A hearing held on Deep Space 9 in 2372 to decide whether Worf should be handed to the Klingon Empire for destroying a civilian transport during a battle, which proved to be a staged deception.
Worf's extradition hearing is the subject of the Deep Space Nine episode Rules of Engagement. While the Defiant is escorting a relief convoy and fighting off Klingon warships, a vessel decloaks in front of it and Worf orders it destroyed. The Klingons say it was a transport carrying 441 civilians and demand that he be given up for trial.
A Vulcan admiral, T'Lara, hears the case. The Klingon advocate Ch'Pok argues that Worf acted as a warrior hungry for battle and not as a Starfleet officer, and he provokes Worf into striking him in the courtroom. Benjamin Sisko conducts the defence.
Odo discovers that every name on the passenger list belongs to someone who died in an earlier crash. The transport was empty, and the affair was arranged to discredit the Federation and stop its convoys. Worf is cleared, though Sisko tells him he should not have fired.
