Omagh Minerals Ltd v Revenue & Customs (AGGREGATES LEVY : Aggregates Levy)

Factual and Procedural Background

The Respondents ("HMRC") assessed Company A in the sum of £304,290 for alleged arrears of aggregates levy relating to periods in 2008 and 2009 and imposed a penalty of £15,214.50 under Part 2 of Schedule 6 of the Finance Act 2001 ("FA 2001"). Company A appeals both the assessment and the penalty. HMRC also seeks ordinary interest of £4,454 related to the assessment. The dispute concerns rock extracted from Company A's opencast gold mine, with HMRC asserting the rock consisted of mica schist and quartz, which are not exempt from the aggregates levy under section 17(4) FA 2001, while Company A contends the rock was shale or slate and thus exempt.

This decision addresses a preliminary issue concerning whether the proceedings constitute criminal proceedings such that Article 6 of the European Convention on Human Rights (the Convention) applies. The substantive issue regarding the aggregates levy assessment and penalty remains to be concluded.

Legal Issues Presented

1. Whether the penalty imposed under paragraph 9 Schedule 6 FA 2001 constitutes a "criminal charge" within the meaning of Article 6 of the Convention.
2. Whether the assessment of aggregates levy itself engages Article 6 protections.
3. Whether, if the penalty is criminal in nature, the entire proceedings (including the assessment) should be treated as criminal proceedings for the purposes of Article 6.

Arguments of the Parties

Appellant's Arguments

• The penalty imposed by HMRC is criminal in nature based on the Engel criteria, despite being classified as civil under domestic law.
• The penalty is intended to be deterrent and punitive, distinguishing it from compensatory interest or assessment.
• Because the penalty is criminal in nature, Article 6 applies to the entire proceedings, including the assessment and interest, as these are intertwined.
• It is not possible to separate the penalty-related parts of the proceedings from the assessment parts since liability for all depends on whether the rock is exempt.
• Reference to the European Court of Human Rights (ECtHR) decisions in Ferrazzini v Italy and Jussila v Finland supports the application of Article 6 protections to the penalty and related proceedings.

Respondents' Arguments

• The assessment is a tax dispute concerning civil rights and obligations and does not engage Article 6.
• Under the Engel criteria, the penalty is not criminal but a civil penalty within the fiscal regime, as Parliament deliberately structured Schedule 6 FA 2001 with separate civil and criminal sanctions.
• The penalty is regulatory, preventative, and modest (fixed at a maximum of 5%), without the punitive severity typical of criminal sanctions.
• There are no arrests, detentions, convictions, or serious personal consequences, which are relevant factors in determining criminality.
• The assessment and penalty proceedings are separate; the assessment does not depend on the penalty, and challenges to assessments do not engage Article 6.
• There is no UK authority supporting the proposition that Article 6 protections extend to the entire proceedings when a penalty is criminal but the assessment is not.

Court's Reasoning and Analysis

The court applied the Engel criteria to determine whether the penalty imposed under paragraph 9 Schedule 6 FA 2001 constitutes a criminal charge under Article 6. Although the penalty is classified domestically as civil, this classification is only a starting point. The court emphasized the purpose of the penalty—to deter and punish underdeclaration of tax—indicating its criminal nature. The monetary amount or percentage (5%) of the penalty is not determinative of its character.

The court rejected the Respondents' argument that the penalty is regulatory rather than criminal, noting that deterrence and punishment are core to criminal charges under the Convention.

Regarding the assessment, the court followed the established precedent from Ferrazzini and others, holding that the assessment itself does not determine civil rights or criminal charges under Article 6 and thus is outside its scope.

On whether the entire proceedings (assessment and penalty) should be treated as criminal, the court distinguished this case from Georgiou, where penalty and assessment were inseparable. Here, the assessment is a conventional tax liability determination independent of the penalty, which is contingent upon the assessment but separable for Article 6 purposes.

The court concluded that Article 6 applies only to the penalty proceedings and not to the assessment or interest proceedings.

Holding and Implications

The court's final decision is as follows:

• The assessment does not engage Article 6 of the European Convention on Human Rights.
• The penalty imposed under paragraph 9 Schedule 6 FA 2001 constitutes a criminal charge for the purposes of Article 6.
• Article 6 applies only to the penalty proceedings and not to the entire proceedings including the assessment and interest.

The direct effect of this decision is that the appellant is entitled to the protections under Article 6 only in relation to the penalty. The assessment and interest proceedings remain outside the scope of Article 6 protections. No new precedent altering the established jurisprudence on tax assessments and penalties was set beyond the application of existing principles to the facts of this case.
