However, because the heart of the battle on this issue in the court below centred on whether the undertaking had been given at all, rather than on what specific steps Mr Rajaram ought to have taken when faced with such an undertaking, the case that Mr Xavier put before us, namely that Mr Rajaram ought to have addressed his mind to and then advised Mr Devineni on the specific issues arising from the undertaking as we have articulated above, was not squarely put to Mr Rajaram in the proceedings below. This meant that the precise nature of the duty that Mr Rajaram was said to be under, and consequently, the precise communications that did or did not take place between Mr Rajaram and his Indonesian counterparts in discharging any such duty with respect of the oral undertaking, were not explored in any meaningful way at trial. In these circumstances, we consider that it would not have been open to the Judge, even if he had framed the duty more specifically, to make a finding that Mr Rajaram had breached his duty to advise on the oral undertaking in the manner and to the extent we have outlined above. Nor, obviously, is it open to us to do so. For these reasons, we allow the defendants’ appeal in CA 133/2015.
