In a proceeding pursuant to Election Law § 16-102, inter alia, to invalidate petitions designating Joseph J. Fonseca, Joseph A.
Ordered that the final order is affirmed, without costs or disbursements.
In seeking to invalidate designating petitions based on the alleged failure of the Executive Committee of the State Committee of the Working Families Party (hereinafter the Executive Committee) to comply with Election Law § 6-108, the petitioners challenge the actions and authority of the Executive Committee. Accordingly, the Executive Committee is a necessary party to the proceeding, and the petitioners’ failure to join it was jurisdictionally fatal (see CPLR 1001 [a]; Matter of Flores v Kapsis, 10 AD3d 432, 433 [2004]; Matter of Barbuto v Sarcone, 275 AD2d 424, 425 [2000]; Matter of Jenkins v Board of Elections of City of N.Y., 270 AD2d 436, 437 [2000]; Matter of Regan v New York State Bd. of Elections, 207 AD2d 647 [1994]; Matter of Oberle v Caracappa, 133 AD2d 241 [1987]; Matter of Curdo v Wolf, 133 AD2d 188, 189 [1987]). Therefore, the Supreme Court properly granted the motion to dismiss the proceeding.
In light of our determination, we need not address the parties’ remaining contentions. Schmidt, J.R, Rivera, Santucci, Fisher and Covello, JJ., concur.
