R 4551.New York voting and elections database.
Article 45. Evidence · Last amended 2026 · Last verified July 21, 2026
Full Text of CPLR 4551
Plain-English Summary
Election-related litigation often turns on voter rolls, registration figures, and similar records the state board of elections maintains in its voting and elections database. CPLR 4551 gives that data a procedural head start in court: any data, information, or estimates maintained in the database, or copies of them provided to the attorney general as required by the election law, receive a rebuttable presumption of validity whenever a claim in a court proceeding puts them at issue.
A rebuttable presumption does not mean the data is beyond challenge. It means the party relying on the database does not have to independently prove the numbers are accurate before a court will accept them; the burden instead falls on the party disputing the data to come forward with evidence showing it is not valid.
The rule reflects a broader effort to give courts a reliable evidentiary shortcut for election data in litigation over voting rights, redistricting, or election administration, without requiring the state board of elections to authenticate its own records in every case that touches them.
