Supreme Court allows appeal from Court of Appeal, and: (a) determines that a prospective electoral candidate had locus standi to challenge the constitutional validity of legislation that limited public funding to political parties where they failed to meet a 30% quota of female and 30% of male candidates, and where the candidate had been excluded from consideration by his political party because he was not a woman, on the grounds that his interests had prima facie been affected by the legislation in question; and (b) remits the matter to the High Court for full hearing on its merits.
