Ali is a forty-year-old man. He was insured under a health insurance policy since March 2023. Last month he was urgently operated on unsuccessfully. Upon further investigations, the insurance company discovered that Saad had been skydiving for five years. Ali did not tell his insurance agent about practicing this sport when he applied for the policy. The insurance company decided not to pay the medical costs of the surgery, so he decided to file a lawsuit against the insurance company to claim the company's costs.
