X wrote to his solicitors (D) asking them to change his will so as to give £9,000 to each of his daughters but, due to the solicitors’ inefficiency, they failed to do this before, a few months later, X died. The daughters (P) sued D in tort. HL allowed their claim, accepting that it contradicted the privity rule but said that this claim had to be allowed in the interests of justice and avoiding a “legal black hole” of rights.
