Defendant was carrying out research on the foot and mouth virus which they leaked into surrounding farms so that cattle in the area caught the virus and couldn’t be sold at auction by Plaintiff, who would have been able to claim commission on each animal sold.
Held that there was a duty to take reasonable care owed only to those persons whose person or property might foreseeably be injured by a failure to take such care, but not to Plaintiff who had no proprietary interest in the property damaged.
The only proprietary interest of Plaintiff was in the market itself which would obviously not be damaged by the outbreak of the virus.
