Michigan voters cut CMS Energy off from the officials deciding its $443 million rate case
Proposal 2 passed with 82% on November 3 and CMS Energy sued two days later. From about December 3 the utility cannot fund the Michigan politicians and regulators who rule on its $443 million rate case, a 1-gigawatt data center and a $27 billion buildout.

Eight in ten voters said yes; the utilities went to court in two days
Michigan passed Proposal 2 on November 3, 2026, with 3,549,433 yes votes against 805,411, about 82% 1. Section 30a, the provision it added, bars electric and gas utilities, their executives, their family members and their affiliates from contributing to state candidates, party committees and members of the Michigan Public Service Commission, the appointed board that rules on utility rates, while unions and advocacy groups keep that right 2.
A tenfold fine, no cure, and a federal suit in two days
A violation carries a fine of up to 10 times the contribution, with no safe harbour and no cure by returning the money 2. On November 5 CMS Energy−2.12% — CMS Energy, down 2.12 percent today, Consumers Energy, DTE Energy+0.16% — DTE Energy, up 0.16 percent today and its subsidiaries, two political action committees and two individuals sued in federal court in Grand Rapids to block it 2. One plaintiff is DTE's treasurer; the other is his mother, covered solely because the law reaches executives' immediate family 2.
The other side is ready. Samuel Bagenstos, the University of Michigan law professor defending the measure, says it was drafted with existing court decisions in mind; campaign manager Maura Cowley called the suit no surprise 3.
The decisions that matter next all sit inside the ban's blast radius
Consumers Energy wants $443 million of added electric revenue at a 10.25% return on equity; commission staff back $265 million at 9.85%, and the year's approved gas order landed at $139 million, about 60% of that ask 4. Meanwhile an up-to-1-gigawatt data center Consumers agreed to serve, reported as Microsoft−0.86% — Microsoft, down 0.86 percent today, still works through zoning in multiple locations, outside the 745 MW of new contracts signed and 450 MW already energized 567. Chief executive Garrick Rochow blames campaign "spin" for the opposition 5.

That is the machine at stake: a 10.5% rate-base growth target, a $27 billion buildout through 2040, 2026 adjusted EPS guidance of $3.83 to $3.90, and a negative Moody's−2.02% — Moody's, down 2.02 percent today outlook on the utility 4. Third-quarter GAAP earnings fell to $0.39 a share from $0.92 7. Investors marked CMS down 2.12% on Friday 8.

The pen now belongs to a judge
Certification lands November 23 and Section 30a takes effect around December 3 2. The Mackinac Center's parallel suit attacks the disclosure rules reaching journalists and nonprofits 9. Watch one thing: whether a federal judge freezes the ban before December 3, because that single order decides whether CMS argues its $443 million case funded or muzzled 9.
