The state of Wyoming has three million acres of national forest.
A United States supreme court decision now ensures that those three million acres will be protected from development, including logging, mining and drilling.
While Governor Matt Mead is disappointed in the decision. He says it's time to move on.
"I think that effectively ends the litigation on that case for the state of Wyoming so now we are, of course, going to be working with the forest service to try to do the best we can understanding that's the rule of law," Mead said.
There are exceptions to the rule in matters of public safety to allow logging to protect forests from severe wildfires.
The "Roadless Rule" as it's become known as, has faced years of legal battles since it's inception in 2001.
A challenge filed by Alaska is the last remaining legal battle that is still pending in the Supreme Court.
