NEW YORK (AP) — Michael Douglas has been watching from a New York courtroom audience as federal appeals judges consider the validity of his son’s nearly 10-year prison sentence for drug crimes.

A three-judge panel of the 2nd U.S. Circuit Court of Appeals listened to lawyers in Cameron Douglas’ case Wednesday. The judges didn’t immediately say whether they thought the sentence was legally justified.

Michael Douglas watched the proceedings and left the courthouse about an hour afterward. The Academy Award-winning actor said outside court there wasn’t much to say.

Cameron Douglas initially made a cooperation deal with the government and was sentenced to five years in prison for selling drugs. He was sentenced to another 4 1/2 years after he was caught using drugs in prison.
