Paterson v O'Brien

The High Court of Australia considered a dispute between Paterson and O'Brien concerning the validity of a notice to produce documents. The core of the disagreement lay in whether the notice, issued under the *Royal Commissions Act 1902* (Cth), was sufficiently specific in its description of the documents sought.

The central legal issue before the Court was the interpretation of section 6(1) of the *Royal Commissions Act 1902* (Cth), which governs the scope and validity of notices to produce documents issued by a Royal Commissioner. Specifically, the Court had to determine whether the notice in question provided adequate particularity to satisfy the requirements of the Act, and consequently, whether it was legally enforceable.

The Court reasoned that a notice to produce under the Act must describe the documents sought with a degree of particularity that enables the recipient to identify them without undue difficulty or the need for extensive interpretation. While absolute precision may not always be achievable, the description must be sufficiently clear to avoid ambiguity and prevent the notice from being a "fishing expedition." The Court found that the notice in this instance lacked the necessary specificity, rendering it invalid. The orders made reflected this finding.
