New Zealand had not yet obtained responsible government, and so the 1st Parliament did not hold any significant power. The 1st Parliament was held before the creation of either political parties or the office of Premier. There were, however, appointments made to the Executive Council. From 14 June 1854 to 2 August 1854, there was a four-person cabinet, New Zealand's first ministry, led by James FitzGerald, with Henry Sewell, Frederick Weld, and Thomas Bartley. Then, from 31 August 1854 to 2 September 1854, there was another four-person cabinet led by Thomas Forsaith, with James Macandrew, William Travers, and Jerningham Wakefield. Some historians consider FitzGerald and Forsaith to be New Zealand's first Prime Ministers, but neither held any formal leadership role, and since "responsible government" had not yet been obtained, they had little real power. Henry Sewell, appointed shortly after the 2nd New Zealand Parliament opened, is more often considered to have been the first Prime Minister. On 17 August 1854 when the newly convened House of Representatives met, Governor Wynard was proposing to prorogue the General Assembly as he had not received authority from London. Sewell wanted to continue debate and the suspension of standing orders was moved. The minority "Wakefieldites" opposed the move, and tried to leave so that there would not be two-thirds of members present. This led to a violent turn when Sewell was reported to have pounced on the member for Nelson James Mackay and seized him by the throat. Suspension was moved an hour later when some members of the absent majority returned. Mackay was later found guilty of gross and premeditated contempt. There were moves to find the member from Dunedin James Macandrew guilty of contempt for entering the house with his hat on, but this was withdrawn. The 1st Parliament consisted of thirty-seven representatives representing twenty-four electorates. Two regions of the colony were not part of any electorate, and so were not represented.
