The conviction of Tom Paris on the Banean homeworld for the murder of scientist Tolen Ren, punished by forcing him to relive the killing through the victim's eyes every fourteen hours.
In the Voyager episode Ex Post Facto, Paris and Harry Kim visit the Banean homeworld to work with the engineer Tolen Ren. Ren is stabbed to death, and Banean doctors extract his final memories, which appear to show Paris as the killer after a flirtation with Ren's wife Lidell.
The sentence is to have those memories implanted in Paris's brain so that he experiences the murder again and again. The implant reacts badly with human physiology and begins to damage him.
Tuvok investigates and mind-melds with Paris to examine the memory itself. He notices that the killer is the wrong height and knew Banean anatomy, and that the images carry hidden weapons data. The real culprits are Lidell and a Banean doctor spying for the Numiri, who meant to snatch Paris and the smuggled data.
