Collateral contracts
These are not strictly exceptions to privity, but have been used to circumvent
the privity rule.
Covenants which run with the land
A principle of land law provides another exception to the doctrine of
privity. In certain circumstances, covenants (or promises to do something)
imposed on land may ‘run with the land’. This means that the promises
attach themselves to the land, and go with it when it is sold to someone else.
The covenants are then enforceable against subsequent owners.
Privity of contract 137
NZ Shipping Co v Satterthwaite Co Ltd (1974) (The Eurymedon)
A contract was made between the plaintiffs and the defendant carriers
to ship a cargo from Liverpool to New Zealand, the bill of lading
containing various exemption clauses, including one which said that a
servant or agent of the carrier would not be liable for damage to the
cargo due to negligence in carrying out the work. The carriers then
contracted with stevedores to unload the cargo, and they damaged it
while unloading it. The plaintiffs argued that the stevedores could not
rely on the exemptions in the bill of lading because they were not party
to the contract, but it was held that the carriers were acting as agents
for the stevedores, so were treated as one party to the contract with the
plaintiffs.
Shanklin Pier Ltd v Detel Products Ltd (1951)
The plaintiffs, who owned Shanklin pier on the Isle of Wight,
contracted with painters to paint the pier. The plaintiffs required
assurance over the quality of the paint, so the painters agreed with
Detel that they would buy Detel paint if Detel gave a warranty to the
plaintiffs that it would last for seven to ten years. The painting went
ahead on this basis, but the paint only lasted for three months. A
problem of privity arose in that Detel had given assurance to the
plaintiffs, but it was the painters who had made the contract to buy the
paint. It was held that the pier owners could sue the paint manu-
facturers on a collateral contract, thus providing a remedy but avoiding
the issue of privity.
