Meek Mill Wants Judge Off His Case as Fans and Celebrities Sign Petition for His Release (Details, pics)

Meek Mill is going after the judge as he believes he locked him up because of a personal vendetta... TMZ says.

Meek's attorney, Joe Tacopina, reveals that he's filing a motion for the judge to remove herself from his case, and will also be filing an official complaint with the judicial conduct board.  As we reported, the judge allegedly has it out for Meek because he wouldn't do a Boyz II Men song with a shout out to her in the middle.

Tacopina feels the judge's bad blood with Meek Mill led to the stiff sentence of 2 to 4 years for the multiple probation violation.

Tacopina says Meek will also be applying to Pennsylvania's Board of Pardons ... but it was reported that there is more of a Hail Mary because it's normally a 3-year process at least.

There's a petition circulating, calling for the BOP and Philadelphia Governor, Tom Wolfto have Meek's "unjust prison sentence remedied" -- which is now 300,000 strong -- it probably won't help much. A spokesperson for Wolf says his hands are tied by state law.
