[27] Whether an application for security for costs was, or ought to have been, made against a company conducting litigation will be one of the factors to take into account. Similarly, whether the non-party against whom an order is sought ought to have been warned prior to trial will depend on all the circumstances. In this case, that no security for costs application was brought by Westpac against Babsari is not a compelling factor for refusing to order the relief sought. There is every chance that Westpac would have been unsuccessful because Babsari sought nothing save the securities from the bank in the exercise of its right to subrogation. It was not until the evidence unfolded and his Honour made the findings that he did that Babsari's role through Mr Tsui became clearer. As to the second matter, a director in Mr Tsui's position, seized of all the facts did not, in the interests of justice, need the warning referred to in Metalloy.
