William Strong, Mining Company v. Taylor — Opinion of the Court
“ Apart from the fact that the defendant claims under Payne and Cook, and is therefore not at liberty to dispute their title, it is impossible to discover how it could have been injured by the reception of Exhibits A and C. The instrument C was certainly sufficient to transfer an interest in the mining claim, and the mining rules, at worst, were only immaterial. The admission of immaterial or irrelevant evidence is no sufficient reason for reversing a judgment, when it is apparent, as in this case, that it cannot have affected the verdict or the finding injuriously to the plaintiff in error. ”
