"In the light of this common knowledge shared by BT and Raine
and Horne of the proposed use of the valuation, BT argued that the
second part of the clause must be understood as disclaiming
responsibility to any third party suffering damage by reason of
the third party using the valuation, but not as disclaiming
responsibility for damage resulting to a third party by the very
use of the valuation by BT for which Raine and Horne in the first
part of the clause impliedly accepted responsibility. This use,
to the knowledge of Raine and Horne, was used by BT in discharging
its duties to third parties so that they, rather than BT, would
in the nature of things be the likely sufferers from an incorrect
valuation. In my view this is a reasonable reconciliation of
the two parts of the clause. The wide interpretation of the second
part contended for by Raine and Horne would, in the circumstances,
mean that Raine and Horne was accepting no real responsibility at
all for its valuation, despite the fact that it was providing
the valuation as a matter of contractual obligation in the course
of its business for a negotiated fee, and despite the fact that
the first part of the clause itself contemplated that Raine and
Horne would be responsible for the valuation in so far as it was
used by BT.
The disclaimer clause was unilaterally framed and inserted by
Raine and Horne, and if it was intended to disclaim responsibility
for the consequences of its use for the very purpose for which
it was obtained, it was reasonable to expect Raine and Horne to
say so in clear words. In saying this I am mindful of the comments
of Lord Reid in Hedley Byrne (at 492) where he contrasted
disclaimer clauses in contracts, where it was necessary to exclude
liability for negligence, and the disclaimer in the case before
him, where the question was whether an undertaking to assume a
duty to take care could be inferred. While in the present case
the contractual liability would not extend to third parties, the
obligation to provide the valuation was being undertaken in a
contractual context where responsibility to take care was being
assumed to BT, and where, in my view, it would be reasonable to
infer that the responsibility so assumed would extend in tort
beyond the other party to the contract to the third plaintiffs,
in the discharge of duties towards which BT proposed to use the
valuation."
