National Monuments

Heidi McIntosh, Managing Attorney, Rocky Mountain Office, Earthjustice: "The Antiquities Act was really a one-way designation authority that allows the president to designate monuments, but it doesn't grant the president any authority to reverse the designations of his predecessors. When [the president] exercises his power, he's standing in the shoes of Congress. In the same way a president can't, on his own, mend or revoke acts of Congress, he can't go back and amend or revoke monuments, either."
