And this prerogative," he adds, "our progenitors have in all times used and enjoyed."[****] The intervals between sessions, we may observe, were frequently so long as to render it necessary for a prince to interpose by his prerogative.

The legality of this exertion was established by uniform and undisputed practice; and was even acknowledged by lawyers, who made, however, this difference between laws and proclamations, that the authority of the former was perpetual, that of the latter expired with the sovereign who emitted them.[v] But what the authority could be which bound the subject, yet was different from the authority of laws, and inferior to it, seems inexplicable by any maxims of reason or politics: and in this instance, as in many others, it is easy to see how inaccurate the English constitution was, before the parliament was enabled, by continued acquisitions or encroachments, to establish it on fixed principles of liberty.
