Provisions of internal law regarding competence
to conclude treaties
1. A State may not invoke the fact that its consent to be bound by a treaty has been expressed in
violation of a provision of its internal law regarding competence to conclude treaties as invalidating its
consent unless that violation was manifest and concerned a rule of its internal law of fundamental
importance.
2. A violation is manifest if it would be objectively evident to any State conducting itself in the
matter in accordance with normal practice and in good faith.
