On stardate 46910.1, the Klaestrons attempted to extradite Jadzia for the murder of Klaestron military leader Ardelon Tandro, a murder which was attributed to Curzon, as they believed that joined Trills were answerable to another host's crimes. When a hearing was later held on Deep Space 9, Sisko represented her, although it was the appearance of Enina Tandro, Tandro's widow, that revealed the truth and exonerated Jadzia and Curzon. (DS9 episode: "Dax")
