From the first season of Justice League:
A galactic tribunal convenes to place Green Lantern John Stewart (Phil LaMarr, MadTV) on trial for the destruction of a neighboring planet. Despite his teammates' willingness to defend him, Stewart convinces himself he's guilty. Uh-oh.......
At the heart of the problem is a classic JLA foe, Kanjar Ro (Rene Alberjonis, ex-Star Trek: Deep Space Nine, Benson), who is a witness for the prosecution, but that ain't all. Flash (Michael Rosenbaum, Smallville) decides to be GL's defense attorney, but he comes off more as comedy relief, as his stall tactics epically fail.
Luckily, the truth comes out at the end.....!
