AISG procedure hypo: D moved to suppress evidence under both the 4th Amendment and the analogous search and seizure provision of the Michigan Constitution. The highest court in the state ruled that the search was illegal but it did no make clear whether it was illegal as a matter of state law or federal law, or both. The Supreme Court took the case, reviewed the federal issue, found that the search was valid, and that the evidence could lawfully be used under the 4th Amendment. What does the Supreme Court do next?
Remand the case to the Michigan Supreme Court, so that the court can reconsider whether the search was lawful under the state constitution.
