As previously reported, the Maine Republican Party has filed a federal lawsuit, alleging that the First Amendment’s Freedom of Association clause permits the party to decide for itself whether it wants to use ranked choice voting in its primaries. The Maine Republican Party also argues that the supporters of ranked choice voting should not be allowed to intervene in the lawsuit.

Here is the 8-page brief of the Committee for Ranked Choice Voting, defending its right to intervene in the case. The judge will decide in a few days whether to approve intervention. Thanks to Tony Roza for this news.
