The trial of this case seems to have proceeded upon the ground that the female upon whom the defendant was charged to have committed the offence, was incompetent to be sworn as a witness, by reason of defect of in*22tellect. After the evidence of Smith, .the principal witness, had been given, tending to show a violent assault by defendant upon the female with intent to commit the offence, evidence was received, under objection and exception to its admissibility, of certain signs and motions made by her to the witness immediately after the offence is supposed to have been perpetrated, indicating to the witness, who it seems could understand the purport and meaning of them, that the offence charged had been committed by some person. Was such evidence upon any ground admissible 1 It is not denied but that, if the female had been a competent witness, had been sworn and had given her evidence, it would have been competent to prove by other witnesses her acts and declarations immediately after the offence was charged to have been committed; not as confirmatory of the truth or falsity of her evidence, but as affecting the credibility of her testimony, (4 Bl. Comm. 213 ; 1 Phill. Ev. 233, ed. 1839.) So the state and appearance of the female, marks of violence upon her person, and the torn and disordered state of her dress recently after the transaction, as in the present case to some extent, are material circumstances, and always admissible in evidence, whether she be sworn or not. (1 Hale, 628, 9 ; 1 Hawk. 41, § 6; 4 Bl. Comm. 213 ; East’s P. C. 446.)
It is insisted on the part of the people, that when persons are excluded from being witnesses for want of understanding, whether it arises from immaturity or defect of intellect, evidence may be given of their declarations as to the offence charged.
It is said, (1 Chit. Cr. Law, Riley’s ed. 481, 1 Leach, 110, 199,) “ It was once thought that when the party immediately injured was an infant of tender years, the parents of the child might be admitted to state the account he had given of the transaction immediately after it had taken place, and that the infant might be examined though not sworn ; (and so is the authority of 2 Hale, 278, 9, Bull. N. P. 293 ;) but both these ideas are now rejected, and it is fully established that if the infant is of competent discretion, he may he sworn, however young; and if not, no evidence whatever can be given respecting his assertions.”
That being the true rule in case of a person immature in in*23tellect, I cannot see why the reason of the rule does not apply with as much force to exclude all evidence of the declarations, assertions or signs made, supposed to communicate ideas, by a person who is incompetent to be sworn as a witness by reason of idiocy, or weakness of intellect for any cause, as evidence of the commission of the offence, or to affect the credit of any other-witness. I do not understand the objection as going against any evidence of the appearance and condition of the female at the time, hut only as against communications made by her to the witness, by which she informed him of particular injuries inflicted upon her, tending to prove forcible sexual connexion, or from which it could properly be inferred.
The evidence of Trisket proceeded upon the idea that the female was of sense, sufficient to have intelligence conveyed to her, and to communicate intelligence to the witness, by signs and motions. . Trisket testified that she was not a fool. She could not talk, hut could make signs and had understanding enough to take care of herself, to communicate her wants, and to render much service at the poor bouse, of which she was an inmate. "She observed things that occurred about her, frequently informed witness of them by signs, and that he was able to comprehend her signs, and had no difficulty in carrying on ordinary conversation with her, &c. I see no reason, from the account given of her by this witness, why she was not competent as a witness to give evidence, through the medium of this witness as an interpreter, by signs. What more reason would it require to give evidence under oath, than to give facts without being sworn ? The only question in the admission of her as a witness was, had she sufficient reason ? If she had sufficient reason to have intelligence conveyed to her by the witness, and to communicate facts to the understanding of the witness, although she was not able to talk or write, she could have been sworn and testified through him by signs.
In John Ruston's case, (1 Leach, 455,) “ A man deaf and dumb from his birth was offered as a witness on the part of the public on an information for grand larceny. Martha Ruston, his sister, being examined on the voir dire, it appeared that she and *24her brother, for a series of years, had been able to understand each other by means of certain arbitrary signs and motions, which necessity-had invented between them. She acknowledged that these signs were not significant of letters, syllables, words or sentences, but were expressive of general propositions and entire conceptions of mind; and that the subject of their conversation had been generally confined to the domestic concerns and familiar occurrences of life. She believed, however, that her brother had a perfect knowledge of the tenets of Christianity, and was certain that she could communicate to him true notions of the moral and religious nature of an oath, and of the temporal dangers of perjury. The witness was objected to but admitted by the court, and sworn in the usual form. Martha Huston was sworn well and truly to interpret to John Huston-the questions and demands made by the court to him, and his answers made to them.”
It should, however, be understood, that I do not place my opinion as to the admissibility of the evidence objected to, upon the question whether the female witness was competent to testify, or not. In either case, I consider the evidence inadmissible upon principle. The view I have taken of it, I think is sustained by recent cases in the English courts; (Reg. v. Gutridge, 9 Carr. & Payne, 471; Reg. v. Megson, id. 428;) and I do not doubt that the true rule is, that when the person upon whom the offence is charged to have been committed is incompetent, by reason of infancy, idiocy, insanity and the like, to be sworn and give evidence as a witness, that no evidence of the assertions or declarations of such person, descriptive of the offence or the offender, can be received in evidénce; and that the declarations of the person upon whom the injury has been inflicted in relation to it are only proper to be given in evidence to affect the credibility of the person, after having testified in the cause. I think the objection was well taken.
The judgment of the court of oyer and terminer must be reversed.
