County Republican committees and dozens of party members, including sitting lawmakers, filed court papers this week challenging bylaws adopted by the Montana Republican Party at its June convention, arguing the new rules give party leadership unchecked authority to remove elected precinct representatives and party members from office.
The filing, submitted as an amicus brief in support of an ongoing lawsuit, represents an unusually public split within the state GOP. The group backing the challenge includes 67 Republicans, three county central committees, 11 sitting state representatives, 6 state senators, and 12 Republican nominees for the legislature, spanning 13 Montana counties.
The Disputed Rules
The contested bylaws, approved by 97 percent of delegates at the party’s June convention, give state GOP leaders the ability to remove members at will and define Republican membership characteristics. They also establish term limits for precinct officers and central committee officers, and create new suspension and removal procedures for party members.
State GOP Chairman Art Wittich has defended the changes, stating that “there is a difference between self-identifying as a Republican and voluntarily participating as a full member of our party, a political association with its own rules, responsibilities and authority.”, as first reported by the Daily Montanan
The grassroots group challenging the bylaws argues they blur the line between party discipline and control over voter-elected offices. In their brief, members contend that “the Montana Republican Party transforms private membership discipline into a power over positions and nominations created and filled through Montana’s election laws.”
Court Action So Far
A lawsuit challenging the bylaws was filed in early July in Lewis and Clark District Court. Judge Michael McMahon initially issued a temporary restraining order blocking enforcement of the bylaws, but later narrowed it to apply only to certain disputed sections.
The state GOP has argued that the overwhelming delegate support for the bylaws demonstrates they are not a “power grab by a few” and that plaintiffs have not shown they have suffered direct harm. Party officials also assert a First Amendment right to determine whom the organization can associate with and what standards members must meet.
McMahon has not signaled when he will issue a ruling on whether to grant an injunction that would block the bylaws from taking effect while the lawsuit proceeds.
Broader Party Divisions
The challenge reflects ongoing friction within Montana’s Republican establishment. The opposition spans significant party infrastructure: it includes representatives from Glacier, Pondera, and Teton County Republican Central Committees, with more than 20 signatories from Ravalli County alone. The group also encompasses precinct committee representatives, party activists, and candidates running for legislative seats in the 2026 election.
The dispute centers on whether the party can use its bylaws to remove duly-elected Republican nominees or precinct representatives who were chosen by voters in their districts. The grassroots group’s brief specifically objects to any mechanism that would allow the state party to “terminate party membership or participation” of precinct representatives or candidates selected through Montana’s election process.
The court’s eventual ruling could reshape how the Montana Republican Party operates, determining whether bylaw amendments can override voter-chosen party officers or whether such changes must respect the electoral choices made in individual precincts and counties across the state.
