What does rome has spoken the case is closed mean?

The phrase "Rome has spoken, the case is closed" refers to a definitive decision made by a higher authority, particularly in matters of doctrine or ecclesiastical law within the Catholic Church. It suggests that once the Vatican or the Pope has made a ruling, there is no further discussion or appeal on the matter. This expression emphasizes the finality and authority of such decisions, akin to the phrase "the verdict is in."
