The Utah omnibus election law bill, SB 13, moves the petition deadline for a new party from February 15 to November 15 of the year before the election. Here is a copy of the bill. See section 7. The sponsor is Senator Margaret Dayton, but it appears the bill is really sponsored by the state elections office.

Petition deadlines for new parties in the odd years before election years have never been upheld. Utah is in the Tenth Circuit and there are no Tenth Circuit precedents on petition deadlines for newly-qualifying parties, except that in 1988 the Oklahoma May 31 deadline was upheld. New Mexico is in the Tenth Circuit and in 2012 a U.S. District Court struck down the April petition deadline for new parties.

In 2000 the U.S. State Department charged that Azerbaijan was violating human rights standards because it was considering moving the deadline for a new party to be organized to six months before the election.
