SALT LAKE CITY -- The state of Utah filed a lawsuit Friday against the federal government over an Obama administration plan to make millions of acres of undeveloped land in the West eligible for federal wilderness protection.Utah Gov. Gary Herbert called the plan a "midnight ambush." He agreed that wilderness areas deserve protection but said the federal policy circumvents state efforts to determine what areas should be deemed wilderness and whether it would harm Utah's economy.Herbert, a Republican, said he hoped Alaska, Idaho and Wyoming would soon join the lawsuit. The three states also have Republican governors. A spokesman for the Wyoming attorney general's office said the state is considering its options.
