It was provided also, that the king might erect Van Diemen's Land into a separate colony: confer on the acting-governor, in the absence of the governor-in-chief, the various powers conveyed by the act; and, in that case, terminate the dependence of the supreme court on the court of New South Wales. On these extensive powers the checks provided were the requisite preliminary certificate of the chief justice, that the ordinances proposed were consistent with the laws of England, or the circumstances of the colony; the exposure of these acts on the table of the House of Commons; the obligation of the governor to show cause for the act passed in defiance of his council; the prohibition of direct taxation, except for local purposes: guarantees of little value at the time of their adoption, but rendered of greater importance by the growth of freedom in the empire at large. The act of parliament did not pass without animadversion and discontent. Sir James Mackintosh moved that a jury of twelve should be substituted for the clause constituting a military jury--the most obnoxious portion of the bill. In this he was seconded by Mr. Wilberforce, but the proposition was defeated by a majority of eleven. Mr. Canning recommended a compromise between the friends and opponents of the bill, by limiting its duration to five years, and to this the minister assented. The capacity of the colonies to furnish jurors was long a subject of debate, Mr. Justice Bent stated, that after full consideration he recommended a grand and a common jury, in conformity to the English law, and the trial of convicts by the police;[138] but Commissioner Bigge pronounced against the scheme, and was confirmed in his opinion by the leading colonists of the time. The whole state of society opposed serious objections to its adoption, and it was scarcely practicable in Van Diemen's Land. The settlers were generally desirous that Van Diemen's Land should be erected into a separate colony. To this, Sorell was opposed. He thought the measure premature: tending to augment the expenses of government; to deprive the people of the advantages of an appeal to the elder colony, and of participation in that more liberal system of government a larger community could demand. A public meeting was, however, summoned, and a petition adopted by acclamation. The sole dissentient present, Mr. Murray, was roughly treated by the petitioners. The nearer inspection of a chief authority, and the more ample means possessed for good, were its advantages; but it occasioned a more rigid separation in social life, multiplied offices which might have been long confined to the elder colony, and removed too far the governor and courts from effectual oversight and appeal. The colony was not sufficiently consolidated to oppose a force of public opinion to the despotic tendencies of the new constitution.
