Police Federation of Australia (Australian Federal Police Association Branch) v Commissioner of the Australian Federal Police (on behalf of the Commonwealth)

The Police Federation of Australia (Australian Federal Police Association Branch) brought proceedings against the Commissioner of the Australian Federal Police (on behalf of the Commonwealth) concerning the interpretation of an enterprise agreement. The dispute centred on whether certain salary increases were to be considered "Base Salary" under the agreement. The matter was heard by Judge W J Neville.

The primary legal issue before the Court was to determine the correct construction of the relevant clauses within the enterprise agreement, specifically whether references to "salary increases" were intended to be incorporated into the definition of "Base Salary" or were distinct. The Court was also required to consider the admissibility and utility of extrinsic evidence, namely minutes of prior negotiation meetings, in resolving this interpretive dispute.

Judge Neville found that the minutes of prior negotiation meetings did not assist in construing the agreement, as they referred only to discussions and did not demonstrate any concluded agreement between the parties. The Court observed clear distinctions on the face of the relevant clauses between "Base Salary" and references to "salary increases," noting the absence of any cross-referencing to a "Personal Development Agreement" or "PDA." Consequently, the Court accepted the Applicant's submissions on the single issue in dispute. The parties were directed to notify the Court of the procedural course to be taken, and in the absence of any application within 28 days, no order was made as to costs.
