The judge in the 'Rust' case has refused to let the prosecutor retry Alec Baldwin for involuntary manslaughter.
The prosecutor wanted to reopen the case because they thought the judge made a mistake when dismissing it earlier.
However, the judge said the prosecutor's request was too long and didn't follow the court's rules about how long legal documents can be.
The prosecutor might try to appeal the judge's decision, meaning the case could go to a higher court.
