This is a writ of error to the court of common pleas of Philadelphia county. It is an action brought by William Wilson, the defendant in error, who was plaintiff below, against William Miller, for money had and received for his use. Wilson was in the navy of the United States, and entitled to a share of prize money. Miller was the agent for prizes; and the dispute was, whether the plaintiff was entitled to a share in the capacity of a sailmaker, or of a common seaman. He claimed as a sailmaker. In the course of the trial, exceptions were taken to the opinion of the court on two points with respect to the admission of evidence, which are stated in a bill of exceptions annexed to the record. The defendant offered to give in evidence the deposition of John Shaw, who was captain of the United States schooner Enterprise, when she captured the prize, concerning which the dispute arose. This deposition was rejected by the court, because Shaw, as commander of the said schooner, was interested in the decision of the cause. There was no proof of any interest except such as arose from his being commander. I am therefore of opinion that he was a competent witness; because by the act of congress, regulating the distribution of prizes, he was entitled to a certain proportion, which could not be affected by the share which the plaintiff would draw, either as a sailmaker or common seaman. It has indeed been suggested, in the course of the argument here, that he had an interest in preventing the plaintiff’s recovery, because he had given a certificate that the plaintiff was sailmaker on board the Enterprise, and therefore if the plaintiff recovered, Shaw might be subject to an action by the rest of the crew for having certified what was not true; but it is unnecessary to enter into the merits of this objection, because, not ap*534pearing on the record, we can take no noticeofit.lt is not stated on the record, that Shaw gave any certificate.

I shall give no opinion on the exception to the certificate of Thomas Turner; because I take for granted, that the plaintiff, when this cause shall be tried again, will take care to be furnished with a certificate from the navy department, free from all the objections which have been made to this.

On the whole I am of opinion that the judgment of the court of common pleas be reversed, and a new trial ordered.

I shall avoid giving a decisive opinion whether the certificate issued by the accountant of the navy department, under the seal of that office, was evidence in this case. But I have no doubt that a true copy of the muster rolls, properly certified, would have been admissible. The ground, on which I think the judgment should be reversed, is, that the deposition of captain John Shaw was not permitted to go to the jury. It was objected that he was interested in the event of the cause, as commander of the schooner Enterprise, on board whereof was the defendant in error, who has instituted this suit for the recovery of his share of prize money as a sailmaker.

It has been candidly admitted by the counsel of Wilson, that captain Shaw's prize money could neither be diminished nor increased by whatever might be the result of this action. The share of the captain is regulated by an act of congress passed 23d April 1800. But it is said that if captain Shaw should be permitted to substantiate the fact, that the plaintiff below was not a sailmaker on board, he would thereby render himself responsible; and consequently is interested. The force of this reasoning rests on the fact of his being the officer who made the returns from which the certificate is extracted. But this does not appear from the certificate, which only states, that it appears by the rolls of the schooner Enterprise, filed in the accountant’s office, that William Wilson was sailmaker on board from the 6th July 1800, to 5th March 1801. Now Shaw might not have made these returns; and in fact it appears by the deposition that he had the command of the vessel from October 1799 to October 1800, when the state of his health obliged him to leave her. The result therefore would be, that of the eight months, during which Wilson was on board of the schooner, Shazv commanded her only three months.

*535But even admitting that captain Shaw had made the returns, I do not see how this would affect his competency. His was offered by the defendant below, in order to shew that he was not a sailmaker, within the true meaning of the act of congress, entitled in that quality to prize money. He is to swear against his own interest; because if the making of a false or imperfect return would create a liability, he is brought to establish a fact which may eventually produce that effect. A man will be admitted to swear against his own inte* rest, though not in favour of it.

In every point of view, I think captain Shaw was a witness; that his testimony ought to have been received; and consequently that the judgment below should be reversed, and a venire facias de novo be awarded.

Judgment reversed, and venire de novo awarded.
