Introduction

On October 6, 2025, the United States Supreme Court denied certiorari in Syngenta Crop, LLC v. Nemeth, passing on an opportunity to clarify its prior decision in Mallory v. Norfolk Southern and address whether Pennsylvania’s “consent to jurisdiction” statute violates the dormant Commerce Clause. The result: for now, out-of-state corporations registered to do business in Pennsylvania remain subject to general personal jurisdiction in the Commonwealth, regardless of the extent of their in-state operations.

As the demand for clean energy and transportation grows, so does the need for rechargeable batteries. Lithium-ion batteries are widely used, from small toys to electric cars to large energy storage systems. While some lithium-ion batteries are already subject to regulations, rechargeable batteries used in “micro-mobility devices” such as electric bikes and scooters are currently not subject to any federal safety standards. Some advocates contend that a lack of regulation has led to an increase in fires caused by poor quality, defective batteries. According to a report by CBS News New York, defective lithium-ion batteries have allegedly resulted in 400 fires, 300 injuries, and 12 deaths between 2019 and 2023 in New York City alone.
