The Supreme Court quietly announced Monday that it would not review Bill Cosby's sexual assault case, leaving him a free man and ending a two-decade legal battle.

Cosby is now home following a decision out of Pennsylvania that found a secret promise to Cosby's lawyers made by the then-prosecutor - that he would never be charged for drugging and molesting Andrea Constand constituted an agreement.

Current prosecutors challenged that, maintaining it was not in writing.

The justices did not comment on why they would not review the case.

At least two other lawsuits remain pending against Cosby.
