Artificial Intelligence law at Guam (US)
Guam, an unincorporated territory of the United States, has a hybrid legal system influenced by U.S. federal law, Guam’s own statutes, and judicial precedents from the Supreme Court of Guam, the Superior Court of Guam, the Ninth Circuit Court of Appeals, and in some cases the U.S. Supreme Court.
1. Sources of Law
Guam’s jurisprudence draws from:
The Organic Act of Guam (1950) – the territory’s foundational governing document.
Guam Code Annotated (GCA) – statutory law enacted by the Guam Legislature.
Federal law – applicable unless explicitly inapplicable to unincorporated territories.
Case law – judicial decisions by Guam’s courts and federal courts with jurisdiction.
2. Role of Precedent
Guam follows a common-law model, which means:
Decisions of the Supreme Court of Guam are binding on all lower courts.
When Guam law is silent, courts may rely on California law, common law, or persuasive federal authority, depending on context.
Before 1996 (when Guam created its own Supreme Court), Ninth Circuit decisions exercised appellate authority; they remain persuasive but not binding now.
3. Key Themes in Guam Jurisprudence
Common recurring themes in Guam case law include:
Autonomy vs. federal oversight
Criminal procedure rights (search/seizure, evidence, due process)
Interpretation of the Organic Act
Territorial application of federal statutes
Sentencing discretion and proportionality
Traditional Chamorro customs and their legal relevance
