Ordered that the judgment is affirmed, without costs or disbursements.
In this proceeding the petitioner challenges the validity of the certificate of authorization permitting Rose Caracappa to be designated for nomination on the Republican Party line. The proceeding was properly dismissed since the petitioner failed to join as a necessary party the Executive Committee of the Suffolk County Republican Committee (see, CPLR 1001 [a]; Matter of Curcio v. Wolf, 133 A.D.2d 188).
In any event, were we to reach the substantive issue in this case, on this record, we would conclude that there is no merit to the appellant's contention. Mangano, J.P., Thompson, Brown and Weinstein, JJ., concur.
