In Re Application of Enbridge Energy to Replace and Relocate Line 5

Summary

The Michigan Supreme Court held that MEPA decisions are reviewed de novo, that the PSC must consider whether the Replacement Project will proximately cause Line 5’s extended operation, must conduct a consistent alternatives analysis, and must evaluate impacts on public‑trust resources. Accordingly, it reversed the Court of Appeals, vacated the PSC’s approval, and remanded for further proceedings.
