The U.S. Court of Appeals for the Seventh Circuit has affirmed a district court’s finding that an insurance company had no duty to defend or indemnify a fireworks distributor for the injuries sustained to two volunteers at a July 4 fireworks display.

The volunteers, Timothy Olson and Todd Zdroik, helped with the displays in separate towns in 2018. Olson opened and closed a bin from which other volunteers retrieved fireworks during show in Rib Lake, Wisconsin. Zdroik worked as a “shooter” by manually lighting fuses on the mortar shells at the Land O’Lakes, Wisconsin, firework display, according to the circuit court’s opinion filed Monday.
