Unrepresented registered political parties wishing to contest elections for the National Assembly must comply with section 27(1) read with item 3(2) of Schedule 1A of the Electoral Act by submitting both a national list of candidates and at least one regional list of candidates by the deadline in the electoral timetable. Parties must also meet quota requirements for verified voter supporter signatures as prescribed by section 27(2)(cB) and the regulations. Non-compliance with these peremptory requirements results in disqualification by operation of law (ex lege), not by administrative decision. Section 28 of the Electoral Act does not vest the Electoral Commission with discretion to condone late submission of candidate lists or supporter lists, but only allows rectification of limited failures in respect of sections 27(2)(a), (b), (cA), (d) or 27(4) for parties that have already submitted lists in compliance with sections 27(1) and 27(2)(cB). The Electoral Commission has no inherent power to condone failure to comply with peremptory requirements absent express statutory discretion. In motion proceedings involving factual disputes, the Plascon Evans principle applies: where the respondent's version is not so far-fetched or untenable that it can be rejected out of hand, and is more probable than the applicant's unsubstantiated assertions, it should be accepted.
