246 F. 936 | 8th Cir. | 1917
It is a familiar rule that collateral or irrelevant facts that fix the time at which a relevant fact occurred are admissible in evidence so far as necessary for the purpose, but it cannot be employed as a pretext for the admission of evidence that is in itself incompetent and prejudicial. In the case at bar the time when the witness made the measurements could have been elicited by simple and direct qüestions so confined in their scope. Proof of or reference to the making of changes was wholly unnecessary, yet by repeated questions the fact was emphasized and made prominent. Not only was it unnecessary, hut the evidence so brought in was distinctly prejudicial and incompetent upon the issue being tried. It is the settled doctrine of the courts of the United States that in actions for injuries alleged to have been caused by defective machinery, appliances, or places of work evidence of subsequent alterations or repairs has no legitimate tendency to prove negligence at the time of the accident and is calculated to prejudice the defendant.
