A new law in New Jersey barring “gender identity or expression” discrimination, in effect as of June 17, is already stirring debate among New Jersey employment lawyers, who say its provisions are so broad that they will require fine tuning by the courts.

The statute, which amends the Law Against Discrimination, N.J.S.A. 10:5-1 et seq., shields transsexuals and other individuals never before protected as a class. New Jersey is the sixth state to do so, after California, Illinois, Minnesota, New Mexico and Rhode Island.
