“I start by considering what is the correct approach on a summary application of the nature of Mr. Richards's application at this early stage in the action when the pleadings show significant disputes of fact between the parties going to the existence and scope of the alleged duty of care. The correct approach is not in doubt: the court must be certain that the claim is bound to fail. Unless it is certain, the case is inappropriate for striking out (see Barrett v Enfield London Borough Council[2001] 2 AC 550 at p. 557 per Lord Browne-Wilkinson). Lord Browne-Wilkinson went on to add: “[I]n an area of the law which was uncertain and developing (such as the circumstances in which a person can be held liable in negligence for the exercise of a statutory duty or power) it is not normally appropriate to strike out. In my judgment it is of great importance that such development should be on the basis of actual facts found at trial not on hypothetical facts assumed (possibly wrongly) to be true for the purpose of the strike out.” “[I]n an area of the law which was uncertain and developing (such as the circumstances in which a person can be held liable in negligence for the exercise of a statutory duty or power) it is not normally appropriate to strike out.
