[Clark] circulated his own draft constitution bill. This was practically a transcript of relevant provisions from the British North American Act, the United States Constitution and the Federal Council Act, arranged systematically, but it was to be of great use to the drafting committee at the convention. Parkes received it with reservations, suggesting that 'the structure should be evolved bit by bit'. George Higinbotham admitted the 'acknowledged defects & disadvantages' of responsible government, but criticized Clark's plan to separate the executive and the legislature. Clark's draft also differed from the adopted constitution in his proposal for 'a separate federal judiciary', with the new Supreme Court replacing the Privy Council as the highest court of appeal on all questions of law, which would be 'a wholesome innovation upon the American system'. He became a member of the Constitutional Committee and chairman of the Judiciary Committee. Although he took little part in the debates he assisted (Sir) Samuel Griffith, (Sir) Edmund Barton and Charles Cameron Kingston in revising Griffith's original draft of the adopted constitution on the Queensland government's steam yacht, Lucinda; though he was too ill to be present when the main work was done, his own draft had been the basis for most of Griffith's text. Clark's supporters are quick to point out that 86 Sections (out of a total of 128) of the final Australian Constitution are recognisable in Clark's draft, and that "only eight of Inglis Clark’s ninety-six clauses failed to find their way into the final Australian Constitution"; but these are potentially misleading statistics. As Professor John Williams has pointed out:It is easy to point to the document and dismiss it as a mere ‘cut and paste’ from known provisions. While there is some validity in such observations it does tend to overlook the fact that there are very few variations to be added once the basic structure is agreed. So for instance, there was always going to be parts dealing with the executive, the parliament and the judiciary in any Australian constitution. The fact that Inglis Clark modelled his on the American Constitution is no surprise once that basic decision was made. Issues of the respective legislative powers, the role of the states, the power of amendment and financial questions were the detail of the debate that the framers were about to address in 1891.As to who was responsible for the actual detailed drafting, as distinct
