Incorporation of foreign and international
rules and principles will require skills of synthesis and distinguishing that are
distinct from traditional domestic legal reasoning, and they may require appreciation of important differences in foreign / international legal, political, or perhaps even cultural context.63 International legal
rules often play a complex role in domestic law, presenting issues of interpretation and enforceability that do not easily fit within traditional domestic United States legislative, administrative, and
judicial legal structures.64 Integration or application of
rules from foreign nations may be even more complex, especially where those systems are substantially different from our own.65 Additionally, there may be discrepancies between the form and function of foreign or international law that affect their proper application.
