Study notes for Riggins v. McCarthy: professor notes, cold call prep, exam angles, and memory aids.

States must aim to conform to international treaty obligations, but the federal government is responsible for ensuring compliance.
Professor Notes

In Riggins v. McCarthy, the Supreme Court addressed the complex interaction between state and international law, particularly in the environmental context. The Court emphasized the principle that while states have a role in adhering to international obligations, the ultimate responsibility for ensuring compliance with such treaties rests with the federal government. This case serves as an important example of the federalism principle in U.S. law, where states cannot independently act in a manner that undermines federal treaty obligations, yet they are not strictly bound by international agreements unless expressly incorporated into domestic law.

The decision also highlights the need for clarity in how states approach environmental legislation when it conflicts with international agreements. The Court did not invalidate the state law outright but instead reinforced the notion that states should work in concert with federal objectives to fulfill treaty goals. This case is critical for understanding the scope of state powers versus the federal government's authority in matters governed by international law, particularly in an era of rising environmental concerns.
