Firstly, welcome. Not much action here these days - were all waiting for the Court decision and news of the C-O commencement of production. 

My understanding is that either party can request a decision of the District Court be reviewed by the Court of Appeals. But that request cannot be frivilous. There must be grounds for the review - either they were treated unfairly, the wrong law was applied, or the law was applied wrongly.

I doubt Bartell or the Tribes would ask for a review (no grounds, legal costs).

The "environmentalists" have in the past acknowledged that ultimately the mine will proceed, and all they are doing is delaying commencement of construction. If they thought a review would further delay the mine, they would likely go down that path (i.e. claiming the law was wrongly applied). Legal costs don't seem to be a constraining factor for them. Ofcourse the Court of Appeals can decide against reviewing the case - again there must be proper grounds for the review, and those grounds cannot be frivilous.

All in my opinion.
