Revenue and Customs v NHS Lothian Health Board (Scotland)

Factual and Procedural Background

Company A (a Scottish health body) submitted a late claim under section 121 of the Finance Act 2008 seeking repayment of historic input Value Added Tax (VAT) incurred by its laboratories between 1 April 1974 and 30 April 1997. The claim originally exceeded £7 million but was later reduced to about £900,000.

Company B (the United Kingdom tax authority) rejected the claim in December 2010 on the basis that:

• the apportionment method between business and non-business activity was unexplained,
• Company A had not proved the VAT had never been recovered, and
• certain yearly figures appeared disproportionate.

Company A appealed. The First-tier Tribunal dismissed the appeal; the Upper Tribunal upheld that dismissal. On further appeal, the Inner House of the Court of Session set those decisions aside and ordered a rehearing. Company B then appealed to the Supreme Court of the United Kingdom, resulting in the present judgment.

Legal Issues Presented

1. Whether a taxpayer who has shown that some taxable activity occurred may rely on estimates and extrapolations to quantify historic input VAT in the absence of primary records.
2. Whether the “EU principle of effectiveness” obliges the tribunal to adopt a more flexible or proportionate standard of proof for historic VAT claims.
3. Whether any alleged fault by the State (e.g., document destruction or past legislative error) affects the evidential burden on the taxpayer.
4. Whether the Inner House erred in overturning concurrent findings of the First-tier and Upper Tribunals absent an identifiable error of law.

Arguments of the Parties

Company B’s Arguments (Appellant)

• The Inner House misstated the evidential findings and applied an incorrect, lenient standard of proof.
• The right to deduct VAT is inseparable from the obligation to prove the quantum; mere proof of some business activity is insufficient.
• The principle of effectiveness was misapplied; national rules requiring reliable evidence do not make claims “virtually impossible or excessively difficult.”
• No relevant State fault existed; Company A’s evidential problems stem from its own record-keeping.

Company A’s Arguments (Respondent)

• It is undisputed that some recoverable input VAT arose; the dispute concerns only quantification.
• Strict insistence on primary documentation after decades breaches the principle of effectiveness.
• State conduct, including the unlawful retroactive time-limit and destruction of older records, should shift the evidential balance in the taxpayer’s favour.
• The First-tier Tribunal should have employed a reasonable estimate (14.7 % business-use ratio) rather than rejecting the claim outright.

Court’s Reasoning and Analysis

The Court emphasised that the right to deduct VAT is conditional upon reliable proof of the amount incurred. Citing Vădan and Advocate General Kokott in Zipvit, it held that:

1. The taxpayer must produce invoices or equally persuasive evidence; otherwise no deduction arises.
2. The First-tier Tribunal was entitled to find that the single percentage (14.7 %) derived from 2006-2007 could not credibly be extrapolated across 23 earlier years without supporting data.
3. The principle of effectiveness prevents procedural barriers, but it does not compel tribunals to relax evidential standards or undertake their own forensic reconstruction.
4. No special weight attaches to alleged State fault: the United Kingdom had lawfully required taxpayers to keep records, and any document destruction by either party was not causally linked to the evidential gap.
5. The Inner House mischaracterised the First-tier Tribunal’s findings and applied an incorrect distinction between establishing entitlement and quantifying it.

Holding and Implications

APPEAL ALLOWED. The decision of the Inner House is set aside; the decisions of the First-tier Tribunal and Upper Tribunal dismissing Company A’s claim are restored.

Implications: Taxpayers pursuing historic VAT claims must substantiate both entitlement and quantum with reliable evidence; broad extrapolations will not suffice. The judgment re-establishes a stringent evidential threshold for similar pending claims (estimated at £38 million) and clarifies that the EU principle of effectiveness does not dilute national standards of proof.
