In an early test of the U.S. Supreme Court’s recent ruling on public-sector union dues, New Jersey faces a challenge to a state statute limiting when government employees can leave their labor union.

Three building inspectors for the township of Lakewood filed a lawsuit in federal court on Oct. 3 that seeks to overturn state-imposed restrictions on their ability to resign from their union and to stop paying dues. They claim the Supreme Court’s June 27 ruling in  Janus v. AFSCME Council 31 is contradicted by a New Jersey law adopted May 18, the Workplace Democracy Enhancement Act. That act says union members may resign from the bargaining unit only during the 10-day period after the anniversary date of their employment.
