Massachusetts House of Representatives, Circular Letter to the Colonial Legislatures11 Feb. 1768S. Adams Writings 1:185
The House have humbly represented to the ministry, their own Sentiments that His Majestys high Court of Parliament is the supreme legislative Power over the whole Empire: That in all free States the Constitution is fixed; & as the supreme Legislative derives its Power & Authority from the Constitution, it cannot overleap the Bounds of it without destroying its own foundation: That the Constitution ascertains & limits both Sovereignty & allegiance, & therefore, his Majestys American Subjects who acknowlege themselves bound by the Ties of Allegiance, have an equitable Claim to the full enjoymt of the fundamental Rules of the British Constitution. That it is an essential unalterable Right in nature, ingrafted into the British Constitution, as a fundamental Law & ever held sacred & irrevocable by the Subjects within the Realm, that what a man has honestly acquird is absolutely his own, which he may freely give, but cannot be taken from him without his consent: That the American Subjects may therefore exclusive of any Consideration of Charter Rights, with a decent firmness adapted to the Character of free men & Subjects assert this natural and constitutional Right.
