The main contractor on the site subcontracted the interior plastering. Fifteen years later, the plasterwork collapsed causing injury. The plasterer had not used the plaster specified.
Held: Appeal allowed. A contractor may have contractual or statutory duty to supervise, but not necessarily in tort. A main contractor will not have responsibility in tort for failure to supervise the acts of a sub-contractor where it would be unreasonable to expect him to provide supervision.
