the house of March, he devised this claim, which was preferred in the vacancy of the throne, Richard's cession, having been read and approved in parliament, and the sentence of deposition, "out of abundant caution, and to remove all scruple," solemnly passed by seven commissioners appointed out of the several estates. "After which challenge and claim," says the record, "the lords spiritual and temporal, and all the estates there present, being asked, separately and together, what they thought of the said challenge and claim, the said estates, with the whole people, without any difficulty or delay, consented that the said duke should reign over them."[179] The claim of Henry, as opposed to that of the earl of March, was indeed ridiculous; but it is by no means evident that, in such cases of extreme urgency as leave no security for the common weal but the deposition of a reigning prince, there rests any positive obligation upon the estates of the realm to fill his place with the nearest heir. A revolution of this kind seems rather to defeat and confound all prior titles; though in the new settlement it will commonly be prudent, as well as equitable, to treat them with some regard. Were this otherwise it would be hard to say why William III. reigned to the exclusion of Anne, or even of the Pretender, who had surely committed no offence at that time; or why (if such indeed be the true construction of the Act of Settlement) the more distant branches of the royal stock, descendants of Henry VII. and earlier kings, have been cut off from their hope of succession by the restriction to the heirs of the princess Sophia.
