Roberts v. Ring

Supreme Court of Minnesota
1919 Minn. LEXIS 463, 143 Minn. 151, 173 N.W. 437 (1919)
ELI5:

Rule of Law:

A minor's contributory negligence is measured against the care expected of a child of similar age and maturity, whereas an adult's negligence is measured by the objective standard of a reasonably prudent person, which is not lowered by the adult's physical infirmities or age.


Facts:

  • Ring, a 77-year-old man with defective sight and hearing, was driving his automobile on a busy street.
  • John B. Roberts, a 7-year-old boy, ran into the street from behind a horse-drawn buggy.
  • Roberts ran directly in front of Ring's oncoming automobile.
  • Ring's car, traveling at approximately four to five miles per hour, struck Roberts and passed completely over him, causing injury.

Procedural Posture:

  • The father of John B. Roberts sued Ring on his son's behalf in a trial court to recover damages for personal injury.
  • The case was tried before a jury, which returned a verdict in favor of the defendant, Ring.
  • The plaintiff, Roberts, appealed the judgment entered on the jury's verdict, assigning error to the trial court's jury instructions.

Issue:

In a negligence action, is a minor plaintiff held to the adult standard of care for contributory negligence, and may a defendant's physical infirmities lower the standard of care they owe to others?


Opinions:

Majority - Hallam, J.

No. A child's conduct is measured against the standard of care expected of a child of similar age and maturity, not the adult standard of an ordinarily prudent person. Conversely, an adult defendant's physical infirmities do not lower the objective standard of care required, which is that of an ordinarily prudent normal person. The court found that the trial court's jury instructions were erroneous on both points. For the child, the instruction improperly applied the adult standard. For the defendant, the instruction improperly suggested that his age and infirmities could excuse his conduct, when in fact such infirmities presented a reason for him to exercise greater caution or to refrain from driving altogether on a crowded street.



Analysis:

This case solidifies the dual standard in negligence law by clearly distinguishing the standard of care for minor plaintiffs from that of adult defendants. It affirms the subjective standard for a child's contributory negligence, taking into account their age and maturity, which can excuse conduct that would be negligent in an adult. Simultaneously, it reinforces the strict, objective 'reasonably prudent person' standard for adult defendants, establishing that personal physical infirmities cannot serve as a defense to lower this standard. This prevents defendants from using their own limitations as a shield against liability and upholds a uniform, predictable standard of care required for public safety.
