It was strenuously maintained that both these statutes forbade the raising or keeping on foot a standing army in the kingdom in time of peace, and also the introduction of foreign troops into this kingdom, without the previous consent of Parliament, on any pretence whatever; and that "the fact that Gibraltar and Minorca were detached from these islands did not exclude them from the character of forming a part of the British dominion." And on these grounds Lord Shelburne, who supported Lord Rockingham on an amendment to the address, did not hesitate to denounce this employment of the Hanoverian regiments, as "fundamentally infringing the first principles of our government," and to declare it "high-treason against the constitution." He asked, "if there were a settled plan to subdue the liberties of this country, what surer means could be adopted than those of arming Roman Catholics and introducing foreign troops ?"[53] and compared the measure under discussion to the case of the Dutch regiments of William III., "which the Parliament wisely refused to allow him to retain." In the House of Commons, the Opposition was led by Sir James Lowther and Governor Johnstone, the latter of whom "appealed to the clause in the Act of Settlement which enacted that no person born of other than English parents should enjoy any office or place of trust, civil or military, within the kingdom;" and argued that to employ foreign officers in the protection of a British fortress was to place them in an "office of great military trust." The discussion brought to light strange divisions and weakness in the ministry.

The ministerial lawyers differed on the grounds on which they relied, the Attorney-general, Thurlow, denying that the expression "this kingdom" in the Bill of Rights included the foreign dependencies of the crown[54] (a narrowing of its force which the Chancellor, Lord Bathurst, wholly repudiated), while the argument on which he himself insisted most strongly, that the existence of rebellion in America put end to all conditions which supposed the kingdom to be at peace, could not obtain the support of any one of his colleagues.

But a plea urged by an independent member, Lord Denbigh, was regarded by some of the speakers with greater favor; his contention being that neither the Bill of Rights nor the Act of Settlement had been violated, since both those great statutes must be interpreted with reference to the time at which they were framed, and to the recent acts of James II.

and William III., the recurrence of which they had been designed to prevent, acts to which the present proceeding bore no resemblance.
A stronger justification, however, might have been found in very recent precedents.

In 1745 the ministers had brought over six thousand Dutch troops to re-enforce the army of the Duke of Cumberland, and their act had been subsequently approved by Parliament.
