The True Justice functioned as an Imperial detention vessel. Instead of conducting political prisoner trials on a planetary surface, where escape might be aided by the environment, these trials were conducted in the void of space.
In the year 18 BBY, the True Justice apprehended and detained Roan Lands along with Dona Telamark, intending to put them on trial. Nevertheless, Solace, Trever Flume, and Oryon successfully liberated them. They did this by disguising themselves as courtroom officials and demonstrating the innocence of the pair. Following this, they seized control of the ship's bridge and absconded with the vessel for their own purposes.
