The Western Australian government has announced the appointment of three new judges, effective from 10 August 2026. Stephen Lemonis will join the Court of Appeal, while Tania Jeyamohan and Steven Wong will become part of the Western Australian Supreme Court. The appointments are seen as a boost to the state's judiciary, with the new judges bringing significant experience in complex matters.

According to Dr Tony Buti, state attorney general, 'All three are highly experienced and respected legal practitioners who have worked on complex matters over their careers and will bolster our State's judiciary at the trial and appellate levels.'

The WA Supreme Court has welcomed the new appointees, with Jeyamohan and Wong set to be formally welcomed at ceremonial sittings. Justice Lemonis takes over from Justice Stephen Hall, who resigned to become deputy commissioner of the Corruption and Crime Commission.

The appointments take effect on 10 August, with any new matters assigned to these judges subject to their expertise in civil and commercial law. Lawyers should note that the new appointees will be handling cases related to complex litigation, commercial disputes, and statutory interpretation.

Justice Lemonis has a long history of practicing at private law firms, focusing on commercial litigation, white collar and corporate crime, regulatory investigations, insolvency, and other criminal proceedings. He has also presided as a judge in the WA Supreme Court's General Division for the last three years.

Tania Jeyamohan brings over 25 years of legal experience to her new role, having served as a District Court registrar and deputy state solicitor for the public and general litigation section at the State Solicitor's Office. She has also practiced in private law firms, focusing on commercial litigation and arbitration.

The appointments of Stephen Lemonis, Tania Jeyamohan, and Steven Wong to the Western Australian courts are significant for several reasons. Firstly, they bring a wealth of experience in complex matters, which will bolster the state's judiciary.

Secondly, their expertise in civil and commercial law will be invaluable in handling cases related to these areas. The appointments also demonstrate the government's commitment to supplementing the judicial resources of the Court of Appeal.

The new judges will take up their positions on 10 August, with Justice Lemonis taking over from Justice Stephen Hall. The WA Supreme Court has welcomed the new appointees and looks forward to working with them.

Lawyers should note that the appointments take effect on 10 August, and any new matters assigned to these judges will be subject to their expertise in civil and commercial law.
