Except in exceptional circumstances (such as those in Martin v A-G & Anor where a lower court wrongly refuses to refer a constitutional matter), any constitutional issue that arises during proceedings in a lower court must be brought to the Constitutional Court only upon referral by that lower court in terms of section 175(4) of the Constitution. Section 85(1)(a) of the Constitution, which permits persons to approach 'a court' alleging violation of fundamental rights, must be interpreted consistently with section 175(4) and should not be read literally to permit litigants to abandon ongoing proceedings in lower courts and approach the Constitutional Court directly. The Legislature is presumed not to intend absurdity, and where a literal interpretation would create disorder, inconsistency with other provisions, or undermine established common law principles of judicial comity, courts must adopt a purposive interpretation that avoids such consequences. Constitutional provisions dealing with the same subject matter should be interpreted coherently, and later provisions should be read in light of earlier provisions addressing the same subject.
