closes the book on

Ends the matter

To close the book on something is to bring it to a definitive end, treating it as finished and no longer open for discussion or revision.

The image is of shutting a volume that won't be reopened: The verdict closes the book on a decade-long investigation.

Often implies finality after prolonged uncertainty or dispute.
