NWCB and National Disability Insurance Agency

This matter concerned requests made by the National Disability Insurance Agency (NDIA) to be released from an implied undertaking regarding the use of documents in proceedings before the Administrative Appeals Tribunal (AAT). The applicant in the primary proceeding was NWCB. The Deputy President, S A Forgie P, considered the nature of the implied undertaking and the circumstances under which it could be waived by the Tribunal.

The central legal issue was whether the NDIA was subject to an implied undertaking not to use documents obtained for the purposes of the AAT proceedings for other purposes, and if so, whether the Tribunal had the power to waive that undertaking. Specifically, the Tribunal had to determine the scope of Part 5 of the General Practice Direction made under s 18B of the Administrative Appeals Tribunal Act 1975, and whether the production of certain documents was compelled in a manner that would attract an implied undertaking.

The Deputy President reasoned that an implied undertaking not to use documents for purposes beyond the litigation only arises when the production of those documents is compelled. In this instance, the Deputy President found that for several of the documents for which the NDIA sought release from an implied undertaking, the NDIA was not subject to such an undertaking because the documents were not produced under compulsion for purposes outside the proceedings. Consequently, the requests for waiver in relation to those specific documents were refused. However, for other documents, the Deputy President granted the NDIA's request to be released from an implied undertaking, permitting their use for assessing the applicant's entitlements under the NDIS Act.
