¶1The opinion of the court was delivered by
¶2The defendant was not a competent witness, “unless the contract in issue was originally made with a person who is (was) living and competent to testify.” The defendant claimed that the contract for the apples was made with Harvey Cairns, acting as agent for the testate, and who was present at the trial and testified. Conceding that the testimony of the defendant’s witness tended to establish the fact of agency, the question was one for the court. The defendant insists that he should have been permitted to testify, and the question of agency submitted to the jury, and if they found it established, they should then consider the testimony of the defendant upon the various points upon which he gave testimony, and if they did not find the fact of agency proved, reject the testimony. ’ It was a question of competency or incompetency of the defendant as a witness, and that question is always for the court, and should never be submitted to the jury. 1 Greenl. Ev. (14th Ed.) s. 19 and note a; 1 Tay. Ev. s. 21; Bartlett v. Smith, 11 M. &. W. 483; Reg v. Hill, 5 Eng. L. & Eq. 517; Cook v. Mix, 11 Conn. 432; Holcomb v. Holcomb, 28 Conn. 177; Harris v. Wilson, 7 Wend. 57; Reynolds v. Lounsbury, 6 Hill, 534; Dole v. Winslow, 12 Met. 157; McManagil v. Ross, 20 Pick. 99. In some jurisdictions it has been held that, in doubtful cases, it is notimproper to refer the existence of the facts upon which the competency depends to the jury; and, in some instances., it is intimated that it should be done. Hartford F. Ins. Co. v. Reynolds, 36 Mich. 502; Johnson v. Kendall, 20 N. H. 301; Bartlett v. Hoyt, 33 N. H. 151; Dart v. Heilner, 3 Rawle, 107; Gordon v. Bowens, 16 Penn. St. 226; Haynes v. Hemsicker, 26 Penn. St. 58.
¶3*174Questions of fact affecting the admissibility of testimony often arise, and it would be very inconvenient, if not impracticable, to submit them to the decision of a j ury. The testimony as to the competency of a witness, and that of the witness as to the issues upon trial, would all go to the jury with directions that if they found the witness incompetent, it would be their duty to disregard his evidence upon the main issues, which in many instances it might be impossible to do. Having heard the illegal testimony discussed by counsel, the confusion which would probably arise in separating the legal from the illegitimate testimony would no doubt lead to the rendition of erroneous verdicts, with no relief for the unfortunate party; and certainly this should not be the rule in a jurisdiction where the admission of illegal evidence is not cured by a direction from the court to disregard it. State v. Hopkins, 50 Vt. 316; State v. Meader, 54 Vt. 126; Hall v. Jones, 55 Vt. 297; Rob. Dig. 700, pl. 55.
¶4In Cook v. Mix, supra, the question was whether the witness had an interest in the event of the suit and the court said it “ was a question of fact to be determined on the evidence before the court. It is claimed in the first place, that the judge mistook the law in not submitting this question to the jury, and this claim has been gravely urged before this court, It is sufficient to observe that the claim is as unfounded as it is novel, that it has no support either in principle or authority, and is utterly incapable of being reduced to practice.”
¶5It is not by any means true that all questions of fact in a jury trial must be left to the jury; numerous instances where the court passes upon such questions can be readily called to mind, e. g., whether a witness is an expert; or a dying declarant entertained hopes of recovery ; or a writing to be used as a test in comparison of handwriting is proved ; or a witness has sufficient mental capacity to testify, or is the husband or wife of the party; or declarations are so far a part of the res gestae as to be admissible ; or a confession was induced by threats; or a document has been duly or sufficiently stamped ; or sufficient search been made for a lost document to warrant the introduction of secondary *175evidence. Many other instances might be given. In the beginning of a jury trial, suppose a woman is offered as a witness for the plaintiff and the defendant objects for that she is the wife of the plaintiff. The question is purely one of fact. "Will anyone claim that her testimony should be given upon the main issues, and the question of whether wife or not’be left to the jury, and then if they find her to be the wife, discard her testimony, but if not, consider it ? Conceive that in a suit in favor of several plaintiffs the question should arise in respect to each one. Well might the Connecticut court characterize the claim of the defendant as unfounded as it was novel. The court below not being satisfied from the evidence that the contract in issue was made with the agent of the testate, properly held the defendant incompetent.
¶6Judgment affirmed.
