Mr. Belding and Screech are promoting the "Rainy Day Indoor Sports Festival," with the winning team getting a trip to Catalina Island. Eric is plagued by a tough guy, Bull Grabowski. Maria likes Scott Miller, but he already has a girlfriend, Natalie. Screech gives citations to Eric, Maria and Ryan for minor offenses and makes them appear before the Student Court. When the kids protest their sentences, Screech cancels the punishment but makes them into the new judges for the Court. The kids all abuse their positions on the court to help them win the Festival competition: Eric gives Bull a stiff sentence for chewing gum, Maria manipulates a breakup between Scott and Natalie so she can be Scott's partner, and Ryan "sentences" Nicky and Katie to detention in the gym so they can practice pool. Katie's a great pool player and Ryan makes a bet with some other guys in a game with her. When Belding catches them, he sends them to Ryan for punishment, and he makes it clear he expects Ryan to do the right thing. When the case comes up, Maria and Eric are ready to let Nicky and Katie off with a slap on the wrist, but Ryan, the chief judge, overrules them and gives them the prescribed punishment of no extracurricular activities for a month, which means they will miss the Festival and Ryan will most likely miss out on a weekend in Catalina with Rachel. Maria and Eric agree, and they undo the unfair sentences they gave to their competitors. Guest starring: Caroline Keenan as Natalie
