Federal Court CEO and principal registrar reappointed
The chief executive and principal registrar of the Federal Court of Australia, Sia Lagos, has been reappointed for a period of two years, commencing on 15 May 2025.
Chief Justice of the Federal Court of Australia, Debra Mortimer, has revealed the reappointment of Sia Lagos as CEO and principal registrar of the Federal Court of Australia until 14 May 2027, after which she intends to retire from the role.
Chief Justice Mortimer’s nomination for the reappointment was supported by both Chief Justice William Alstergren, Chief Justice of the Federal Circuit and Family Court of Australia (Division 1) and Chief Judge of the FCFCOA (Division 2), and Kevin Smith, the president of the National Native Title Tribunal (NNTT).
“I have worked closely with Ms Lagos over the last two years on the operations of the Federal Court listed entity and in her role as CEO and principal registrar of the Federal Court. While much has been achieved in a short period of time, there are a number of important ongoing reforms yet to be fully implemented, such as the full implementation across the FCA and the FCFCOA (Divisions 1 and 2) of the digital court management system, CourtPath, and organisational realignment reforms within the Federal Court listed entity to ensure more comprehensive and streamlined provision of corporate services across the three courts and the NNTT,” CJ Mortimer said.
“I determined it was important to prioritise the completion of these projects, which will be best achieved through the continuity of Ms Lagos’ leadership.”
CJ Mortimer remains committed to an “open and transparent process” to secure a new CEO and principal registrar for a five-year term following Lagos’s retirement in 2027.
“I consider Ms Lagos’ reappointment as a very positive outcome. Ms Lagos is well regarded and respected amongst the judges, registrars and staff of the Federal Court, and the staff of the Federal Court listed entity. Her reappointment will enable her to oversee the completion of these important reforms, which, in turn, will improve the way our federal courts and the NNTT administer justice to members of the Australian community,” she said.
“I want to express my appreciation for the significant contribution Ms Lagos has made over the last five years as CEO and principal registrar, and I look forward to continuing to work with her in her role.”
