In a split vote, the Illinois Supreme Court upheld a Cook County judge's ruling that allows disgraced former Chicago police commander Jon Burge to keep receiving his pension.
In 2010, Burge was convicted of lying about police torture tactics that secured forced confessions from innocent men.
A city pension board said he is still entitled to his pension. Attorney general Lisa Madigan says he is not.
Burge, 66, is serving a 4½-year sentence in a federal prison for his 2010 conviction. He is scheduled to be released to a halfway house in the fall and to be freed on parole next February.
