Contractor Liable for Unauthorized Obstruction Injury

A contractor, hired for work on a building, failed to secure the necessary authorization from the property owner to store materials on the adjacent public sidewalk, resulting in damage to a pedestrian who tripped over the stored items. The court upheld the dismissal of the contractor's appeal, reasoning that the contractor, having caused the obstruction and injury on public property without proper authorization, was solely liable for the resulting damages, as the owner of the premises bore no responsibility for the contractor's unauthorized storage methods.
