Within weeks of the initiative’s passage, two Maine-based Super PACs and a Republican political operative sued to block the new law’s implementation, arguing that limits on contributions to Super PACs represent an unconstitutional infringement on free speech. In July 2025, a federal district court judge ruled in their favor, preventing Maine from enforcing the contribution limits. The district court ruling relies on
SpeechNow v. FEC, a 2010
D.C. Circuit Court ruling that declared limits on Super PAC contributions to be unconstitutional. Immediately after the ruling, Maine Attorney General
Aaron Frey and the advocacy organization
Equal Citizens appealed the case to the
First Circuit Court of Appeals, arguing that
SpeechNow was wrongly decided. As of January, 2026, the appeal is ongoing. If successful, it could overturn the precedent set by
SpeechNow, allowing Maine’s contribution limits to take effect and reviving existing limits on super PAC donations, including at the federal level. == References ==
