State Assembly and Senate leaders proposed new legislative districts, but critics called the maps gerrymandered to protect incumbents and unfair to minority groups. The proposal, by a legislative task force, would increase the size of the Senate to 63 members, from 62; the Democratic minority in the Senate has disputed the legality of that move. Legislative leaders on Sunday proposed revisions to the Senate and Assembly maps, but critics have derided the maps as still being tailored to incumbents. Shortly before midnight on Monday, Judge Mann filed her final proposal for Congressional districts for a panel of federal judges to consider. The proposal reflected only minor changes from her draft map. On Tuesday, Gov. Andrew M. Cuomo, who had promised to veto any maps drawn by the Legislature, defended his efforts to strike a deal with legislative leaders over Senate and Assembly redistricting. Under a compromise plan being discussed, Mr. Cuomo would allow lawmakers to draw their own districts in return for the promise of an amendment to the State Constitution that would modify the redistricting process after the 2020 census, as well as a law that would back up that amendment. A senior administration official said that the revised Senate and Assembly maps released on Sunday were acceptable to the governor, and that he would sign them as long as lawmakers passed the backup statute he is seeking. In a radio interview on Tuesday, Mr. Cuomo said, "I would like to reform this once and for all, so that no other governor goes through this." The federal judicial panel will now consider Judge Mann's proposal for new Congressional districts. The judges have asked for objections to the plan to be filed by noon on Wednesday, and have scheduled a public hearing for Thursday at the federal courthouse in Brooklyn. The judicial panel wants to put a Congressional map in place by Tuesday, when the petitioning period for prospective House candidates is scheduled to start. The panel has also asked legislative leaders to submit an update on their progress drawing new Senate and Assembly districts to the court by Thursday.
