Polly sold Jason a used car for 1,000. Their contract provided that the engine in the car was in good shape, a true statement as far as Polly knew. The day after Jason purchased the car, it broke down and was discovered to have significant engine problems. Jason told Polly that he wanted a refund. Polly told Jason the he was not entitled to a refund because she did not lie and as far as she knew, there was nothing wrong with the car. Is jason entitled to a refund?
Would this fall under Mistake of Judgement or Mistake of Fact?
