- If a seller of goods does some positive act to deliberately conceal defects
 in goods, this may amount to misrepresentation. In Schneider v Heath
 (1813) a boat which was being sold was partly submerged by the seller
 to conceal a rotten hold.
- A half-true statement which is accurate as far as it goes, but which
 conveys a misleading impression by being incomplete may give rise to
 misrepresentation. In Dimmock v Hallett (1866) a seller of land stated
 that all the farms on an estate were let to tenants, but omitted to say add
 that the tenants had all given notice to leave.
- Changed circumstances may imply a duty to disclose facts, which would
 not be misrepresentations at all if nothing had been said originally about
 the matter. If a representor knows of a change in circumstances, and
 thereby knows that his originally true statement is now false, this may
 amount to a misrepresentation. This arose in With v O’Flanagan (1936)
 when a doctor wanted to sell his practice. He told a prospective buyer the
 current income, and then became ill. By the time the sale eventually took
 place, many of the clients had transferred to another practice, and the
 income was much less than originally stated. As the doctor did not revise his
 original statement it was held to be a misrepresentation. A similar situation
 arose in Esso v Mardon (see above) where the Esso representative did not
 revise his sales forecasts in light of the new siting of the petrol pumps.
- A fiduciary relationship may indicate that there is a duty to disclose
 facts. All of the situations above involve people meeting on relatively
 equal terms. In these situations there is only a duty to tell the truth, but
 no general duty to disclose. So if something is said, it must be true, but
 there is not a general duty to say anything at all. If a person sells a stereo
 system to another, they can simply make no claims at all about it, letting
 the buyer form their own opinion of whether it is good value. In some
 circumstances, however, where one party is in a position of
 responsibility towards the other, the law may consider there to be a
 fiduciary relationship between the two. Some examples are: parent and
 child, solicitor and client, trustee and beneficiary. In these situations
 there is a greater duty to disclose relevant facts than in ordinary
 relationships between average people. A failure to disclose relevant facts
 in these circumstances may lead to misrepresentation. An example of a
 fiduciary relationship is found in the following case, which, although it
 failed on a technicality, shows how a misrepresentation could arise. You
 may remember that in Esso v Mardon (page 168) the court found that the
 Esso expert owed a duty of care to Mr. Mardon, therefore finding that
 there had been a negligent misrepresentation.
