Challenging the result on the grounds of disqualification
There is a separate judicial process for challenging the election of an MP on the grounds that they were or are disqualified under the House of Commons Disqualification Act 1975 (as amended). In that case, an application may be made to the Privy Council for a declaration to that effect (provided that a petition is not pending or has been tried in which the alleged disqualification is or was in issue (and where the grounds for the disqualification applied at the time of the election) or an Order of the House of Commons to disregard the disqualification has not been made).1
Any person may apply to the High Court for a declaration that a Member of Parliament is, or at any time since being elected has been, disqualified from being a Member of Parliament.2
Any person considering applying for a judicial declaration of disqualification should seek their own legal advice.
