Jared "Coop" Cooper (Jacob Kraemer): Coop, 15, is a cool, fun, articulate charmer who never thought he'd voluntarily participate in any extracurricular activities that didn't involve his favourite pursuits: playing drums, sports and girls. But during his first week of tenth grade, Coop takes on one of the recently vacated lawyer positions in Banting High's teen court, and discovers his charm and confidence make him a natural for legal work. Through the series it is noticed Coop has a crush on Kaleigh, but he decides not tell her his true feelings when she rejects Ronald and swears off boys.
Kaleigh Stewart (Sally Taylor-Isherwood): In the courtroom, Kaleigh, 15, is super-efficient and super-serious. Outside the courtroom, she likes to think she loosens up, but Coop would argue the contrary. Of course, when it comes to Kaleigh, Coop always argues the contrary. Kaleigh loves her job as a lawyer because it's the one place she feels totally in control. She knows exactly what to do, what to say and how to act. Outside the courtroom she's just as confused about the rules of being a teenager as anyone. Through the series it is noticed Kaleigh has a crush on Coop.
Russell "Rusty" Dougal (Nick Spencer): Being the court clerk is serious business for Rusty, 15, who confidently bumbles his way through every court procedure. It's Rusty's job to make sure things run smoothly in the courtroom and, to everyone's surprise, he often succeeds. Rusty takes great pride in his court but once court is out of session he's just another awkward teenager in the hall. He is also known to be loyal, a popular quality for Scottish people.
Tara Bohun (Jasmine Richards): Tara, 15, is Banting High's teen court happy-go-lucky judge. Though she may seem illogical and scatterbrained, her roundabout way of looking at things always leads to verdicts that are spot on. Speaking with Tara, you'd never know that her convoluted and bizarre logic would translate into courtroom decisions that actually show great insight and clarity, or that underneath her trendy clothes lurks a razor-sharp legal mind who calls things like she sees them.
Linda Cooper (Tammy Isbell): Coop's mother who is just as normal as any mom. She and Gil, her husband, always want what's best for their kids.
Gil Cooper (Tom Barnett): Coop's father who is a normal dad
Jordana 'Jordy' Cooper (Sara Waisglass): Jordy, Coop's little sister, likes to pick on her brother just like any sister. She is known to be really bright for her age but also has a good friendship with her peers. She is gifted. In one episode, Jordy was interested in a boy, but it is not known if she is really interested in other boys.
