"I am looking forward to continuing to provide, along with the staff of Gordon Pilditch, the excellent service to the Crown that has been provided for the last eight years under Fletcher Pilditch."
Mr Pilditch said he was delighted but not surprised at Ms Gordon's appointment.
"Amanda and I formed this firm to support my role as Crown Solicitor and she has been an integral part of both the organisational and legal success of the firm.
"She and I have worked closely on many cases together and she will bring great legal knowledge, skill and judgment to the role.
"I am very happy to be leaving this responsibility in her very capable hands."
