Understanding Penalties and Human Rights Under Article 6 of ECHR

How Article 6 Affects Some Welsh Revenue Authority Penalties

Some Welsh Revenue Authority penalties are civil under UK tax law but may still be treated as “criminal” for human rights purposes. When that happens, Article 6 of the European Convention on Human Rights can give the taxpayer extra procedural protections, including fair process, prompt notice of the allegation, and protection against self-incrimination.

• A penalty does not have to be criminal under UK law for Article 6 to apply; some civil tax penalties can still count as “criminal” under human rights law.
• Penalties linked to deliberate behaviour are a key example of cases that may engage Article 6.
• If Article 6 applies, the taxpayer should be told promptly what is alleged, why the penalty is being considered, and should have a fair and public hearing within a reasonable time if there is a hearing.
• The right not to self-incriminate can be important, especially where WRA is investigating deliberate conduct.
• WRA says it will notify the taxpayer if it believes the penalty being considered is likely to engage Article 6.
• The main difficulty is that a penalty can be civil in domestic tax law but treated as criminal for human rights procedure, so each case must be assessed by its nature and the relevant case law, not just its label.

How Article 6 human rights protections affect some Welsh Revenue Authority penalties

This page explains why some tax penalties, although civil under UK law, are treated as “criminal” for human rights purposes. That matters because Article 6 of the European Convention on Human Rights can give the taxpayer extra procedural protections when the Welsh Revenue Authority, or WRA, is considering whether to impose such a penalty.

What this rule is about

The source material deals with the interaction between tax penalties and the Human Rights Act 1998. That Act brings Article 6 of the European Convention on Human Rights into UK law.

Article 6 is mainly concerned with fairness when a public authority is deciding whether a person should face a charge or penalty of a criminal character. In tax, this can matter even where the penalty is not a criminal offence in domestic law. A penalty can still be treated as “criminal” for Convention purposes because of its nature or seriousness.

The practical point is that WRA cannot look only at the label used in UK tax law. Even if the penalty is described as a civil penalty, Article 6 may still apply.

What the official source says

The official material says that certain penalties are defined by the Convention and case law as “criminal” penalties. It gives penalties imposed because of deliberate behaviour as an example.

It also makes two important points:

• These penalties are not criminal under UK law. They remain civil tax penalties in the domestic legal system.
• Even so, they are treated as “criminal” for the purposes of the European Convention on Human Rights.

Where Article 6 is engaged, the taxpayer is entitled to certain safeguards. The source lists these as including:

• being informed promptly of the nature of, and reason for, the charge
• a fair and public hearing within a reasonable time
• the right not to self-incriminate

The source also says that if WRA believes a penalty under consideration is likely to engage Article 6, it will notify the person who may be liable to the penalty.

What this means in practice

The main practical effect is procedural fairness. If WRA is considering a penalty of the kind that may engage Article 6, the taxpayer should be told that this is so. That notification matters because it signals that the case is being treated as one that may attract enhanced safeguards.

This does not mean the taxpayer is facing a criminal prosecution in the ordinary UK sense. The penalty remains part of the civil tax system. But WRA must still respect the relevant Article 6 protections.

One practical consequence concerns information gathering and responses. Because the source specifically mentions the right not to self-incriminate, cases involving deliberate behaviour need particular care. The taxpayer should understand what is being alleged and why, and should be aware that the way evidence is obtained and used may matter.

Another consequence is timing and process. If Article 6 applies, the case should be handled in a way that is fair and completed within a reasonable time. If there is a hearing, Article 6 recognises an entitlement to a fair and public hearing.

How to analyse it

A sensible way to approach this issue is to ask the following questions:

• What penalty is WRA considering?
• Is it the sort of penalty that may be treated as “criminal” for Convention purposes?
• Does the allegation involve deliberate behaviour or another feature suggesting Article 6 may be engaged?
• Has WRA told the taxpayer that Article 6 is likely to apply?
• Has the taxpayer been told promptly what is alleged and why?
• Is the process being handled fairly and within a reasonable time?
• Are there any concerns about requiring the taxpayer to provide information that may amount to self-incrimination?

The source does not set out a full legal test for deciding when a penalty is “criminal” for Convention purposes. It refers generally to the Convention and case law. So the analysis is not just about reading the tax legislation. It also depends on the human rights classification of the penalty.

Example

Illustration: WRA is considering a penalty on the basis that a taxpayer acted deliberately in relation to a land transaction tax matter. Under UK tax law, that penalty is still a civil penalty. But because penalties linked to deliberate behaviour may be treated as “criminal” for Article 6 purposes, WRA should recognise that Article 6 may apply. The taxpayer should be told the nature of the allegation and the reason for it, and the case should be handled in a way that respects the taxpayer’s Article 6 rights.

Why this can be difficult in practice

The difficulty is that there are two legal lenses operating at once. Domestic tax law may call the penalty civil, while human rights law may treat it as criminal for procedural purposes. That can be confusing for taxpayers and advisers.

There is also a judgement element in deciding whether Article 6 is engaged. The source does not say that every penalty attracts Article 6. It says certain penalties do, and refers to Convention case law. So the answer may depend on the character of the penalty, not just its label.

The right not to self-incriminate can also create practical tension in tax enquiries, especially where the authority is investigating behaviour said to be deliberate. The source does not explain the full limits of that right in the tax context, so care is needed not to assume either that the taxpayer never has to respond, or that WRA can ignore Article 6 concerns.

Key takeaways

• Some tax penalties can be civil in UK law but “criminal” for Article 6 human rights purposes.
• Where Article 6 is engaged, the taxpayer has important procedural protections, including being told the case against them and protection against self-incrimination.
• WRA says it will notify the person concerned if it believes the penalty under consideration is likely to engage Article 6.
