Best practice

Use "case closed" to signal a definitive end to a discussion, investigation, or argument. Ensure the context clearly indicates that the matter is fully resolved and not open for further debate.

Common error

Don't use "case closed" if there's still room for discussion or if new evidence could potentially surface. Prematurely declaring "case closed" can undermine credibility if the situation isn't truly resolved.
