The decision adopts a broader, functional interpretation of the “interstate commerce” exemption, focusing on the worker’s role in the interstate flow of goods rather than whether the worker personally crosses state lines or interacts with interstate transportation. As a result, more workers—including “last-mile” drivers—may fall outside the FAA and avoid mandatory arbitration.
The Court declined to adopt a bright-line rule, leaving room for continued litigation over the exemption’s boundaries. Future disputes will likely focus on whether a worker’s duties are sufficiently connected to the interstate transportation process.
