A more thorough explanation:

eat inde sine die

When a defendant is acquitted or a prisoner is released, the term "eat inde sine die" is used to indicate that the matter is dismissed without any further legal action.

• After the jury found him not guilty, the judge declared "eat inde sine die" and the defendant was free to go.
• The prisoner had served his sentence and was released from jail with the words "eat inde sine die" from the judge.

These examples show how "eat inde sine die" is used to indicate the end of a legal matter without any further action needed.
