinkley, who is presiding over the controversial case involving embattled hip-hop star Meek Mill. The lawsuit seeks control of the audio, which was allegedly recorded as part of a documentary series that was being filmed.
