energy, zeal, and earnestness proportioned to the magnitude and importance of the interest of the Commons of Great Britain in the religious observation of the rule, _that the Law of Parliament, and the Law of Parliament only, should prevail in the trial of their impeachments_.
In the year 1715 (1 Geo. I.) the Commons thought proper to impeach of high treason the lords who had entered into the rebellion of that period. This was about six years after the decision in the case of Sacheverell. On the trial of one of these lords, (the Lord Wintoun,[13]) after verdict, the prisoner moved in arrest of judgment, and excepted against the impeachment for error, on account of the treason therein laid "not being described with sufficient certainty,--the day on which the treason was committed not having been alleged." His counsel was heard to this point. They contended, "that the forfeitures in cases of treason are very great, and therefore they humbly conceived that the accusation ought to contain all the certainty it is capable of, that the prisoner may not by general allegations be rendered incapable to defend himself in a case which may prove fatal to him: that they would not trouble their Lordships with citing authorities; for they believed there is not one gentleman of the long robe but will agree that an indictment for any capital offence to be erroneous, if the offence be not alleged to be committed on a certain day: that this impeachment set forth only that in or about the months of September, October, or November, 1715, the offence charged in the impeachment had been committed." The counsel argued, "that a proceeding by impeachment is a proceeding at the Common Law, for Lex Parliamentaria is a part of Common Law, and they submitted whether there is not the same certainty required in one method of proceeding at Common Law as in another."
The matter was argued elaborately and learnedly, not only on the general principles of the proceedings below, but on the inconvenience and possible hardships attending this uncertainty. They quoted Sacheverell's case, in whose impeachment "the precise days were laid when the Doctor preached each of these two sermons; and that by a like reason a certain day ought to be laid in the impeachment when this treason was committed; and that the authority of Dr. Sacheverell's case seemed so much stronger than the case in question as the crime of treason is higher than that of a misdemeanor."
Here the Managers for the Commons brought the point a second time to an issue, and that on the highest of capital cases: an issue, the event of which was to determine forever whether their impeachments were to be regulated by the law as understood and observed in the inferior courts. Upon the usage below there was no doubt; the indictment would unquestionably have been quashed. But the Managers for the Commons stood forth upon this occasion with a determined resolution, and no less than four of them seriatim rejected the doctrine contended for by Lord Wintoun's counsel. They were all eminent members of Parliament, and three of them great and eminent lawyers, namely, the then Attorney-General, Sir William Thomson, and Mr. Cowper.
Mr. Walpole said,--"Those learned gentlemen [Lord Wintoun's counsel] seem to forget in what court they are. They have taken up so much of your Lordships' time in quoting of authorities, and using arguments to show your Lordships what would quash an indictment in _the courts below, that they seemed to forget they are now in a Court of Parliament, and on an impeachment of the Commons of Great Britain_. For, should the Commons admit all that they have offered, it will not follow that the impeachment of the Commons is insufficient; and I must observe to your Lordships, that neither of the learned gentlemen have offered to produce one instance relative to an impeachment. I mean to show that the sufficiency of an impeachment was never called in question for the generality of the charge, or that any instance of that nature was offered at before. The Commons don't conceive, that, if this exception would quash an indictment, it would therefore make the impeachment insufficient. I hope it never will be allowed here as a reason, that what quashes an indictment in the courts below will make insufficient an impeachment brought by the Commons of Great Britain."
The Attorney-General supported Mr. Walpole in affirmance of this principle. He said,--"I would follow the steps of the learned gentleman who spoke before me, and I think he has given a good answer to these objections. I would take notice that we are upon an impeachment, not upon an indictment. The courts below have set forms to themselves, which have prevailed for a long course of time, and thereby are
