47 What are the limits to be placed on this right to indemnification? This is a matter which has rarely engaged the attention of either the Australian or the English Courts. Presumably if the activity which generated the liability in question were a breach of trust, the right to an indemnity under the general law would no longer exist; similarly if it were criminal in nature, but no criminal offences were charged against NKH, its associates or officers. Again, one must in principle incline to the view that if the activity in question had been fraudulent the law would withhold the right to indemnification; but in the present case Tamberlin J expressly negatived fraud. I find it difficult to formulate any other limitations. United States authorities, to which Hamilton J refers, might be read as establishing either or both these propositions: (a) that the activity in respect of which indemnity is claimed must be "reasonable", and (b) that the activity must be "proper". In my view, neither such limitation exists in Australian law. As to the former, it is in the circumstances, meaningless; no conduct has to be castigated as "unreasonable" unless one has a clear criterion of what constitutes reasonableness, and here there is none. As to the latter, it is almost as meaningless to endeavour to apply some hypothetical standard of propriety in ordinary commercial life, absent fraud and crime. I find it difficult to view occasional breaches of Trade Practices legislation as anything other than incidental aspects of ordinary commercial life.
