Provision for lay members
Sections 77 and 78 of the Commerce Act 1986 provide for lay members to be appointed to the New Zealand High Court for Commerce Act matters.
They ensure that expert evidence on complex competition issues is properly understood, tested and assessed by the High Court.
Appointment of lay members
The Governor-General appoints lay members at the recommendation of the Attorney-General, who is required to consult with the Chief Justice and the Minister of Commerce and Consumer Affairs.
The appointment of lay members to particular cases is at the discretion of High Court Judges.
Once a lay member has been appointed to a case, they become a member of the court for the purposes of that case.
