Whether Montana's higher fees and mandatory combination license for nonresident elk hunters violated the Privileges and Immunities Clause of Article IV.
Holding
No. Recreational elk hunting is not a fundamental privilege or immunity protected by Article IV, so Montana may favor residents in access to that activity.
Reasoning
The Privileges and Immunities Clause promotes interstate comity by preventing States from discriminating against citizens of other States with respect to privileges bearing on the Nation's vitality as a single Union. The Court's precedents protect such matters as pursuing a common calling, owning and transferring property, and obtaining access to state courts. But the Clause does not forbid every distinction between residents and nonresidents; some distinctions properly reflect the Nation's structure as a union of separate States.
Nonresident elk hunting was a recreational sport, not a means of livelihood or an incident of travel, trade, or another essential national activity. It was costly, pursued for sport and trophies, and available only to those able or willing to bear substantial expense. The nonresident hunters were not excluded from Montana, denied employment, or prevented from pursuing a commercial occupation.
Montana's elk herd was a finite resource requiring conservation and careful management. Although the older idea that a State literally owns its wildlife is a legal fiction, it still reflects the State's important interest in preserving and regulating wildlife for its people. Because equal access to recreational elk hunting is not basic to the maintenance or well-being of the Union, the Clause did not require Montana to give nonresidents the same access terms as residents.
