R. Kelly is asking the U.S. Supreme Court to throw away his various child sex convictions, TMZ reported on Tuesday (July 30).

The R&B singer’s lawyer, Jennifer Bonjean, argued that the PROTECT Act’s 2003 launch date means that her client’s actions in the previous decade shouldn’t fall under his misconduct that happened decades ago. The PROTECT Act took away statutes of limitations for abduction and abuse cases that involved children when the president at the time, George W. Bush, signed it into law in April of that year. Bonjean said statutes of limitations should still apply.

According to the outlet, the high court will decide in the next few months whether to hear R. Kelly’s appeal. 

The “Step in the Name of Love” hitmaker is currently serving a 20-year sentence for producing child pornography and inducing minors to engage in sexual activities. These offenses are dated from 1991 to 2018 and has been the subject of a long-term investigation by the Chicago Sun-Times since August 2000.
