Harper v The Racing Penalties Appeal Tribunal of Western Australia

The case of Harper v The Racing Penalties Appeal Tribunal of Western Australia concerns a dispute over a decision made by the Racing Penalties Appeal Tribunal regarding the administration of a prohibited substance. The Tribunal had found that the applicant had administered a prohibited substance to a horse, leading to penalties. The applicant sought to overturn this decision by applying for prerogative writs, specifically certiorari, on the grounds of error of law on the face of the record and denial of natural justice. One of the key issues was whether the Tribunal had correctly applied the rules regarding the level of prohibited substances, and whether the applicant was denied natural justice by not being allowed legal representation.

The court examined whether the Tribunal had erred in law by not recognising a legitimate expectation regarding the measurement of the prohibited substance. The court found that the expectation relied upon by the applicant was not a procedural undertaking, as required by the principles established in Minister of State for Immigration and Ethnic Affairs v Teoh. The applicant had been aware of the proposed change in the level of uncertainty for detecting the prohibited substance and was given the opportunity to present evidence and arguments against it. The court concluded that the Tribunal's decision on this matter was correct. Another issue was whether the Tribunal had erred in upholding the validity of the rules that barred legal representation before the Stewards. The court found that the rules did not contravene natural justice as the applicant was given an adequate opportunity to present his case and the experts provided substantial assistance.

The court held that the Tribunal's decision was lawful and that the applicant's application for prerogative writs should be dismissed. The court found that the Tribunal had correctly applied the rules and afforded the applicant a fair opportunity to present his case. The argument that the rules barring legal representation were invalid was rejected as the applicant had not demonstrated that this deprived him of natural justice. The court found no merit in the applicant's grounds for the writs and dismissed the application.

The court's final order was to dismiss the application for prerogative writs and to affirm the decision of the Racing Penalties Appeal Tribunal.
