In New York before the recent amendment, both congressional and state legislative district boundaries were drawn by the state legislature, which could be vetoed by the governor. A six-member advisory commission assisted in the process. The commission recommended congressional and state legislative redistricting plans to the legislature, which could adopt, modify or ignore the commission’s. proposals.
The members of the commission were appointed by the majority leader of the New York State Senate, the majority leader of the New York State Assembly, the minority leader of the New York State Senate, and the minority leader of the New York State Assembly.
In 37 states, legislatures are primarily responsible for the drawing of congressional district lines. Seven states use backup commissions and other procedures in case the state legislatures are unable to decide on redistricting.
Independent commissions draw the lines for both state legislative and congressional districts in six states: Alaska, Arizona, California, Idaho, Montana and Washington. These commissions do not include legislators or other elected officials.
