EU Referendum Brief 5: How would Brexit impact the UK’s involvement in EU policing and criminal law?

Professor Steve Peers

What impact does EU membership have on policing and criminal law in the UK – and what would be the impact of Brexit? I’ll give the shorter summary version of the answer to those questions first, followed by a longer more detailed version.

Summary

The UK had a veto over EU laws in this area adopted before the Treaty of Lisbon came into force (1 December 2009). Since then, it has had two opt-outs instead: a) it can opt in (or out) of any new EU law in this field adopted after that Treaty; and b) it could go back and opt out of any old EU laws which were adopted before that Treaty. The UK used the latter power to opt out of the majority of pre-Lisbon laws.

There are five main areas of EU criminal law and policing. One area is the definition of crime, where the UK has opted into a small number of EU laws on issues such as child abuse. A second area is criminal procedure, where the UK has opted into some EU laws on suspects’ rights and crime victims’ rights. These are basically domestic areas of law, and there’s no reason to think the UK would change its rules after Brexit.

However, the other three areas concern international cooperation, where it is impossible for any individual country to act alone. Those areas are: a) recognition of criminal decisions (on arrest warrants or gathering evidence, for instance); b) the exchange of police information; and c) EU agencies like Europol, the EU police intelligence agency.

On criminal law mutual recognition, there are other international rules on some of these issues – such as extradition – but they do not go as far as the EU rules. In some cases, there are no alternative international rules on the same issue. The UK could seek to negotiate a treaty with the EU on these issues, but the past precedents show that non-EU countries are able to negotiate only limited participation in these EU laws.

On EU agencies, non-EU countries can participate as associates, but this means a more limited involvement in each agency than they would have as EU Member States.

The UK’s involvement in police information exchange with the EU would also be subject to renegotiation if the UK left the EU. Again, past precedents show that non-EU countries are able to negotiate only limited participation in these EU laws. And if the UK did not continue to sign up to EU data protection laws fully, there would be difficult legal disputes that could limit the transfer of policing data to the UK’s law enforcement authorities from the EU.

It cannot be seriously argued that the UK has ‘lost control’ over its law enforcement and intelligence agency operations to the EU, given the UK’s opt-out, the focus of EU law on cross-border issues, and the lack of any EU law on intelligence issues.

Overall, a Brexit is very likely to lead to a significant reduction on cooperation in criminal and policing matters between the UK and the EU.

The details

First and foremost, while the EU has adopted a number of laws in this area, the UK only participates in some of those laws, and has an opt-out over future laws in this area too. This blog post will in turn: (a) describe the basics of EU law in this area, including the UK opt-out; (b) summarise the main EU laws in which the UK does (or does not) participate in; and (c) indicate what could happen in the event of ‘Brexit’. For a full academic treatment of these issues, see the fourth edition of my EU Justice and Home Affairs Law book (volume 2).

(a) The basics of EU policing and criminal law 

Before the entry into force of the Treaty of Lisbon (on 1 December 2009) police and criminal law matters were subject to a different legal framework from ordinary EU (or European Community) law. The powers of the EU institutions (Commission, European Parliament, EU Court) were more limited, and each Member State, including the UK, had a veto over all laws.

The Treaty of Lisbon repealed these special rules, bringing EU criminal and policing law into the general framework of EU law. From this point on, the usual rules of EU law have applied to this field, with a few exceptions. However, the key point for the UK is that in place of a veto, it got not just one but two opt outs from EU law in this field.

First, the UK can opt out of (or into) any individual EU laws on criminal law or policing proposed after the entry into force of the Treaty of Lisbon.

Secondly, the UK got the power to opt out of EU criminal laws which it had already agreed to before the entry into force of the Treaty of Lisbon. It could invoke this power as of 1 December 2014. The UK government used this to opt out of all but 35 of the EU criminal laws adopted before the Treaty of Lisbon. (See the discussion of that process here).

(b) Which EU criminal and policing laws does the UK apply?

EU criminal and policing law touches on five main issues:

(a)    substantive criminal law (ie the definition of crimes);

(b)   mutual recognition in criminal matters (ie applying another EU Member States’ criminal law decision, where there is a cross-border issue like gathering evidence in another EU country, or asking another country to hand over a fugitive to face a trial or serve a sentence);

(c)    harmonisation of criminal procedure;

(d)   exchange of police information; and

(e)   EU agencies.

The effect of the two sets of opt-outs is that the UK has been highly selective about the EU law in this area which it wishes to apply. Taking the five areas of law in turn, first of all the UK has opted out of almost all EU substantive criminal law. It is covered by the EU Directives adopted since the Lisbon Treaty defining offences relating to trafficking in persons, sexual abuse of children and attacks on information systems (a form of cyber-crime), but not by EU laws defining offences relating to terrorism, organised crime, fraud, drugs, market abuse by bankers, racism, or currency counterfeiting. 

Secondly, the UK is far more engaged in mutual recognition in criminal matters, in particular the flagship law on the European Arrest Warrant (EAW), which is a fast-track extradition system. The UK has also signed up to EU laws on:

(a)    mutual recognition of investigation orders (gathering physical evidence, or interviewing witnesses, in another EU country);

(b)   victim protection orders (where the victim of domestic violence moves to another EU country and wants a restraining order against her abuser to be transferred to that country when she moves there);

(c)    pre-trial supervision (so a criminal suspect can be released on bail to await trial on less serious offences back in Britain, rather than spend a long time in pre-trial detention in a foreign prison);

(d)   confiscation of assets and freezing orders (to ensure that the proceeds of crime held by alleged or convicted criminals in another EU country can be frozen pending trial, and seized if the suspect is convicted);

(e)   the effect of prior sentences or other judgments (so that previous criminal offences committed in another EU country are counted when assessing whether someone is a repeat offender); and

(f)     the transfer of prisoners and criminal sentences (simplifying the movement of foreign prisoners to jails in their EU country of origin, and recognizing fines imposed by a criminal court too – including any penalties imposed against companies for breach of criminal law).

Conversely, the UK has opted out of only one measure in this field, concerning the mutual recognition of probation and parole orders.

Thirdly, as regards the harmonisation of criminal procedure, the UK participates in the EU Directive on crime victims’ rights. However, the UK has only opted in to two of the six EU laws which set out criminal suspects’ procedural rights. In particular, it has opted into the laws on translation and interpretation, and giving suspects information on their rights; but it has opted out of laws on access to a lawyer, presumption of innocence, child suspects’ rights, and a proposed law on legal aid (not yet agreed).

Fourthly, the UK is particularly keen to participate in the exchange of police information. It participates in every significant measure in the field:

(a)    the Schengen Information System (information on wanted persons and stolen objects, including terrorist suspects under surveillance);

(b)   the Customs Information System (used particularly in drug trafficking cases);

(c)    the ‘Prum’ decisions (which give access to other EU countries’ police databases on fingerprints, licence plates and DNA); and

(d)   the laws on exchange of criminal records.

Finally, as regards EU agencies, the UK participates in Europol (the EU police intelligence agency) and Eurojust (the agency which coordinates work of prosecutors in cross-border cases) at present. However, it has opted out of a new law concerning Europol, and a proposed new EU law concerning Eurojust, which set out (or would set out) revised rules for those agencies following the entry into force of the Treaty of Lisbon, although it might decide to opt in to those Regulations after they are adopted. The UK used to host the European Police College (a training agency), but refused to continue hosting it and opted out of a new version of the relevant law.

There has been some concern particularly about the prospect of the UK participating in a law to create a European Public Prosecutor. While the EU Commission proposed a law to create a European Public Prosecutor in 2013, the UK has opted out of that proposal. Indeed, the UK would have to hold another referendum before it opted in to that law, according to the European Union Act 2011.

(c) What would the impact of ‘Brexit’ be?

It’s sometimes argued that EU laws on policing and criminal law are irrelevant to the UK’s membership of the EU, because the UK can simply do everything it wishes to do in this field in its domestic law. That’s a valid argument for two of the five areas of law described above: substantive criminal law and harmonisation of procedure. But it doesn’t work for the three other areas – mutual recognition, exchange of information and participation in EU agencies – which necessarily require some cooperation with other states. Put simply, a British Act of Parliament cannot regulate how France or Germany issue extradition requests.

What would happen if the UK left the EU? In each case, as with other areas of EU law and policy, it would depend on what the UK and EU negotiated afterward. But it is possible to give some general indication of the consequences.

In the area of mutual recognition, the UK can fall back on Council of Europe treaties, which address some of the same issues (note that the Council of Europe is a separate body from the EU, which includes non-EU European countries like Turkey and Russia; some of its treaties can be signed also by non-European states like the USA).

However, the relevant treaties do not go into as much detail as the EU laws, and are often less effective.  As an indication of this, see the UK government information about the application of EU law in this area. Extradition from the UK has gone from 60 people a year (to all countries) before 2004 to 7000 since 2004 on the basis of the European Arrest Warrant. Over 95% of those sent to other Member States are not British.

Moreover, in some cases the UK and/or some other Member States have not ratified the relevant treaties. For instance, fewer than half of all Member States have ratified the Council of Europe Convention on validity of criminal judgments; the UK has not ratified it either. But the EU law on mutual recognition of criminal penalties sets out rules on one of the key issues in that Council of Europe treaty: the recognition of criminal financial penalties imposed by another Member State’s court. Some issues have not been the subject of Council of Europe treaties at all, such as the pre-trial supervision rules set out in EU law. In these cases, the EU law is the only means of ensuring the cooperation in question.

Another alternative is to negotiate treaties with the EU on these issues.  The EU has been willing in practice to negotiate access to some aspects of its criminal law measures: a form of the EAW for Norway and Iceland, an extradition treaty with the USA, and mutual assistance (exchange of evidence) with Norway and Iceland, the USA and Japan. But the extradition treaty with Norway and Iceland took years to negotiate, is still not in force at time of writing, and does not oblige States to extradite their own citizens – meaning that the UK would not be able to ask Germany to extradite Germans, for example. That restriction cannot easily be negotiated away in the event of Brexit, because some EU countries have constitutional problems which prevent them extraditing their own citizens outside the EU. (On these sorts of issues, see E Guild, ed, Constitutional challenges to the European Arrest Warrant).

Overall, there are no such treaties agreed with any non-EU countries on the large majority of EU criminal law mutual recognition measures. Of the treaties which are agreed, not a single one goes as far as the relevant EU legislation in force.

A particular concern of critics of the EU rules on extradition is the ‘sufficient evidence’ (‘prima facie’) test which was traditionally applied by the UK before accepting an extradition request. While it is sometimes argued that the EAW abolished the ‘prima facie’ test as regards EU countries, this is not correct. In fact, the UK waived the right to apply this test to European countries when it signed up to the Council of Europe extradition treaty back in 1990, over a decade before it signed up to the EU’s EAW: see the Extradition Act 1989, section 9(4), which was implemented by the European Convention on Extradition Order 1990 (SI 1990 No. 1507). In other words, the test was not abolished because of EU law, but was already abolished well before the EU had any involvement in extradition law.

Why did the UK abolish the prima facie test? As noted in the 2011 Baker review of UK extradition law, the decision was made because of the difficulties it posed for extradition in practice: a White Paper of 1986 stated that it ‘did not offer a necessary safeguard for the person sought by the requesting State but was a formidable impediment to entirely proper and legitimate extradition requests’. Ultimately the Baker review recommended that there was ‘no good reason to re-introduce the prima facie case requirement’ where it had been abolished, and that ‘No evidence was presented to us to suggest that European arrest warrants are being issued in cases where there is insufficient evidence’.

The prima facie test is sometimes described as an aspect of the ‘presumption of innocence’, although in fact a fugitive who is extradited pursuant to this test still either has to be convicted pursuant to a trial in the requesting State, or has already been convicted but fled the country. In other words, the presumption of innocence still applies when the substantive criminal trial takes place (or took place).

As regards the EU agencies, the UK can enter into agreements to cooperate with Europol and Eurojust, like other non-EU countries. However, as the Director of Europol points out, such agreements don’t allow the UK to have direct access to databases, to lead investigation teams, or to take part in the management of those agencies: both Europol and Eurojust have had British Directors.

Finally, as regards policing, the EU has given some non-EU states access to the Schengen Information System, and to the ‘Prum’ rules on access to each Member State’s national policing databases. But this was linked to those countries fully joining the Schengen system. The UK would obviously not do that after a Brexit.

The EU has also signed treaties on the exchange of passenger name records with non-EU countries (the USA, Canada and Australia), as well as a treaty on the exchange of financial information (concerning alleged terrorists) with the USA, so might be willing to sign similar treaties with the UK. It has also recently agreed an ‘umbrella’ treaty on general exchange of police information with the USA, although this is not yet in force.

However, the EU has not extended access to its system on exchange of criminal records to any non-EU countries. While there is a Council of Europe treaty on mutual assistance in criminal matters (which the UK and all other Member States are party to) that provides for some exchange of information of such records, it results in far less information exchange. The exchange of criminal records is particularly important for the UK: the government has reported that the UK is one of the biggest users of the EU system, and that criminal records checks of foreign nationals in the criminal justice system have increased 1,650% since 2010.

However, there is a particular issue that has complicated the exchange of personal data between the EU and with non-EU countries, particularly as regards policing data. Are their data protection standards sufficient as compared to the standards maintained by the EU? If not, then the European Parliament may be reluctant to approve the deal, or it might be challenged in the EU Court. This isn’t a hypothetical possibility – it has happened several times already.

I have discussed this issue in more detail in a recent blog post for The Conversation, but I will summarise the main points there again. As regards deals between non-EU countries and the EU itself, the EU Court of Justice has struck down a Commission decision on the transfer of personal data to the USA, because there was insufficient examination of the data protection standards applied by US intelligence agencies as regards access to personal data on social media. A replacement deal is planned, but will also be challenged in court. A further case is pending, where the EU Court has been asked to rule on the legality of the most recent EU/Canada treaty on the exchange of passenger records data, to ascertain if it meets EU standards for data protection.   

If the UK left the EU, any UK/EU agreement on the transfer of personal data would have to meet the same requirements. Those requirements cannot simply be negotiated away, since they stem from the EU Charter of Rights – part of the primary law of the EU. The Charter can be amended, but to have legal effect the EU Treaties would also have to be amended to refer to that revised text. It is hard to believe this could happen at the behest of a country which has just left the EU.

Would UK legislation meet the test of being sufficiently similar to EU standards? The Court of Justice has been asked in the pending Davis and Watson case whether the rules on police access to personal data comply with the EU law that binds the UK as a Member State. Another Bill on this issue is pending before the UK Parliament, and would likely become an Act of Parliament before Brexit. Since many privacy campaigners are critical the draft Bill, there would almost certainly be similar legal challenges to transfers of personal data to and from the UK after Brexit, unless the UK agrees to continue fully applying EU data protection law.

(d) Arguments by the referendum campaigns

The official leaflet summarising the position of the two sides in the referendum campaign contains a number of relevant claims from each side. For the Remain side, the pamphlet says that the EAW ‘allows us to deport criminals from the UK and catch those fleeing justice across Europe’, and that EU membership helps to tackle ‘global threats like terrorism’. For the Leave side, the pamphlet says that the EU ‘will continue to control…vital security policies such as counter-terrorism’ and the EU Court ‘will keep taking powers over how our intelligence services fight terrorism’.

Are these claims valid? As for the first Remain claim, as noted above the statistics show that the number of persons extradited to and from the UK have indeed increased since the EAW has been applied – although some extradition would still take place even if the UK did not apply the EAW.

In light of the official UK government information referred to above, other operational cooperation via Europol and other forms of EU police and criminal law cooperation presumably has some impact on combating threats like terrorism and other serious crimes in practice. However, it is not possible to estimate their impact compared to purely national actions and other forms of international  cooperation.

As for the arguments by the Leave side, it is clear from the description of the laws which the UK applies that the EU does not ‘control…vital security policies’. The functioning of the UK law enforcement authorities is up to the UK, and there is no EU regulation of intelligence agencies. EU law impacts only cross-border issues.

As we have seen, the only EU case law to date impacting intelligence agencies concerns non-EU intelligence agencies. The ruling restricts transfers of data gathered by social networks to those non-EU countries in that context, unless those countries apply EU data protection law. If the UK left the EU, it would therefore be subject to the same restrictions on obtaining personal data in criminal cases from the EU. Leaving the EU is therefore more likely to impede UK intelligence agencies’ work, than it is to facilitate it. 

Conclusion

The UK’s participation in EU criminal and policing law has led to an increase in cooperation in areas such as extradition and the exchange of police information. In these cases, there are question marks about what would happen after Brexit – mainly political but to some extent legal too. In the event of Brexit, there is a very high likelihood that cooperation between the UK and the remaining EU would be reduced (although not to zero). And in light of the UK’s opt-outs and the limited effect of EU law on purely domestic matters, it cannot seriously be argued that UK law enforcement and intelligence agencies are ‘controlled by’ the EU.
