Since being sent to prison for a technical probation violation in November, rapper Meek Mill’s case has come before the Pennsylvania Supreme Court twice. It helped bring to light a list of police officers with questionable credibility, and spurred hundreds of new appeals. It led one court employee to be fired, raised an ethical cloud over the judge who ordered that prison sentence, and, in the process, fueled a national conversation about the fairness of the criminal justice system in Philadelphia and beyond.

The case has seen a staggering number of twists and turns over the past seven months, but Mill and his legal team are coming to a critical point in the hip-hop star’s fight to have that prison sentence overturned.
