LOOK A LITTLE CLOSER

Article I, Section 8, Clause 10b

Offenses against the law of nations

Current text
and Offenses against the Law of Nations;

What it means

Congress may define and punish offenses against the law of nations. The phrase refers to legal obligations governing relations among nations and certain internationally recognized wrongs.

Historical setting

Federalist 42 argued that the Union needed means to address violations that could create conflict with foreign powers. Leaving such matters entirely to separate states could expose the whole country to consequences of local failure.

What it does

The provision gives Congress a legislative role in specifying offenses and penalties. It should be distinguished from a claim that every international norm automatically creates a domestic criminal offense without implementing law.

Debate & interpretation

The scope of the underlying law and Congress’s authority to define it can generate disagreement. A useful analysis separates whether a norm exists internationally, whether Congress legislated about it, and whether the particular application is constitutionally authorized.

A common misreading

The clause does not mean that every contested statement of international policy becomes an enforceable federal crime.

Think it through

Why should one state’s treatment of foreign representatives or international obligations concern the entire Union?
