Congressional Oversight of the Antiquities Act

This bill (S 2820) would amend the Antiquities Act to impose time limits on national monument designations. It requires that any new national monument or land reservation under the Act expire 6 months after creation unless Congress passes a new law extending it. If a monument expires without extension, the same land cannot be re-designated as a national monument for 25 years. This directly affects the President’s authority to establish monuments under the Antiquities Act and limits the permanence of such designations without congressional action.
