In the above entitled cause the grand jury in and for the county of Iowa, at the April term of the district court for said county for 1839, found a bill of indictment against Hunter for adultery. He appeared and filed a general demurrer, which was by the court overruled and the defendant adjudged guilty as charged in the indictment; whereupon, for the purpose of transmitting this cause to this court for a decision upon alleged error therein, it was agreed that final judgment should not then be pronounced.
The court here is given to understand by the parties that the ground of objection argued on demurrer was that the indictment did not charge the defendant to have been a married man, while the contrary is admitted, but did charge that he committed adultery with one Elizabeth Mills, lawful wife of Alonzo D. Mills.
The only point for the consideration of the court is, “could the defendant, Hugh R. Hunter, who is acknowleged to be a single man, commit the offense of adultery ?” The indictment in this case was found under the 9th section of the act for the punishment of crimes (Michigan Laws, 446), by which section the punishment for adultery is prescribed, but the offense not defined, making it necessary to resort to other sources for that information.
Jacobs, in his Law Dictionary, in defining adultery says : “Adultery, adulteriam quasi adulterius .thoram. In 1 Hen. VII and in divers old authors termed admwtry, the sin of incontinence between two married persons, or if but one of the persons be married, it is nevertheless adultery; but in this case it is called single adultery to distinguish it from the other, which is double.”
Here it becomes necessary, in order to fix the meaning of the latter part of his definition, to determine what he meant by single adultery. He places it in contradistinction to double, in which both are married, and it would seem in every just interpretation of the language to mean that the married party to single adultery must be the one guilty of that offense.
*93By reference to Respublica v. Roberts, 1 Yeates’ (Pa.) 6, and 2 Dall. 124, it will be seen that in the courts in Pennsylvania a case precisely in point was decided, the statute of that State, like the one under which this indictment was found, prescribing the punishment, but not defining the offense, of adultery. This is the first available report of an American decision we have been able to obtain, and is, from its long standing and correctness of decision, considered conclusive. *
The language as reported in Dallas is in relation to the adultery: “The court, after consideration, delivered an unanimous opinion that, under the act of assembly and the uniform practice of eighty-five years (a practice which, though it does not make the law, must be strong evidence of what the law is), the indictment for adultery could not be supported.” The court is unanimously of opinion that the court below erred in overruling the demurrer, and that its decision thereon be reversed.
