Not being a lawyer, I had to look up what "heads of bench" meant. So for anyone else watching who had no idea, each court is headed by a senior judge, usually described as the Chief Judge or Principal Judge of that court, and those positions are often referred to as heads of bench. In this country this also includes the Chief Judge of the Māori Land Court in respect of both the Māori Land Court and the Māori Appellate Court. So those heads of bench have administrative responsibilities in relation to the court but no direct authority or responsibility over the judicial work of the judges.
