Meek Mill is back in court trying to get his conviction overturned from over a decade ago -- and he might have a shot based on who's on the bench ... a whole new set of judges.

The Philly-bred rapper is appearing Tuesday in Pennsylvania Superior Court, asking for his 2008 conviction on gun and drug charges to be tossed out based on shoddy evidence that was initially used by a cop who has since been revealed to be crooked.

Not only that, but even state prosecutors have recommended he get a new trial ... and did NOT oppose his release on bail after he got thrown back in prison for a few months in late 2017.

You'll recall ... Genece Brinkley, the judge who initially sent Meek to prison all those years ago, sent him back to the slammer in November 2017 after she found he'd violated his probation -- sentencing him to 2-4 years behind bars ... an incredibly harsh punishment.

Meek's legal team believes this stemmed from a long-standing vendetta the judge has against the rapper ... partly because he laughed at her prior suggestion of him doing a remake of Boyz II Men's "On Bended Knee" and giving her a shout-out.

After a lot of public outcry and petitioning by movers and shakers in and around the city ... Meek was finally released, much to the chagrin of Judge Brinkley.

Luckily for him, she isn't hearing his request this time around -- Meek is coming face-to-face with a panel of judges, who will decide whether the OG case from 2008 was legit or not.

Stay tuned ...
