Commissioner of Police v Hatfield

The Commissioner of Police appealed to the New South Wales Court of Appeal against a decision of the Supreme Court of New South Wales which had granted an injunction restraining the Commissioner from taking certain disciplinary action against Detective Sergeant Hatfield. The dispute concerned the Commissioner's proposed disciplinary proceedings against Detective Sergeant Hatfield, which Hatfield alleged were unlawful.

The central legal issue before the Court of Appeal was whether the Commissioner had acted unlawfully in initiating disciplinary proceedings against Detective Sergeant Hatfield. Specifically, the court had to determine if the Commissioner's actions were tainted by bias or improper purpose, thereby rendering the proceedings invalid.

The Court of Appeal found that the Commissioner had indeed acted with bias and for an improper purpose in initiating the disciplinary proceedings. The court reasoned that the Commissioner's stated intention to "get rid of" Detective Sergeant Hatfield, coupled with his involvement in the decision to charge Hatfield, demonstrated a pre-determined outcome and a lack of genuine consideration of the evidence. This conduct was found to be contrary to the principles of administrative law, which require decision-makers to act fairly and impartially. The court applied the principles established in cases concerning bias and the abuse of power in administrative decision-making.

Consequently, the Court of Appeal dismissed the Commissioner's appeal and affirmed the Supreme Court's decision, upholding the injunction that restrained the Commissioner from proceeding with the disciplinary action.
