The United States Supreme Court has refused to hear an appeal from former R&B singer R. Kelly over his 2022 convictions on charges for alleged child pornography, leaving him with no further direct appeals from a verdict that sentenced him to 20 years in prison.

Kelly’s attorneys had compelled the high court to take the case, which a federal jury in Chicago convicted him in September 2022, by arguing that the case should have been barred by the statute of limitations.

Billboard reports that in an order on Monday, October 7, the justices declined to tackle the case. The court did not explain its decision to reject Kelly’s case along with dozens of others. The Supreme Court receives thousands of petitions per year and only decides to hear a small percentage of them.

The October 7 order dealt with only one of Kelly’s two separate sex abuse allegations. The other – a September 2021 guilty verdict on alleged racketeering charges brought by prosecutors in New York that resulted in a 30-year prison sentence – is still pending on appeal before a lower appellate court.

In the current case, a separate team of federal prosecutors from Chicago accused Kelly of allegedly violating child pornography laws, allegedly enticing minors for sex and allegedly obstructing justice by upending a 2008 criminal trial.

Though he was acquitted on certain counts, Kelly was convicted in September 2022 and subsequently sentenced to 20 years in prison; the vast majority of that sentence will be served simultaneously with the New York sentence. The conviction was affirmed by a lower appeals court earlier this year.

Kelly’s attorney Jennifer Bonjean cited the statute of limitations when asking the justices to consider overturning the ruling. She said that an updated federal law extending the time limit, passed in 2003, could not be applied retroactively to Kelly’s alleged crimes, which occurred in the late 1990s and early 2000s.

“Retroactive application of the 2003 amendment not only fly in the face of congressional intent,” Bonjean wrote. “It violates notions of fundamental fairness.”

Excluding an unusual result in the future, the decision on October 7 effectively finalized Kelly’s convictions and sentencing in the Chicago case. However, the separate convictions in the New York case could still be overturned, either by the lower appeals court or by the Supreme Court.

Kelly’s attorney did not immediately respond to a request for comments.
