The Saskatchewan Court of Appeal has upheld a ruling against a First Nation that wants to halt oilsands exploration on what it calls its traditional territory.

Last year a Court of Queen's Bench judge ruled against the Buffalo River Dene Nation's challenge of exploration permits issued to Scott Land and Lease.

The First Nation had argued the permits were a violation of treaty rights and the policy of duty to consult was ignored.

At the time, the judge in the case ruled there is no duty to consult for exploration permits.

The Buffalo River Dene then filed an appeal.

In a ruling released Thursday Justice J. A. Caldwell dismissed the court action.
