R. Kelly is appealing his federal sex crimes convictions to the U.S. Supreme Court, arguing that the charges related to his conduct from the 1990s exceed the statute of limitations. His legal team contends that the 2003 PROTECT Act, which removed the statute of limitations for child sex crimes, should not be applied retroactively. Previously, a federal appeals court upheld his convictions, ruling that the statute of limitations could be extended if the defendant was prosecutable when the law was amended. Kelly's appeal is pending, and the Supreme Court will decide whether to hear the case after the Justice Department submits its response. If the appeal is not granted, Kelly remains scheduled for release in 2045.
