The Act specifies those decisions of the Minister or the Director, NICNAS that may be taken before the Administrative Appeals Tribunal (AAT). Appealable matters include decisions on confidentiality, inventory listing, new and existing chemicals assessments and NICNAS registration decisions.

Two applications involving three appellants were made to the AAT during 2005-06. This compares with no applications being made to the AAT in 2004-05, 2003-04 or 2002-03, and four in 2001-02. There has been a total of nine appeals against the Director's decisions since the introduction of the Scheme in 1990, with five withdrawn, two found in favour of NICNAS. Two decisions remained pending at 30 June 2006.
