When discounting defamation damages for imputations proved true, the discount must reflect the relative seriousness of the true imputations compared to the unjustified ones; a 50% discount is excessive where the true imputations are far less serious. A partnership defamed in the way of its business need not prove actual financial loss and may rely on the presumption of damage. Interest should be awarded on defamation damages unless there is good reason not to do so; the modest size of an award, the absence of actual economic loss, and the characterisation of damages as 'vindication damages' are not proper reasons to refuse interest. Unexplained delay in prosecution may justify reducing the period over which interest is calculated but does not justify refusing interest entirely.
