## Facts

- Watson sued Rheinderknecht for damages for alleged assault and battery arising from a dispute following a sheep sale.
- Rheinderknecht agreed to sell sheep to Watson; Watson paid $10 as a binder.
- On the agreed day, Rheinderknecht brought the sheep to a railroad yard for shipment and delivered them to Watson.
- At a bank, Watson objected that the lot included too many bucks and tendered the price minus $40, intending to withhold $40 until sale returns; Rheinderknecht refused, and they separated.
- Watson returned to the yard, prepared the railcar, loaded the sheep, closed and stapled the door, and began to leave.
- Rheinderknecht and his brother returned, demanded the sheep back, and Watson refused to surrender possession.
- A physical altercation occurred; Watson (about 60 years old and in poor health from prior war-related injuries) claimed the assault worsened his preexisting condition.
- At trial, the court excluded evidence offered by Watson regarding his prior condition and the extent to which the assault aggravated it.
- The jury returned a defense verdict; the trial court denied Watson’s motion for a new trial.

## Issues

1. Whether an intentional tortfeasor is liable for the direct and immediate consequences of an assault and battery even if the specific extent of harm, including aggravation of prior injuries, was not foreseen.
2. Whether evidence of a plaintiff’s preexisting condition and aggravation of that condition by the assault is admissible on damages in an assault and battery action.
3. Whether, even on the defendant’s version of events, the defendant lacked justification and acted as the aggressor, making a defense verdict unsupported.

## Decision

- The Minnesota Supreme Court reversed the order denying a new trial and directed that a new trial be granted.
- The court held the trial court erred by excluding evidence of Watson’s preexisting injuries and the extent of their aggravation.
- The court stated that the perpetrator of a tort is responsible for the direct and immediate consequences of the wrongful act, regardless of whether those consequences were contemplated or foreseeable.
- On the defendant’s own account, the court concluded Rheinderknecht was the aggressor from the beginning and not justified; a properly instructed jury should have found for Watson in a substantial amount.

## Legal Principles

- A tortfeasor is liable for the direct and immediate consequences of a wrongful act even if the particular injuries or their extent were not anticipated or foreseeable.
- In an assault and battery action, damages may include worsening of a plaintiff’s preexisting condition caused by the assault.
- Evidence of the plaintiff’s prior physical condition and the extent of aggravation is relevant and admissible to permit a full damages determination.
- After delivery of property, a seller generally may not use force to retake possession; forceful self-help may constitute an unjustified assault, supporting civil liability.

## Conclusion

The court ordered a new trial because the jury was improperly prevented from hearing damages evidence on aggravation of Watson’s preexisting injuries and because the defendant’s own account showed unjustified aggression; an intentional tortfeasor must answer for all direct consequences to the plaintiff, including increased harm due to prior fragility.
