Case closed
Meaning
This phrase signifies that an investigation, discussion, or matter is definitively concluded, with no further questions or actions required.
Origin
The phrase "case closed" vividly conjures the dramatic scene of a hardboiled detective, a victorious grin spreading across his face as he slams a file shut, the mystery finally unraveled. While its origins are deeply rooted in the formal language of legal and investigative proceedings, where a "case" refers to a matter under inquiry, its definitive punch and widespread popularity surged in 20th-century American pulp fiction, radio dramas, and later, film noirs and television shows. Detectives, often world-weary and cynical, would utter this line, bringing a satisfying, final resolution to their labyrinthine tales. It became more than just a legal term; it transformed into a powerful declaration of absolute finality, a mic drop moment signaling that all questions had been answered and all debates concluded.
Examples
- After the forensic report confirmed the suspect's alibi, the detective confidently declared, case closed.
- You've presented a very compelling argument, so as far as I'm concerned, case closed on where we're having dinner.
