The binding legal principles established are: (1) Amendments to the SADC Treaty are adopted by decision of three-quarters of the Summit and enter into force immediately upon adoption without requiring ratification by individual Member States. (2) The Protocol of the SADC Tribunal, as amended, forms an integral part of the SADC Treaty and binds Member States without requiring separate ratification. (3) Foreign judgments, including decisions of international tribunals, may be recognized and enforced under Zimbabwean common law even in the absence of specific statutory provision, provided the general requirements for recognition are met. (4) A foreign judgment cannot be recognized and enforced if it is contrary to public policy, conflicts with an overriding statute, or was obtained without observance of principles of natural justice. (5) The Constitution of Zimbabwe is supreme, and to the extent that enforcement of a foreign judgment would require the Government to act in a manner manifestly incompatible with constitutional provisions, such enforcement is contrary to public policy and must be refused. (6) Public policy at the municipal level must be assessed with reference to both domestic law (including the supremacy of the Constitution) and international obligations, but where there is direct conflict, the Constitution prevails. (7) While a State cannot invoke domestic law to absolve itself from international obligations at the international level, at the municipal level, courts must apply and uphold the Constitution as supreme law.
