The provision in Gen. Sts. c. 131, § 14, that parties to a cause may be witnesses, is qualified by the exception that “ where one of the original parties to the contract or cause of action in issue and on trial is dead, or is shown to the court to be insane, the other party shall not be admitted to testify in his own favor; and where an executor or administrator is a party, the other party shall not be admitted to testify in his own favor, unless the contract in issue was originally made with a person who is living and competent to testify, except as to such acts and contracts as have been done or made since the probate of the will, or the appointment of the administrator.” The St. of 1865, c. 207, § 1, contains the farther provision that “ whenever the contract or cause of action in issue and on trial was made or transacted with an agent, the death or insanity of his principal shall not prevent any party to the suit or proceeding from being a witness in the case: provided, such agent shall be living and competent to testify.”
The object and purpose of these exceptions obviously are, to put the two parties to a suit upon terms of substantial equality, •n regard to the opportunity of giving testimony. In general, when parties have contracted with each other, each may be *228supposed to have an equal knowledge of the transaction; and both, if living and of sound mind, are allowed to testify. But if one is precluded from testifying by death or insanity, the other is not entitled to the undue advantage of being a witness in his own case. Where, however, a party has contracted through an agent, if the agent is living, the death of the principal does not deprive his personal representative of the testimony of the one most fully acquainted with the facts of the case ; and the other party may without injustice be admitted as a witness. Indeed, if he were not, the injustice might be the other way.
The St. of 1865 must therefore be construed as if, instead of saying “ shall not prevent any party to the suit or proceeding,” it had said, “ shall not prevent any party to the suit or proceeding who made the contract with the agent.” It could not, we think, have been intended to have any application to the case of a suit by an agent against the representatives of his principal.
In the case at bar, an agent sues the administratrix of his principal upon the implied contract of indemnity for acts done in the principal’s service. One party to the contract is dead, and the other cannot be a witness. The exception in St. 1865 is not applicable.
The testimony of the plaintiff being excluded, there was nothing to support that part of his case upon which he offered to testify. We should by no' means intend to intimate that, if
the testimony were competent, it would establish any claim against the defendant. But the decision of the question of evi deuce renders the discussion of other questions unnecessary.
Exceptions overruled.
