ruling

The 2nd U.S. Circuit Court of Appeals ruled Wednesday.

U.S. District Judge B. Lynn Winmill did not say in his order when he will make a final decision in the case.

A dissenting justice said the high court's majority ruling avoided the main issue over whether the school can regulate guns on campus.

Oklahoma pursued the case under the state's public nuisance statute.

Two environmental groups and a photographer's association sued to contest the laws.

State and federal officials reacted with disappointment.

Environmentalists praised the ruling but Morris denied their request to halt mining.

The court found last week that a decade-old plan, a 2007 environmental impact statement, was adequate.

The high court ruled the chemicals aren't ingredients necessary to make electricity.

The court has remanded the matter, meaning the lower court will reconsider it in light of the 10th Circuit's findings.
