A historic nonprofit in South Florida is facing off against the city of Delray Beach in a contractual dispute that has ignited local pushback and could have implications in the tens of millions of dollars.

Marko Cerenko, a shareholder at Kluger Kaplan in Miami, is representing the Old School Square Center for the Arts Inc. in a lawsuit against Delray Beach and several additional parties in Palm Beach Circuit Court. He said the dispute between the parties escalated on Aug. 10, when the city terminated Old School Square's lease, allegedly without cause.
