[25 marks]Critically evaluate the doctrine of promissory estoppel as developed in Central London Property Trust Ltd v High Trees House Ltd (1947). To what extent does promissory estoppel operate as a "shield and not a sword" in English law? Consider whether the doctrine adequately protects parties who rely on promises that lack consideration, and discuss whether English law should follow the Australian approach in Waltons Stores (Interstate) Ltd v Maher (1988) by allowing promissory estoppel to found a cause of action. Reference should be made to the requirements established in Combe v Combe (1951) and the suspensory nature of the doctrine as explained in Tool Metal Manufacturing Co v Tungsten Electric Co (1955).
