3. (a) That's right. To claim damages for deceit, a plaintiff must be able to prove that they have suffered actual loss as a result of the misrepresentation. If they can do this, the plaintiff is entitled to damages sufficient to put them in the position they would have been in had they not relied on the false statement. This includes both immediate and consequential losses.
