1:00 PM PT -- Meek and his attorneys spoke outside the courthouse. Meek said he had low expectations going into the hearing, and Judge Brinkley didn't disappoint.

His attorney, Joe Tacopina was less subtle ... describing what went down in court as "an asylum."

12:40 PM PT -- The hearing is over, and Judge Brinkley did not make a ruling yet on Meek getting a new trial. Multiple reports describe the hearing as contentious.

Meek Mill marched into court Monday, ready to continue fighting for a new trial -- which could mean he goes free -- but that's IF his legal team can change Judge Genece Brinkley's mind.

Before he went into court for the hearing, Meek addressed a crowd of supporters rallying outside the Pennsylvania courthouse. The rapper thanked them for sticking with him, and allowing him to spend Father's Day with his son, and vowed to continue fighting for wrongly convicted inmates.

Of course, he's got his own battle to fight right now. Judge Brinkley's expected to hear evidence before deciding if Meek should get a new trial -- due to his arresting officer being at the center of a police corruption scandal.

Up to this point, she's dug in her heels and refused ... but we'll see if the state Supreme Court's decision to release Meek on bail affects her ruling this time around.
