The Southeastern Pennsylvania Transportation Authority filed a federal lawsuit Thursday alleging its commercial landlord lied about and failed to fix dangerous building conditions, forcing significant disruption in the transit authority’s operations.

Lead attorney for the plaintiff, Michael A. Iannucci of Blank Rome, filed the nine-count complaint, Southeastern Pennsylvania Transportation Authority v. Drummond Decatur and State Properties LLC, in the U.S. District Court for the Eastern District of Pennsylvania.
