Is the insurance company within its rights to deny any

Question

1. Amir Labib gets a reduced rate from his auto insurance company because he represents in his application that he commutes less than ten miles a day to work. Three years later, he and his wife buy a new residence, farther away from work, and he begins a fifteen-mile-a-day commute. The rate would be raised if he were to mention this to his insurance company. The insurance company sees that he has a different address, because they are mailing invoices to his new home. But the rate remains the same. Amir has a serious accident on a vacation to Yellowstone National Park, and his automobile is totaled. His insurance policy is a no-fault policy as it relates to coverage for vehicle damage. Is the insurance company within its rights to deny any payment on his claim? How so, or why not?
2. In 2009, Peter Calhoun gets a life insurance policy from Northwest Mutual Life Insurance Company, and the death benefit is listed as $250,000. The premiums are paid up when he dies in 2011 after a getaway car being chased by the police slams into his car at fifty miles per hour on a street in suburban Chicago. The life insurance company gets information that he smoked two packs of cigarettes a day, whereas in his application in 2009, he said he smoked only one pack a day. In fact, he had smoked about a pack and a half every day since 1992. Is the insurance company within its rights to deny any payment on his claim? How so, or why not?
