A hearing held on Deep Space 9 to decide whether Jadzia Dax could be extradited to Klaestron IV for treason and murder allegedly committed thirty years earlier by her previous host, Curzon.
In the Deep Space Nine episode Dax, Ilon Tandro of Klaestron IV attempts to abduct Jadzia Dax from the station, then presses a formal extradition request. He accuses Curzon Dax of betraying his father, General Ardelon Tandro, to rebels during his world's civil war, leading to the general's death.
Because the station is Bajoran, a Bajoran arbiter, Els Renora, hears the case. Sisko argues that Jadzia is a new person who cannot answer for Curzon, while Tandro insists that the symbiont carries the guilt. Jadzia herself refuses to offer any defence.
Odo's enquiries on Klaestron IV resolve the matter. The general's widow, Enina Tandro, comes forward to say that Curzon was with her when the fatal message was sent, and hints that her husband was himself the traitor. The request is dropped.
