Romulus and Remus
Case File: Remus vs. Romulus
Case Description: Complainant (Remus) accuses Defendant (Romulus) of murder. The brothers decided to found a city of their own, but couldn't agree which hill to build it on. When Remus mocked his brother by jumping over a wall that he was building, Romulus skewered his twin with a sword.
Case Status: Case dismissed. Romulus was king after this, so he kind of pardoned himself. Heck, he even honored himself by naming the city Rome.
