Practice question
A State accepts that a treaty is valid and in force for it, but invokes an ordinary internal statute as the sole justification for nonperformance. No consent-validity issue under Article 46 is raised. Under Article 27, what is the result?
- Internal law always excuses nonperformance.
- A later domestic statute automatically terminates the treaty internationally.
- Only municipal courts can decide whether international performance is required.
- The State may not invoke its internal law as justification for failing to perform the treaty.
- The treaty binds only private citizens.
