According to the attorneys who filed the lawsuit over the deadly 2017 fire in London’s Grenfell Tower, the case, which involves more than 200 named plaintiffs, is one of the largest products liability lawsuits in Pennsylvania history. But whether the case remains in the Keystone State may depend on several issues currently working their way through the Pennsylvania appellate courts.

The massive lawsuit stems from the June 2017 fire that engulfed a 24-story building in the North Kensington section of West London. The fire, allegedly ignited by a defective refrigerator and exacerbated by faulty cladding and insulation, burned for several hours and eventually left 72 dead and dozens more injured.
