Alice tries to defend herself, but the judge and jury use Insane Troll Logic to convict her anyway.
Zig Zagged: There are fair judges, as there are corrupt ones.
Averted: Alex is a fair judge.
Enforced: The creator wanted to show just how much of a bastard a group was and decides to do it by having the hanging judge.
Lampshaded: "Hey, did you realize that the number of convictions has risen five-fold after Alex was appointed as a judge?" "Yeah, I wonder why..."
Invoked: Somebody wants Betty out of the way and uses a lot of money to get it made so.
Exploited: Betty, aware of impending verdict, decides to make a complete and total ass of herself during the trial, to the point that that the court is left with 2 options: Convict Betty and let her basically use this freedom to incriminate and insult everybody involved because she's already being punished, or let her go so she won't talk.
Defied: Betty exposes the judge before the trial so that a non-hanging judge could reside.
Deconstructed: After one too many false verdicts, someone informs the government about Alex, who is investigated for corruption. He is found guilty, and is stripped of his position.
Reconstructed: After a heavy checking, somebody noticed that the effect was actually positive to a point, and the government lets Alex keep going but assigns only very specific cases to him that would otherwise legally let a guilty party go.
