15.4 Global influences on Supreme Court jurisprudence

The Supreme Court's jurisprudence is increasingly influenced by international law and foreign legal systems. Treaties, customary international law, and general principles shape the Court's approach to human rights, criminal justice, and environmental regulations. Notable cases like Roper v. Simmons and Lawrence v. Texas demonstrate this global perspective.

Comparative constitutional analysis examines foreign legal systems to inform U.S. constitutional interpretation. This approach provides context for evolving standards and identifies shared values across legal systems. Landmark cases like Atkins v. Virginia and Washington v. Glucksberg have employed comparative analysis, sparking debate on the role of foreign law in U.S. courts.
