McKnight v Sheppard (Sheppard v McKnight)

Legal expenses incurred in defending disciplinary proceedings are deductible from trading profits where their exclusive purpose is to preserve the trade from destruction. A personal benefit, such as protecting reputation, is an effect rather than a separate purpose unless it was also an object of the expenditure.

The punitive policy which prevents deduction of a fine does not extend automatically to defence costs. Allowing those costs does not undermine disciplinary policy. Refusing deduction could impose an additional penalty and conflict with the fundamental entitlement of every person, whether guilty or innocent, to defend themselves.

A stockbroker incurred approximately £200,000 in defending disciplinary charges before Stock Exchange committees. Some charges were upheld and fines totalling £50,000 were imposed. The Special Commissioner found that the stockbroker's exclusive purpose in paying the legal expenses was to preserve his sole-trader business, which expulsion or suspension would have destroyed.

The Special Commissioner allowed deduction of the legal expenses under Case I of Schedule D but disallowed the fines. Lightman J allowed the Revenue's appeal concerning the expenses. The Court of Appeal restored the Commissioner's decision, and the Revenue appealed to the House of Lords. The issue was whether Income and Corporation Taxes Act 1970, section 130(a), excluded the expenses because they were not laid out wholly and exclusively for the purposes of the trade.

1. Appeal dismissed unanimously. Lord Hoffmann delivered the leading speech. Lord Mackay of Clashfern, Lord Clyde, Lord Hutton and Lord Hobhouse of Woodborough agreed with his reasons.

2. Per Lord Hoffmann, the Special Commissioner was entitled to find that the taxpayer's sole purpose in incurring the legal expenses was to preserve his trade. Although a successful defence would also protect his personal reputation, purpose must be distinguished from effect. Awareness of a private advantage does not make that advantage an object of the expenditure. The finding of an exclusively professional purpose was therefore consistent with the Commissioner's other factual findings.

3. The relevant question on an appeal by case stated was whether the Commissioner's conclusion was legally open on the facts found. The Commissioner's conclusion satisfied that standard. The principle in Morgan v Tate & Lyle Ltd [1955] AC 21 applied because expenditure exclusively incurred to preserve a trade from destruction may be wholly and exclusively expended for its purposes.

4. Per Lord Hoffmann, a fine is ordinarily non-deductible because its purpose is to punish the taxpayer. Permitting deduction could dilute the legislative or regulatory policy by sharing the punishment with the community through tax relief. That specific policy justified disallowing the Stock Exchange fines, although the taxpayer no longer challenged that conclusion.

5. The same reasoning did not prevent deduction of the legal expenses. The nature and policy of defence costs differ from those of a fine. Their purpose does not change according to whether the defence succeeds, fails, succeeds on some charges, or mitigates the penalty. It is fundamental that everyone, whether guilty or innocent, may defend themselves. No clear disciplinary policy was infringed by allowing the expenses, while disallowance would effectively add a penalty not imposed by the regulatory scheme.

1. House of Lords: Dismissed the Revenue's appeal unanimously and upheld the deductibility of the legal expenses.

2. Court of Appeal: Nourse, Potter and Mummery LJJ allowed the taxpayer's appeal concerning the legal expenses.

3. High Court: Lightman J allowed the Revenue's appeal concerning the legal expenses and dismissed the taxpayer's appeal concerning the fines.

4. Special Commissioner: Allowed deduction of the legal expenses under Case I of Schedule D but disallowed deduction of the fines.
