The binding legal principles established are: (1) Provincial constitution-making power under section 104(1)(a) read with section 143 is subject to strict limitations - provinces cannot alter their character or relationship with other levels of government established by the national Constitution; (2) 'Legislative or executive structures and procedures' in section 143(1)(a) means the form, composition and organisation of provincial institutions ('structures') and the manner in which they exercise their powers ('procedures'), not the substance of legislative or executive powers themselves, which are exhaustively provided for in the national Constitution; (3) An electoral system is not a 'legislative structure or procedure' within the meaning of section 143(1)(a) - it determines selection of representatives but does not affect the constituent elements of the legislative structure itself; (4) Provinces cannot, through provincial constitutions, impose duties on or remove duties from judicial officers or other functionaries who are not provincial functionaries and are independent; (5) Where the national Constitution establishes uniform standards (such as prohibition on 'paid work' for executive council members), provinces cannot delegate to provincial legislation the power to define or alter those standards; (6) Provincial constitutional provisions that are inchoate and depend on future provincial legislation for their content cannot be certified as they lack the finality required by the certification process; (7) Provinces may provide for matters appropriate to a provincial constitution that do not impinge upon competences of other levels of government and are not inconsistent with the national Constitution, including provincial symbols and honours, directive principles of policy (if non-justiciable), and certain naming conventions; (8) Repetition in provincial constitutions of national constitutional provisions is permissible where those provisions relate directly to governance within the province and are necessary for coherence and comprehension of the provincial constitution; (9) The test for inconsistency is whether provisions 'cannot stand at the same time' - they are not inconsistent when it is possible to obey each without disobeying either; (10) Different 'structures and procedures' must be provided for in the provincial constitution itself and cannot be delegated to ordinary provincial legislation, as they are subject to special voting procedures (two-thirds majority) and certification requirements.
