Murphy Company, et al. v. Joseph R. Biden, Jr., President of the United States, et al.

The Antiquities Act of 1906 authorizes the President, “in [his] discretion,” to declare that “historic landmarks, historic and prehistoric structures, and other objects of historic or scientific interest” found on federal land are “national monuments” and to “reserve parcels of land as a part of the national monuments” so long as those parcels are “confined to the smallest area compatible with the proper care and management of the objects to be protected.” 54 U.S.C. 320301. Three decades after that Act’s passage, in the Oregon and California Railroad and Coos Bay Wagon Road Grant Lands Act of 1937 (O&C Act), Congress reserved certain federal lands in Oregon for “permanent forest production,” mandating that “the timber thereon shall be sold, cut, and removed in conformity with the princip[le] of sustained yield” timber production. 43 U.S.C. 2601. In 2017, President Obama invoked the Antiquities Act to add O&C Act timberlands to an existing Oregon national monument established to protect biological diversity, see Proclamation 9564, 82 Fed. Reg. 6,145 (Jan. 12, 2017)—despite the fact that lands that are part of that monument may not be used in “provision of a sustained yield of timber,” Proclamation 7318, 65 Fed. Reg. 37,249, 37,250 (June 9, 2000). The question presented is whether the Antiquities Act authorizes the President to declare federal lands part of a national monument where a separate federal statute reserves those specific federal lands for a specific purpose that is incompatible with national-monument status.
