The binding legal principles established include:
1. Constitutional Principles must be interpreted purposively, teleologically, holistically, and consistently with each other, not with technical rigidity.
2. The test for compliance is whether provisions of the new constitution are inconsistent with any Constitutional Principle and whether they give effect to each and all of them.
3. Where a constitutional provision bears multiple reasonable meanings, one consistent with the Constitutional Principles and one inconsistent, courts must adopt the interpretation that makes it consistent. Such certification-based interpretations should not be departed from "save in the most compelling circumstances."
4. "Universally accepted fundamental rights" (CP II) refers to rights recognized in open and democratic societies as inalienable entitlements of human beings, requiring "wide measure of international acceptance" but not absolute universality.
5. "Entrenched" rights (CP II) require more stringent protection than ordinary constitutional provisions—not merely protection from ordinary legislation but additional safeguards such as special majorities, involvement of both houses, or other reinforcing mechanisms.
6. "Special procedures involving special majorities" (CP XV) requires both procedural safeguards and supermajorities for constitutional amendments, not merely supermajorities alone.
7. Separation of powers (CP VI) does not require absolute separation; some overlap of personnel between legislature and executive is permissible. What matters is functional separation and appropriate checks and balances ensuring accountability, responsiveness, and openness.
8. Independence and impartiality of constitutional institutions (CP XXIX) must be both "provided for and safeguarded"—requiring adequate removal procedures beyond simple legislative majorities for watchdog institutions like the Public Protector and Auditor-General.
9. Under CP XVIII.2, provincial powers and functions are "substantially less than or substantially inferior" when a holistic weighing of all relevant factors (collective provincial power through the second chamber, individual provincial powers, legislative competences, executive authority, fiscal arrangements, and override mechanisms) demonstrates meaningful diminution across multiple areas, even if some individual powers remain unchanged.
10. Constitutional supremacy (CP IV) prohibits ordinary legislation being immunized from constitutional review unless it is incorporated into the constitution itself and made subject to constitutional amendment procedures.
11. Framework requirements (e.g., for local government under CP XXIV) require more than merely listing categories—they demand an "overall structural design or scheme" establishing broad parameters within which detailed implementation occurs.
