77 I noted in earlier discussion that the plaintiff seeks to support its case by reference to the reasoning in Hill v Van Erp (supra). However, I am not persuaded that the reasoning there has direct application to the circumstances of the present case, notwithstanding that a third party, not in any direct relationship with the professional adviser, was able to obtain relief in that case. First, for all the reasons identified by Dawson J, the duty of care that was said to be owed by a solicitor to the prospective beneficiary appears to be a special category within the decided cases. It is a situation in which, quite clearly, the duty owed by the solicitor to the client coincides with the supposed duty of care to the intended beneficiary. Furthermore, it is a case in which the solicitor has a degree of control over whether the third party will obtain the benefit in question, and the third party can therefore be regarded as being in a position of special vulnerability.
