Wardley Australia Ltd & Anor v State of Western Australia

Wardley Australia Ltd and another party appealed to the High Court of Australia against a decision of the Full Court of the Federal Court of Australia. The dispute concerned claims arising under the *Trade Practices Act* and potentially State and common law causes of action, with the Commonwealth Attorney-General intervening on a constitutional issue. The core of the appeal related to the interpretation and validity of limitation periods within the *Trade Practices Act*, specifically section 82, and its application to various claims.

The High Court was required to determine whether section 82 of the *Trade Practices Act* operated as a limitation period for matters rather than specific causes of action, and if so, whether the Commonwealth possessed the constitutional power to enact such a limitation period in relation to State or common law claims heard in the Federal Court's accrued jurisdiction. The appellants argued that if section 82 encompassed State and common law actions, then the Commonwealth's legislative power to do so was questionable.

The Court noted that the constitutional issue, as raised by the intervening Attorney-General, might not ultimately arise in the case. This was because the claims in question were primarily under the *Trade Practices Act*, and any potential invalidity in the Federal Court Rules could be interpreted to exclude State and common law actions, thereby avoiding the constitutional question. The appellants' argument hinged on the interpretation of section 82 as a broad limitation on "matters," which could extend beyond federal claims.
