}} In appealing the decision to the Privy Council, the Commonwealth adopted a deliberate strategy of limiting the grounds of appeal to avoid seeking a certificate from the High Court under
section 74 of the Constitution. The case was argued for 37 days before the Privy Council, one of the longest in its history, during which two of the Lordships assigned to the case (
Lord Uthwatt and
Lord du Parcq) died. The Privy Council endorsed the High Court decision in adopting the individual rights approach. Provisions of the Commonwealth law prohibited private banks from carrying out interstate business banking. Interstate banking transactions under the law were thus not "absolutely free" and hence in violation of Section 92 of the Constitution. The Law Lords held that a simple legislative prohibition of interstate trade and commerce would be constitutionally invalid, but a law seeking to regulate or prescribe rules as to the manner of trade and commerce would not necessarily be in breach of section 92. The Board noted that the question of whether a law was merely regulatory or unduly discriminatory "will often be not so much legal as political, social or economic. Yet it must be solved by a court of law." Additionally, while rejected this nationalisation by the government, the Board left the door open to future takeovers where "on its own facts and in its own setting of time and circumstances ... prohibition with a view to State monopoly was the only practical and reasonable method of regulation".
