- The Nigerian legal hierarchy places the Constitution and Acts of the National Assembly above institutional guidelines from bodies like INEC. - A recent High Court judgment by Justice Umar ruled that INEC acted 'ultra vires' by attempting to vary statutory timelines defined in the Electoral Act. - While the ruling allows for potential supplementary candidate lists, political parties face significant risks of disqualification if the judgment is overturned on appeal. - Courts are increasingly intervening in 'internal party affairs' when fundamental rights or constitutional breaches occur, challenging the notion of party immunity. - The stability of the 2027 election cycle depends on INEC's adherence to the Electoral Act rather than administrative convenience.
