House Joint Resolution P proposes an amendment to the Michigan Constitution of 1963, specifically amending section 12 of article I. The amendment aims to establish a process for the Michigan Supreme Court to determine whether a state of rebellion or invasion exists, which would justify the suspension of the writ of habeas corpus for public safety. This determination can be initiated by a request from the governor, the attorney general, or through a resolution passed by both chambers of the legislature.

Under the proposed amendment, the Supreme Court is required to make its determination within 48 hours of receiving a request. If approved, this amendment will be submitted to the voters of Michigan during the next general election, allowing the public to weigh in on this significant change to the state's constitutional provisions regarding civil liberties and public safety.
