Human rights arguments can be a useful tool in challenging tax penalties, either on their own or to support technical grounds, but are often an afterthought. In light of the Tax Tribunal’s consideration of human rights arguments in a few recent decisions, Anastasia Nourescu reviews the main protections offered by the European Convention on Human Rights (ECHR) and considers how tax penalties can be successfully challenged on the basis that they breach a taxpayer’s human rights.

The link between tax and human rights seems tenuous at first glance, which may be why human rights arguments are often overlooked in tax cases. However, as tax penalties can be substantial and carry other implications for a taxpayer’s reputation, all grounds of challenge must be borne in mind, and human rights challenges can be surprisingly effective.


Application of human rights to tax matters

Two articles within the ECHR are relevant to tax:

  • Article 6, which is the right to a fair trial, and
  • Article 1 of the First Protocol (“A1P1”), which is the entitlement to the peaceful enjoyment of one’s possessions.

Before we dive in, let’s settle a question of semantics. Article 6 only applies to “criminal charges”. Penalties imposed by HMRC in relation to tax assessments are civil penalties that can be challenged before the Tax Tribunal. However, human rights law has its own definitions of what is “civil” and what is “criminal”. It is widely accepted that tax penalties constitute “criminal charges” for the purposes of Article 6, which protects a person’s right to a fair trial (see Jussila v Finland [2009] STC 29).

The protection of Article 6 does not extend to the underlying tax assessments, which are considered to be civil matters (see Ferrazzini v Italy [2001] STC 1314). All tax matters (including assessments and penalties) can be challenged on human rights grounds under A1P1 (see NKM v Hungary [2013] STC 1104). However, this article will focus on tax penalties.


Article 6: Right to a fair trial

Article 6 is designed to protect a person’s right to a fair trial. As recently confirmed by the Upper Tribunal in CF Booth Ltd v Commissioners for HM Revenue and Customs [2022] UKUT 217 (TCC), deciding whether there has been a breach will require a broad assessment based on “the nature of the issue to be tried, its seriousness and all the circumstances of the individual case”. However, there are a few specific Article 6 protections that apply across the board, including the following:

  1. The right to silence. After HMRC has reached a view on the tax position, it may ask the taxpayer for specific information that will enable HMRC to decide whether to issue penalties. However, under the right not to self-incriminate, the information must only be provided if it already exists in documentary form. HMRC cannot require a taxpayer to answer questions or prepare new documents.
  2. The right to obtain professional advice. A taxpayer wishing to seek advice should inform HMRC and ask for time to do so, for example, by extending the time for compliance with an information request or the deadline for appealing against the penalty. Financial assistance may also be available to help the taxpayer with an appeal to the First-tier Tribunal.
  3. The right to a review or appeal against the penalty. A taxpayer can ask for a review of or appeal against the penalty to be considered together with any review of or appeal against the underlying tax assessment. However, unlike in a tax appeal, in a penalty appeal, the burden of proof will be on HMRC.
  4. The right to be informed promptly of the penalty and to have a hearing within a reasonable time. HMRC must inform taxpayers that they may be liable to penalties as soon as it has reason to believe a penalty may be due.

The last of these can be particularly relevant, as HMRC sometimes takes a long time to issue a penalty. In that case, Article 6 will be breached if HMRC fails to notify the taxpayer of the penalty within a reasonable time of being “charged”. But at what point is a taxpayer subject to a “charge” for these purposes? Generally speaking, a taxpayer will normally be taken to have been “charged” when they are notified that a penalty is being considered by HMRC. The delay will then be judged to be reasonable or unreasonable depending on the length of time HMRC takes from that point, and the circumstances of the case. That said, the time of charge might be earlier in a given case. In King v United Kingdom (No. 2) [2004] STC 911, the ECHR held that the charge arose when HMRC warned the taxpayer of potential criminal liability.  In this case, the criminal prosecution was not actually pursued, but a penalty was subsequently charged.  The date of the “charge” was held to be the date on which HMRC warned the taxpayer of the criminal liability rather than the penalty.

Once it has been established that there has been a breach of Article 6, an appropriate remedy will have to be granted. This will depend on the facts of the case. When considering whether to bring a challenge on human rights grounds, the objective will usually be to set aside the penalty. However, establishing a breach will not automatically mean the penalty will be set aside and any appeal against it will succeed. The penalty will only be set aside if it is prejudicial (see Attorney General’s Reference (No. 2 of 2001) [2003] UKHL 68). The issue to be determined is whether there can no longer be a fair hearing of the penalty appeal or whether it would be unfair to proceed to trial in view of the delay. It is possible, for example, for a taxpayer to argue that an HMRC delay was prejudicial because relevant documents are no longer available or witnesses are no longer able to give evidence in the taxpayer’s favour.

In summary, in deciding whether to pursue an Article 6 argument against a penalty, the following questions will have to be answered:

  1. When was the taxpayer “charged”, ie when were they notified that a penalty was envisaged?
  2. How much time passed between the “charge” and the issuing of the penalty, and can that be said to be reasonable?
  3. Did the delay prejudice the taxpayer?
  4. What is the appropriate remedy? Must the penalty be set aside, or can the breach be remedied by, for example, expediting the appeal against the penalty?


A1P1: Right to peaceful enjoyment

A1P1 is designed to protect the peaceful enjoyment of a person’s possession. It states that “[n]o one shall be deprived of his possessions except in the public interest and subject to the conditions provided for by law and by the general principles of international law”. However, A1P1 allows a state to “enforce such laws as it deems necessary to control the use of property in accordance with the general interest or to secure the payment of taxes or other contributions or penalties”. It is clear that A1P1 cannot be used as support for a general argument against taxation but may be deployed to challenge specific tax decisions and penalties.

The imposition of a tax penalty will always result in interference with the taxpayer’s possessions. However, the question is whether such deprivation is justified in the public interest. In Lindsay v Customs and Excise Commissioners [2002] EWCA Civ 267, Lord Phillips of Worth Matravers, Master of the Rolls, held that there must be “a reasonable relationship of proportionality between the means employed and the aim pursued”.

The proportionality exercise was later summarised by Lord Reed in Bank Mellat v HM Treasury (No. 2) [2013] UKSC 39 as “whether, balancing the severity of the measure’s effects on the rights of the persons to whom it applies against the importance of the objective, to the extent that the measure will contribute to its achievement, the former outweighs the latter”.

Lord Sumption’s judgment is also worth noting, as it summarises the test for A1P1 based on principles derived from case law: “The question depends on an exacting analysis of the factual case advanced in defence of the measure, in order to determine (i) whether its objective is sufficiently important to justify the limitation of a fundamental right; (ii) whether it is rationally connected to the objective; (iii) whether a less intrusive measure could have been used; and (iv) whether, having regard to these matters and to the severity of the consequences, a fair balance has been struck between the rights of the individual and the interests of the community.”

It is also well-established that states have a wide margin of appreciation for the enforcement of tax. This was most recently confirmed in JP Whitter (Water Well Engineers) Limited v Commissioners for HM Revenue and Customs [2018] UKSC 31.

The aim of the legislation will depend on the specific penalty regime, but it will largely be to incentivise taxpayers to comply with their obligations and to penalise those who fail to do so. The tribunal has held this to be a legitimate aim, so the argument will most likely turn on whether issuing a penalty is a proportionate means of achieving that aim. For example, in Barry Edwards v Commissioners for HM Revenue and Customs [2019] UKUT 131 (TC), the Upper Tribunal recently considered an A1P1 argument in relation to the penalty regime under Schedule 55 to the Taxes Management Act 1970. It held that “the regime establishes a fair balance between the public interest in ensuring that taxpayers file their returns on time and the financial burden that a taxpayer who does not comply with the statutory requirement will have to bear”.

In summary, when mounting an A1P1 challenge to a penalty, the following points must be addressed:

  1. whether the aim of the penalty regime is a legitimate aim in the public interest, and
  2. whether there is a reasonable relationship of proportionality between the aim of the penalty regime and the requirements of the protection of the taxpayer’s rights.


Practical tips

The following practical considerations should be borne in mind:

  • Companies have human rights too: The “human” element of human rights may suggest that they only apply to individuals. However, corporates are also entitled to a fair trial and the peaceful enjoyment of their possessions. All taxpayers can deploy human rights arguments.
  • Factsheet CC/FS9: HMRC always issues factsheet CC/FS9, “The Human Rights Act and penalties”, when it is considering issuing a penalty. This includes an accessible summary of taxpayers’ rights under Article 6 and what to expect when challenging a penalty.
  • Alternative argument: It is not uncommon for a human rights argument to be raised as an alternative to or to complement another argument. For example, in CF Booth, the main ground of challenge was that a finding that the taxpayer knew its transactions were connected with fraud did not mean its behaviour had been deliberate; a ground based on Article 6 was presented in the alternative.
  • Naming and shaming: Taxpayers are often concerned about the wider implications of a penalty in addition to the financial implications. If a penalty is raised in relation to alleged deliberate conduct, HMRC may publish the taxpayer’s details in its list of deliberate tax defaulters unless it is successfully challenged. It is worth considering the implications of challenging versus simply paying a penalty.


The future

There has been much debate in recent years about changing how human rights apply in domestic law. In June 2022, the Bill of Rights Bill was introduced to parliament with the aim of repealing and replacing the Human Rights Act 1998. While the bill still allowed ECHR rights to be enforced in domestic courts, it imposed certain limitations. For example, the court would no longer have a duty to interpret legislation compatibly with the ECHR. Also, there would be an additional requirement that claimants must show they have suffered or would suffer a significant disadvantage as a result of a breach of their rights. The bill has since been removed from the parliamentary timetable. It remains to be seen if it will be brought back and, if so, in what guise, and whether that will alter its application to tax penalties.
