ACC sought leave to appeal the Langhorne decision.

However ACC agreed and the High Court has now directed that ACC complies with the procedural ruling of the Accident Compensation appeal authority.

Quote:
that the effect of s 391(1) and (4) of the 2001 Act, was to require that decisions made under the 1972 and 1982 Acts, as applied by the 2001 Act, are to be determined in accordance with Part 9 of the 1982 Act.


Accident Compensation Corporation v Langhorne HC Auckland CIV 2011-404-415 [2011] : (Judgements - Case Law - High Court of New Zealand)

Long term claimants whose cases fall under the 1982 act and who have been denied access to appeal/review or whose reviews have been determined under the 2001 act must consider that they now have grounds to apply for a late review on the basis that their cases were heard by the wrong Jurisdiction.
