O'Sullivan v Noarlunga Meat Ltd (No 2), was a High Court of Australia case, in which a certificate, under s 74 of the Australian Constitution, was sought for leave to appeal to the Privy Council against the previous decision of O'Sullivan v Noarlunga Meat Ltd. Dixon CJ, Williams, Webb and Fullagar JJ wrote a joint judgment refusing a certificate of appeal stating that the policy of section 74 was to confine the decision of essentially federal questions to the High Court. McTiernan, Kitto and Taylor JJ each delivered concurring judgments.
