AUGUSTA — The Maine Legislature will hold a special session on Sept. 27 to consider a congressional reapportionment plan, Gov. Paul LePage announced today.

Congressional redistricting is required to be updated every 10 years to reflect population shifts measured by the U.S. Census. A federal judge has ordered the Legislature to complete its work redrawing the line between Maine’s 1st and 2nd Districts by Sept. 30. The new districts will be in effect by the 2012 election.

A bipartisan commission of seven Republicans, seven Democrats and one independent moderator has already begun the process of redistricting. Commission member Rep. Kenneth Fredette, R-Newport, in a statement said the commission is working to create a plan that can win overwhelming legislative support.
