Return to legislature.mi.gov for House and Senate session calendars — track any supplemental appropriations bills that ride emergency-management headlines after EO 2026-10.
Sunday, May 10, 2026 — Runoff week on the Lower Peninsula, voltage in Lansing and Grand Rapids
This edition tracks power in two registers: who moves electrons and acres under Public Act 233 after a May 8 Court of Appeals split, and who moves parchment between the Senate and House after May 6–7 Supreme Court arguments over nine enrolled bills never presented to the Governor. Alongside that structural fight, the Attorney General logged a rare week of multistate wins — tariffs, consumer tech, opioids, postal firearms rules, and school swatting — while Lansing and MiLEAP advanced quieter but durable regulatory rewrites.
Court of Appeals — Published posture, May 8, 2026
Local-government coalitions challenging October 2024 Michigan Public Service Commission orders implementing the Clean Energy and Jobs Act won a hearing in headlines and a partial scorecard in law: a three-judge panel largely rejected Administrative Procedures Act attacks on the commission’s rulemaking process while agreeing that the commission misread pieces of PA 233 on “affected local unit” inclusion and on compatible renewable energy ordinance notice timing. Energy developers read that as continued statewide siting authority with surgical remand risk; township counsel read it as renewed leverage in the next comment cycle.
MPSC authority to implement PA 233 and proceed with contested large-scale solar, wind, and storage siting pathways described in public reporting.
Narrow holdings faulting definitional and notice-timeline interpretations — the sort of details that rewrite comment letters, not necessarily project maps.
High enough to keep MPSC docket teams in daily email; low enough that Michigan Supreme Court petitions are already budget line items.
Michigan Supreme Court — No. 169381 (post-argument)
Follow-up since the May 3 edition: the rare mandamus fight over nine bills enrolled in the 2024 Legislature but not transmitted to the Governor is no longer a scheduling teaser. Multiple newsroom accounts describe May 6 oral argument in In re Senate of the State of Michigan v. House of Representatives, with counsel framing presentment as a constitutional floor and opposing counsel warning against judicial entanglement in internal chamber logistics.

Michigan Supreme Court — Court rules (material update)
Where last week’s edition tracked reporting on courthouse enforcement, the through-line this week is operative court rules: public accounts describe a Michigan Supreme Court decision adopting language that limits civil arrests at courthouses and in transit to proceedings — a posture that intersects directly with federal immigration enforcement tactics that defense and family lawyers already map on witness diagrams.
Majority described in broadcast coverage as adopting the contested rule package.
Dissent channel preserved in the same reporting — useful for litigants modeling risk on emergency motions.
Attorney General — Multistate litigation
The Department of Attorney General publicized a May 8, 2026 decision from the U.S. Court of International Trade in coalition litigation over presidential tariff authority — the sort of cross-border commercial law development that shows up in manufacturing purchase orders long before it shows up in bar-exam outlines.
Attorney General — Consumer antitrust
State enforcers framed May 5, 2026 as the moment a $700 million multistate settlement with Google over Android app distribution and in-app payment constraints cleared final approval — translating, for Michigan, into consumer restitution mechanics and developer contracting windows worth modeling in platform agreements.
Attorney General — Opioids
The same May calendar that chases tariffs also carries addiction-policy dollars: Michigan’s release describes a May 1, 2026 effective date for a $7.4 billion nationwide resolution with Purdue Pharma and the Sackler family, with structured payments into abatement programs.

Fifteen-year horizon language in the release should travel with every county opioid-abatement spreadsheet this budget cycle.
Attorney General — Federal preemption interface
On May 6, 2026, Michigan joined a multistate comment posture opposing a United States Postal Service proposed rule that would, in the coalition’s telling, allow mailing of concealable firearms in tension with long-standing federal restrictions and state regulatory schemes.
21 states
Opposition framed as protecting state firearms law and postal public-safety history — watch for Administrative Procedure Act comment closure dates and any Michigan-specific enforcement memos from local prosecutors.
Attorney General — Criminal law & schools
A May 1, 2026 release ties a specific East Lansing High School swatting incident to a broader statutory agenda: higher penalties, faster charging templates, and tighter coordination between schools, Michigan State Police, and municipal dispatch.
Michigan Attorney General — East Lansing swatting statement →Governor — Emergency management
Late April snowmelt and rain cycles pushed Governor Whitmer to issue Executive Order 2026-10, declaring emergencies for the Village of Holly and Tuscola County. Municipal lawyers read these instruments for mutual-aid activation, procurement shortcuts, and the interaction between county road commissions and EGLE floodplain messaging.
MiLEAP / LARA — Administrative rules
MiLEAP’s release describes finalized licensing rules for child-care homes aimed at clarity for small providers — the segment of early-education law where zoning variances, fire inspections, and ratio tables collide on a single kitchen island.
Providers should pair the new administrative text with the Child Care Organizations Act (MCL 722.111 et seq.) and local home occupation ordinances.
Expect a burst of LARA communications, insurer questionnaires, and Head Start collaboration agreements over the next comment window.
Governor — April 28, 2026 signings
Not every statutory moment is adversarial: the Governor’s office publicized signings for House Bill 4303 (designating May as Chaldean American Month) and Senate Bill 274 (a US-131 memorial segment for Master Sergeant Gregory T. Kuhse). Immigration and veterans-law practitioners file these as data points in community calendars and highway dedication packets.
Memorial highway designation — coordinate with MDOT signage procurement timelines.
Cultural recognition month — useful for schools, museums, and municipal proclamation drafters.
