For decades, the U.S. Forest Service has said it can’t say “no” to a mine on its land.

Now, the recent federal court ruling overturning approval of the Rosemont Mine on service land near Tucson will make it harder for the Forest Service to say “yes.”

Legal experts say U.S. District Judge James Soto’s July 31 ruling, if upheld in higher courts, will have national repercussions.

They’re using words like “chaos,” “shocking” and “blockbuster” to discuss the ruling’s ramifications.

The ruling could chill the hard-rock mining industry that has lived under a generally favorable legal climate since Congress passed the 1872 Mining Law to encourage mineral exploration of public lands.

Mining industry lawyers say the ruling usurps the role of government agencies in making such decisions, could bring chaos to federal mining reviews and will add more delays in permitting to an industry already having some of the longest permit times for new mines in the Western world.

Environmental law professors say the ruling is well-grounded factually and could end a century-old practice by mining companies of skirting or dodging federal law by dumping mining wastes on federal lands without proper reviews.

They say it also exposes what they see as the fallacy of having our public-lands mining governed by a law written at a time when picks and shovels were used to pull minerals from the ground.

Soto’s order is “likely the most significant federal court decision on federal mining law in several decades,” mining industry lawyers James Allen and Michael Ford of the Phoenix-based law firm Snell and Wilmer wrote in an online article.
