2. Evidence of facts which do not belong to the matter in question, is impertinent and inadmissible. In general, what is immaterial is impertinent, and what is material is, in general, not impertinent. 1 McC. & Y. 337. See Gresl. Ev. Ch. 3, s. 1, p. 229. Impertinent matter, in a declaration or other pleading is that which does not belong to the subject; in such case it is considered as mere surplusage, (q. v.) and is rejected. Ham. N. P. 25. Vide 2 Ves. 24; 5 Madd. R. 450; Newl. Pr. 38; 2 Ves. 631; 5 Ves. 656; 18 Eng. Com. Law R. 201; Eden on Inj. 71.
4. In equity a bill cannot, according to the general practice, be referred for impertinence after the defendant has answered or submitted to answer, but it may be referred for scandal at any time, and even upon the application of a stranger to the suit. Coop. Eq. Pl. 19; 2 Ves. 631; 6 Ves. 514; Story, Eq. Pl. 270. Vide Gresl. Eq. Ev. p. 2, c. 3, s, 1; 1 John. Ch. R. 103; 1 Paige's R. 555; I Edw.
