after stating the case delivered his opinion as follows:
It is contended, that there can be no perjury where a man believes what he swears. But it appears to me that a position so extensive cannot be supported. He ought at least to have some probable cause for belief, unless the oath be taken under such circumstances of haste or surprise as afford no opportunity of deliberation. If a man undertakes to swear to a matter of which he has no knowledge, he is perjured, although what he has sworn turns out to be true. This is *251proved by the case cited by the defendant’s counsel from 3 Inst, 166, where a man was adjudged guilty of perjury for swearing to the value of goods which he never saw or knew, although his valuation was not incorrect. There is corruption in undertaking to swear positively to a thing of which you have little knowledge, 'and which you may know if you will take the trouble to enquire; and when there is this kind of corruption, the law implies malice. Cornish must have known that it was difficult to distinguish a man’s person in a crowd in the night, and he ought to have made some enquiry before he took the oath. If he had acted with reasonable caution, he would have discovered the truth. It is objected that it may be of dangerous consequence, if witnesses are convicted for swearing to what they believe to be true. On the other hand, it will be more dangerous if they are tox escape punishment, who rashly and obstinately persist in a false oath, in a matter of which they will not take the pains to inform themselves. It is said by Blackstone, 4 Black. 137, that there is perjury where one swears xvilfully, absolutely and falsely. That the oath of Cornish was absolute sad false is not denied; It was wilful also, according to the legal import of that word, by which it is only understood that the oath is taken with some degree of deliberation, and “ not merely through surprise or inadvertency, u or a mistake of the true state of the question;” (3 Bac. 814, A.) Now here was great deliberation, or at least room for deliberation, for there was an interval of two days between the first and second oath, and the first was taken two days after the affray in which the defendant was shot. In cases where the oath is clearly false, I know no rule more reasonable, than to leave it to the jury to decide, whether there was any probable ground forrnistake. I am therefore of opinion that a new trial should not be granted.
Brackenridge J.The question resolves itself into this, can one be guilty of peijury who believes what he says to be the truth? Probable cause, or reaso?iable ground of belief, in a prosecution in a course of justice, will exempt from damages. The want of probable cause or reasonable ground, pari ratione will subject to the conviction of perjury; for 'the mala mens, malilla, or malice, is ah inference of law from *252the want of probable cause or reasonable ground. I am not to he at the mercy of the -weakness of a man, and the law will protect against the weakness, as well as against the actual wickedness of him, who attacks my reputation by an oath in a court of justice. It is the same thing to me, whether it was his weakness or actual malice and wickedness, that led him to take the oath. It interests the public, that rash and unadvised swearing a crime upon another, should be restrained; and how can this be done, if the only enquiry shall be, whether the weak man really thought that which he swore was true.
In the present case, it cannot be doubted, but-that an action of slander could have been supported on words spoken to the effect of what was sworn, even though believed by him publishing. The being spoken in a course of justice will protect against this. The being sworn in a course of justice, will not protect on the ground of a probable cause. There was no probable cause in this case, no reasonable ground. The charge was rashly made, and wantonly persisted in, without throwing himself open to conviction of his mistake, or using due means to inform himself of it, though he would seem to have had abundant opportunity of making enquiry, and informing himself as to the ground of his misconception. The not having done this, shews a carelessness as to what he swore; and even when in court he persisted in his first belief.
We are between Scylla and Charybdis in this case. On the one hand, there is the risk of discouraging testimony given for the Commonwealth; on the other hand, there is the risk of individuals from rash and unadvised swearing. There can be no doubt but' that an action for a malicious prosecution would lie in this case; but what satisfaction would it be to recover damages against a defendant of no property? It ought to be at a man’s risk to undertake to swear positively, under circumstances where he ought to have mistrusted his vision, and could not have been certain,.. as to what he undertook to say positively that he saw. This was the case here.
New trial refused.
