Can an interest rate be 'unconscionably' high? The California Supreme Court will decide

One of the named plaintiffs, Eduardo De La Torre of Redwood City, was a student at UC Davis when he borrowed $2,600 from CashCall at an interest rate of 98%, according to the lawsuit. He would have had to pay back more than $9,000, a sum CashCall should have known De La Torre could not afford, according to the suit.
