The Minnesota Supreme Court's decision to rescind PolyMet's permit to mine in essence, returned both mining and environmental advocates to their respective corners - but both are claiming victory.
PolyMet is hoping they can avoid hearings on the "upstream" mine waste dam and its majority owner, Glencore.
But environmentalists, who have found problems with additional project permits since 2018 are hoping this is a good place to stop, reassess and ask the hard question: Can this project move ahead legally at all?
