In 1966, the Senate was expanded from 21 to 40 members and the General Assembly from 60 to 80. Following a United States Supreme Court decision in 1964 and a New Jersey Supreme Court decision in 1972, the state's legislative districts were reapportioned into the current arrangement. Two more modern developments have also helped shape the Legislature: the increase in importance of legislative committees and the development of longer tenures for the legislative leadership.
