“16.5 Accordingly: a) where a claimant acts reasonably in hiring a replacement vehicle at about the same cost as the avoided loss of profit, the court will not count the pennies and hold the claimant to the hypothetical loss of profit if it turns out to be a little lower; but b) where the cost of hire significantly exceeds the avoided loss of profit, the court will ordinarily limit damages to the lost profit. 16.6 Even where the cost of hire significantly exceeds the avoided loss of profit, the claimant may still succeed in establishing that he or she acted reasonably: a) First, any business must sometimes provide a service at a loss in order to retain important customers or contracts. For example, a chauffeur might not want to let down a regular client for fear of losing her. Equally, a self-employed taxi driver might risk being dropped by the taxi company that provides him with most of his work. Properly analysed, these are not, however, exceptions to the general rule since in such cases the claimant is really saying that, but for his or her actions in hiring a replacement vehicle, the true loss of profit would not have been limited simply to the pro rata loss calculated on the basis of the period of closure but that future trading would itself have been compromised. Again, claimants are not required to weigh these factors precisely, and a claimant who reasonably incurs what at first might appear to be disproportionate hire costs in order to avoid a real risk of greater loss, will usually be entitled to recover such hire costs from the tortfeasor.” b) Secondly, many professional drivers use their vehicles for both business and private purposes. Where such a claimant proves that he or she needed a replacement vehicle for private and family use, a claim for reasonable hire charges, even if in excess of the loss of profit that was avoided by hiring the replacement vehicle, will ordinarily be recoverable in the event that a private motorist would have been entitled to recover such costs. c) Thirdly, it might be reasonable for a professional driver to hire a replacement vehicle even though the cost of doing so was significantly more than the loss of profit because he simply could not afford not to work. The tortfeasor takes his victim as he finds him and impecunious self-employed claimants cannot be expected to be left without any income and forced to look to the state to provide for their families on the basis that they might eventually recover their loss of profit some months or years later. 17. Cases said to be in the third category identified above raise the same issues of impecuniosity as the courts are used to dealing with in respect of claims by private motorists to recover what would otherwise be disproportionate credit hire charges following the decision in Lagden v. O’Connor. Any claimant wishing to justify hire costs on this basis will therefore have to comply with the directions given by the court in respect of the disclosure of documents as to his or her income, outgoings, assets, liabilities and access to credit. Even where the claimant’s income is low, the court will not simply accept an assertion that he or she could not afford not to work without proper evidence of impecuniosity.”
