The Supreme Court is weighing whether an anti-racketeering agency at the East Coast’s busiest port has outlived its purpose. Justices on March 1 heard arguments on whether New Jersey can unilaterally withdraw from a bi-state compact with New York that established the Waterfront Commission of New York Harbor.

The Wall Street Journal reports that the case will determine the future of crime-fighting and labor regulations on the docks. New Jersey and shipping industry groups say the agency imposes needless costs and red tape that impairs business at the port. New York counters that the commission is as relevant as ever. 

The commission has helped bring down dozens of members of organized crime as well as union officials in the International Longshoremen’s Association. Federal law enforcement officials say the commission continues to be helpful in policing organized crime on the docks. A decision is expected before July.
