Edmund Burke, Letter to the Sheriffs of Bristol1777Works 1:28
The king's negative to bills is one of the most indisputed of the royal prerogatives; and it extends to all cases whatsoever. I am far from certain, that if several laws which I know had fallen under the stroke of that sceptre, that the public would have had a very heavy loss. But it is not the propriety of the exercise which is in question. The exercise itself is wisely forborne. Its repose may be the preservation of its existence; and its existence may be the means of saving the constitution itself, on an occasion worthy of bringing it forth.
