The U.S. Census Bureau releases census data on April 25, 2021; New York State loses one congressional seat due to loss of population.

During the 2021 New York State Legislative session, the Democrat-controlled state Senate and Assembly pass legislation that gives control of the redistricting process to themselves, the partisan Legislature, if the Independent Redistricting Commission (IRC) reaches an impasse. The IRC holds numerous public hearings throughout the state over the remainder of 2021.

New Yorkers reject, via statewide popular vote, a constitutional amendment proposed by the Democrat-controlled state Legislature that would repeal portions of the state constitutional amendment adopted by voters in 2014 that created the independent redistricting commission (IRC).

The Independent Redistricting Commission (IRC) cannot reach a consensus on new maps, so it presents two different plans to the Legislature; one by Democratic members of the IRC and the other by Republican members. At that point, the IRC abandoned its constitutional duty by refusing to meet and the Legislature rejected both sets of maps.

A group of concerned New York voters file a lawsuit with the New York Supreme Court against New York’s Governor, Lt. Governor, legislative leaders, State Board of Elections, and the Legislative Task Force on Demographic Research and Reapportionment, challenging both the state’s previous and enacted congressional redistricting plans as violating the New York Constitution.

A New York Supreme Court Justice issues his decision striking down the state’s congressional, state Senate, and state Assembly plans as unconstitutional.

The New York Supreme Court’s Appellate Division issues an order temporarily staying the Supreme Court’s decision until April 7 pending the parties; arguments take place as to why a complete stay should or should not be issued while the case proceeds through the appellate process.

Oral arguments are held before the Court of Appeals. The Court of Appeals holds that both the congressional and state senate redistricting plans were enacted in violation of the state’s constitutional redistricting process and the congressional plan was drawn with unconstitutional partisan intent. Both maps are declared void. The Court affirms the lower courts' finding of unconstitutional partisan intent underlying the congressional plans creation as sufficiently supported by the facts and evidence in the record, specifically noting the finding that it was drawn to discourage competition.

The court-approved non-partisan special master submits his final report and congressional and state Senate redistricting plans to the court, and the court issues an order adopting them as final the same day.

The court issues an order adopting minor revisions to the senate and congressional plans based on recommendations from the State Legislative Task Force on Demographic Research and Reapportionment.

Elections are held to elect 26 U.S. Representatives from New York State using the court-drawn map. New Yorkers vote to elect 15 Democrats and 11 Republicans, creating a balance of representation which is proportional to the total popular vote in these elections (56% D to 44% R).

Out of state law firms, paid by the Democratic Congressional Campaign Committee (DCCC), argue before appellate judges in Albany in favor of tossing out the court-drawn districts and returning the mapmaking powers to New York’s Independent Redistricting Commission, and ultimately, the State Legislature that gerrymandered the lines in the first place.

The Appellate Division of the State Supreme Court in Albany rules that the competitive, court-drawn districts put in place for the 2022 midterms had only been a temporary fix. The court orders the IRC to promptly restart a process that would effectively give the Democrat-controlled State Legislature final say over the contours of New York’s 26 House seats through the 2030 elections.
