R v Inland Revenue Commissioners, ex p. Preston

Factual and Procedural Background

The Appellant, a former employee of Company A (a tax-scheme promoter), sold shares in Gymboon Ltd. between 1974 and 1977. His self-assessment returns for 1974-75 and 1975-76 claimed substantial loan-interest deductions and a capital loss, resulting in no income-tax liability. In 1978 a Revenue officer began enquiries but accepted the Appellant’s offer to withdraw the disputed deductions and losses. Capital gains tax of £7,302 was then assessed on the Gymboon share sale, and the file was closed.

Subsequent information in 1979, drawn from Gymboon’s 1977 accounts and wider investigations into a Rossminster “company-purchase” scheme, led the Respondent Commissioners to suspect that the Appellant had obtained an income-tax advantage falling within Part XVII of the Income and Corporation Taxes Act 1970 (“ICTA 1970”). In July 1982 they served an information notice under ICTA 1970 s.465 and, in September 1982, issued a statutory notification under s.460(6). After the Appellant’s statutory declaration denying liability, the statutory tribunal found a prima facie case for counteraction, and the Respondent Commissioners issued an additional assessment under s.460(3).

The Appellant sought judicial review, alleging that the 1978 correspondence estopped the Respondent Commissioners from reopening his affairs and that their later action constituted an abuse of power. Judge Woolf granted relief at first instance, but the Court of Appeal reversed that decision. The present judgment of the House of Lords (Judges Templeman, Scarman, Edmund-Davies, Keith of Kinkel and Brightman) dismisses the Appellant’s further appeal.

Legal Issues Presented

1. Whether the 1978 correspondence created a contract, representation or estoppel preventing the Respondent Commissioners from invoking ICTA 1970 Part XVII against the Appellant.
2. Whether the Respondent Commissioners’ 1982 decision to proceed under s.460 constituted “unfairness” amounting to an abuse of power susceptible to judicial review.
3. Whether delay between the discovery of potential avoidance (1979) and the issue of the s.460 notice (1982) rendered the decision an abuse of power.

Arguments of the Parties

Appellant's Arguments

• The 1978 correspondence was a binding agreement or representation that no further enquiries or assessments would be made concerning Gymboon transactions if the Appellant withdrew certain tax-relief claims; the Respondent Commissioners were estopped from reopening the matter.
• Invoking s.460 after that agreement was “unfair” and therefore an abuse of power, satisfying the threshold for judicial review established in earlier case law.
• The Respondent Commissioners delayed action until after statutory time limits had expired for the Appellant to revive his withdrawn claims, compounding the unfairness.

Respondent Commissioners' Arguments

• No binding contract or representation was ever made; the 1978 closure was based on incomplete information and did not preclude later action if new facts emerged.
• The commissioners have a statutory duty under ICTA 1970 s.460 to counteract tax advantages and cannot fetter that duty by private agreement.
• Any delay was attributable to the complexity of investigating avoidance schemes and the need for further documentary evidence; it did not amount to an improper motive or abuse of power.

Court's Reasoning and Analysis

Judge Templeman (with Judges Scarman, Edmund-Davies, Keith and Brightman concurring) held that:

• The 1978 correspondence did not contain any explicit or implicit promise that the Respondent Commissioners would never reopen assessments. The exchange merely reflected a pragmatic decision to forego an interview once certain claims were withdrawn, and was based on incomplete information supplied by the Appellant.
• The Respondent Commissioners have a statutory duty under ICTA 1970 s.460 to counteract tax advantages. They cannot contract out of that duty, nor can estoppel arise to prevent its exercise where material facts were unknown at the time of any alleged assurance.
• “Unfairness” is a viable ground for judicial review when it amounts to abuse of power (e.g., acting for an improper motive or reneging on a clear representation). However, enforcing a statutory duty is not unfair per se; exceptional circumstances must exist. None were found here.
• The delay from 1979 to 1982 did not evidence an improper purpose. The investigation was complex, staff resources were limited, and the crucial sale agreement draft was not obtained until July 1982. Without proof of deliberate delay to prejudice the Appellant, no abuse of power arose.
• Alternative statutory remedies (appeal to the Special Commissioners and the tribunal) remain available for the Appellant to contest the substantive s.460 assessment; judicial review is therefore inappropriate absent abuse of power.

Holding and Implications

APPEAL DISMISSED; COURT OF APPEAL ORDER AFFIRMED.

Immediate Effect: the additional assessment issued under ICTA 1970 s.460 stands, subject to the Appellant’s pending statutory appeal to the Special Commissioners.

Broader Implications: the judgment confirms that (1) the Inland Revenue remains amenable to judicial review, but (2) taxpayers must demonstrate exceptional unfairness amounting to abuse of power before the courts will restrain the exercise of statutory tax-collection duties. No new precedent was set; the decision applies established principles to the facts.
