In a pair of decisions last week involving Pennsylvania’s Motor Vehicle Financial Responsibility Law, the state Supreme Court resolved questions about the law’s provisions for stacking uninsured/underinsured motorist coverage.

In a rare opinion modifying the court’s earlier decision in Sackett v. Nationwide Mutual Insurance Co., the state Supreme Court has ruled that the addition of a new car to an existing insurance policy does not require the insurer to obtain a new waiver for stacked UM/UIM coverage. Justice Thomas Saylor wrote the majority opinion.
