The binding legal principles established are: (1) Parliamentary freedom of speech guaranteed by sections 58(1)(a) and 71(1)(a) of the Constitution can only be limited by the rules and orders of the relevant House, not by Acts of Parliament; (2) This is because the rule-making power in sections 57(1) and 70(1) is wholly internal to Parliament, whereas Acts of Parliament involve Executive participation through Presidential assent, bill referral powers, and legislative initiation, which would impermissibly involve an external arm of state in limiting parliamentary speech; (3) The word 'person' in section 11 of the Powers, Privileges and Immunities of Parliament and Provincial Legislatures Act 4 of 2004, when interpreted in accordance with ordinary grammatical meaning, the context of the Act as a whole, and the purpose of the section, includes members of Parliament; (4) Section 11, insofar as it applies to members, is constitutionally invalid because it infringes both the privilege of freedom of speech and the immunities from arrest and criminal proceedings; (5) The term 'disturbance' in section 11 should be narrowly construed to mean only conduct that hamstrings and incapacitates Parliament from conducting its business with no reasonable prospect of resumption within a reasonable time, to avoid overbreadth that would capture legitimate robust parliamentary debate; (6) When constitutional interpretation principles permit reading-in as a remedy, courts should interfere as little as possible with legislation while ensuring constitutional compliance.
