Foundations of Tort
“A broad two-stage approach or any other approach is only a framework, a more or less methodical way of tackling a problem. How it is formulated should not matter in the end. Ultimately the exercise can only be a balancing one and the important object is that all relevant factors be weighed. There is no escape from the truth that, whatever formula be used, the outcome in a grey area case has to be determined by judicial judgment. Formulae can help to organise thinking but they cannot provide answers.”
