Two weeks after a district court judge heard arguments on whether the Montana Republican Party's newly adopted bylaws are unconstitutional, a broad coalition of rank-and-file Republicans filed a brief siding with the plaintiffs — a move that underscores how deeply the fight over party governance has split Montana's GOP.
The brief was filed by 67 individual Republicans along with representatives from three county central committees, adding significant weight to a lawsuit that state party chairman Art Wittich has framed as a fringe challenge to legitimate party reorganization. Wittich was elected chairman at the party's June 2026 convention in Missoula, where the contested bylaws were also adopted. The fact that sitting county committee members — the grassroots infrastructure of the party — are now formally aligned against those bylaws signals the dispute runs deeper than a personality conflict at the top.
The lawsuit argues the new bylaws are unconstitutional, though the specific legal grounds were the subject of the district court hearing held roughly two weeks before the brief was filed. Courts examining internal party rules typically weigh questions of free association, state election law, and whether party structures improperly limit participation by registered members or duly elected delegates.
Helena-area Republicans will feel the reverberations of this fight regardless of how it resolves. Lewis and Clark County sends delegates to state party functions, and the outcome of the lawsuit could determine which faction controls the machinery that shapes candidate endorsements, platform language, and party resources heading into the next election cycle. No ruling has been issued yet; the district court took the matter under advisement following the hearing.
