(Police and judicial cooperation in criminal matters – Articles 6(2) EU and 34(2)(b) EU – Framework Decision 2002/584/JHA – European arrest warrant and surrender procedures between Member States – Approximation of national laws – Removal of verification of double criminality – Validity)

Opinion of Advocate General Ruiz-Jarabo Colomer delivered on 12 September 2006

Judgment of the Court (Grand Chamber), 3 May 2007

Summary of the Judgment

1.     *Preliminary rulings – Jurisdiction of the Court – Police and judicial cooperation in criminal matters*

*(Arts 34(2)(b) EU and 35(1) EU)*

2.     *European Union – Police and judicial cooperation in criminal matters – Approximation of the laws and regulations of the Member
States with regard to judicial cooperation in criminal matters*

*(Art. 34(2) EU; Council Framework Decision 2002/584, Art. 31(1))*

3.     *European Union – Police and judicial cooperation in criminal matters – Framework Decision on the European arrest warrant and
the surrender procedures between Member States*

*(Council Framework Decision 2002/584, Arts 1(3) and 2(2))*

4.     *European Union – Police and judicial cooperation in criminal matters – Framework Decision on the European arrest warrant and
the surrender procedures between Member States*

*(Council Framework Decision 2002/584, Art. 2(2))*

1.     Under Article 35(1) EU, the Court has jurisdiction, subject to the conditions laid down in that article, to give preliminary
rulings on the interpretation and validity of, inter alia, framework decisions, which necessarily implies that it can, even
if there is no express power to that effect, be called upon to interpret provisions of primary law, such as Article 34(2)(b)
EU where the Court is being asked to examine whether a framework decision has been properly adopted on the basis of that latter
provision.

(see para. 18)

2.     Framework Decision 2002/584 on the European arrest warrant and the surrender procedures between Member States, which provides
for the approximation of the laws and regulations of the Member States with regard to judicial cooperation in criminal matters
and, more specifically, of the rules relating to the conditions, procedures and effects of surrender as between national authorities
convicted persons or suspects for the purpose of enforcing judgments or of criminal proceedings, was not adopted in breach
of Article 34(2)(b) EU.

In so far as it lists and defines, in general terms, the different types of legal instruments which may be used in the pursuit
of the objectives of the Union set out in Title VI of the EU Treaty, Article 34(2) EU cannot be construed as meaning that
the approximation of the laws and regulations of the Member States by the adoption of a framework decision under Article 34(2)(b)
EU cannot relate to areas other than those mentioned in Article 31(1)(e) EU and, in particular, the matter of the European
arrest warrant.

Furthermore, Article 34(2) EU also does not establish any order of priority between the different instruments listed in that
provision. While it is true that the European arrest warrant could equally have been the subject of a convention, it is within
the Council’s discretion to give preference to the legal instrument of the framework decision in the case where the conditions
governing the adoption of such a measure are satisfied.

This latter conclusion is not invalidated by the fact that, in accordance with Article 31(1) of the Framework Decision, the
latter was to replace from 1 January 2004, only in relations between Member States, the corresponding provisions of the earlier
conventions on extradition set out in that provision. Any other interpretation unsupported by either Article 34(2) EU or by
any other provision of the EU Treaty would risk depriving of its essential effectiveness the Council’s recognised power to
adopt framework decisions in fields previously governed by international conventions.

(see paras 28-29, 37-38, 41-43)

3.     The principle of the legality of criminal offences and penalties (*nullum crimen, nulla poena sine lege*), which is one of the general legal principles underlying the constitutional traditions common to the Member States, has
also been enshrined in various international treaties, in particular in Article 7(1) of the European Convention on Human Rights.
This principle implies that legislation must define clearly offences and the penalties which they attract. That condition
is met in the case where the individual concerned is in a position, on the basis of the wording of the relevant provision
and with the help of the interpretative assistance given by the courts, to know which acts or omissions will make him criminally
liable.

In so far as it dispenses with verification of the requirement of double criminality in respect of the offences listed in
that provision, Article 2(2) of Framework Decision 2002/584 on the European arrest warrant and the surrender procedures between
Member States is not invalid on the ground that it infringes the principle of the legality of criminal offences and penalties.
The Framework Decision does not seek to harmonise the criminal offences in question in respect of their constituent elements
or of the penalties which they attract. While Article 2(2) of the Framework Decision dispenses with verification of double
criminality for the categories of offences mentioned therein, the definition of those offences and of the penalties applicable
continue to be matters determined by the law of the issuing Member State, which, as is, moreover, stated in Article 1(3) of
the Framework Decision, must respect fundamental rights and fundamental legal principles as enshrined in Article 6 EU, and,
consequently, the principle of the legality of criminal offences and penalties.

(see paras 49-50, 52-54)

4.     In so far as it dispenses with verification of double criminality in respect of the offences listed therein, Article 2(2)
of Framework Decision 2002/584 on the European arrest warrant and the surrender procedures between Member States is not invalid
inasmuch as it does not breach the principle of equality and non-discrimination.

With regard, first, to the choice of the 32 categories of offences listed in that provision, the Council was able to form
the view, on the basis of the principle of mutual recognition and in the light of the high degree of trust and solidarity
between the Member States, that, whether by reason of their inherent nature or by reason of the punishment incurred of a maximum
of at least three years, the categories of offences in question feature among those the seriousness of which in terms of adversely
affecting public order and public safety justifies dispensing with the verification of double criminality. Consequently, even
if one were to assume that the situation of persons suspected of having committed offences featuring on the list set out in
Article 2(2) of the Framework Decision or convicted of having committed such offences is comparable to the situation of persons
suspected of having committed, or convicted of having committed, offences other than those listed in that provision, the distinction
is, in any event, objectively justified.

With regard, second, to the fact that the lack of precision in the definition of the categories of offences in question risks
giving rise to disparate implementation of the Framework Decision within the various national legal orders, suffice it to
point out that it is not the objective of the Framework Decision to harmonise the substantive criminal law of the Member States
and that nothing in Title VI of the EU Treaty makes the application of the European arrest warrant conditional on harmonisation
of the criminal laws of the Member States within the area of the offences in question.

**Judgment**

1       The reference for a preliminary ruling concerns the assessment as to the validity of Council Framework Decision 2002/584/JHA
of 13 June 2002 on the European arrest warrant and the surrender procedures between Member States (OJ 2002 L 190, p. 1) (‘the
Framework Decision’).

2       This reference has been submitted in the course of an action brought by Advocaten voor de Wereld VZW (‘Advocaten voor de Wereld’)
before the Belgian Arbitragehof (Court of Arbitration) and seeking the annulment of the Belgian Law of 19 December 2003 on
the European arrest warrant (*Belgisch Staatsblad* of 22 December 2003, p. 60075) (‘the Law of 19 December 2003’), in particular Articles 3, 5(1) and (2) and 7 thereof.

**Legal context**

3       Recital (5) in the preamble to the Framework Decision provides:

‘The objective set for the Union to become an area of freedom, security and justice leads to abolishing extradition between
Member States and replacing it by a system of surrender between judicial authorities. Further, the introduction of a new simplified
system of surrender of sentenced or suspected persons for the purposes of execution or prosecution of criminal sentences makes
it possible to remove the complexity and potential for delay inherent in the present extradition procedures. Traditional cooperation
relations which have prevailed up till now between Member States should be replaced by a system of free movement of judicial
decisions in criminal matters, covering both pre-sentence and final decisions, within an area of freedom, security and justice.’

4       Recital (6) in the preamble to the Framework Decision is worded as follows:

‘The European arrest warrant provided for in this Framework Decision is the first concrete measure in the field of criminal
law implementing the principle of mutual recognition which the European Council referred to as the “cornerstone” of judicial
cooperation.’

5       Recital (7) in the preamble to the Framework Decision provides:

‘Since the aim of replacing the system of multilateral extradition built upon the European Convention on Extradition of 13 December
1957 cannot be sufficiently achieved by the Member States acting unilaterally and can therefore, by reason of its scale and
effects, be better achieved at Union level, the Council may adopt measures in accordance with the principle of subsidiarity
as referred to in Article 2 of the Treaty on European Union and Article 5 of the Treaty establishing the European Community.
In accordance with the principle of proportionality, as set out in the latter Article, this Framework Decision does not go
beyond what is necessary in order to achieve that objective.’

6       According to recital (11) in the preamble to the Framework Decision:

‘In relations between Member States, the European arrest warrant should replace all the previous instruments concerning extradition,
including the provisions of Title III of the Convention implementing the Schengen Agreement which concern extradition.’

7       Article 1 of the Framework Decision, which was adopted on the basis of Article 31(1)(a) and (b) EU and Article 34(2)(b) EU,
provides:

‘1. The European arrest warrant is a judicial decision issued by a Member State with a view to the arrest and surrender by
another Member State of a requested person, for the purposes of conducting a criminal prosecution or executing a custodial
sentence or detention order.

2. Member States shall execute any European arrest warrant on the basis of the principle of mutual recognition and in accordance
with the provisions of this Framework Decision.

3. This Framework Decision shall not have the effect of modifying the obligation to respect fundamental rights and fundamental
legal principles as enshrined in Article 6 of the Treaty on European Union.’

8       Article 2 of the Framework Decision provides:

‘1. A European arrest warrant may be issued for acts punishable by the law of the issuing Member State by a custodial sentence
or a detention order for a maximum period of at least 12 months or, where a sentence has been passed or a detention order
has been made, for sentences of at least four months.

2. The following offences, if they are punishable in the issuing Member State by a custodial sentence or a detention order
for a maximum period of at least three years and as they are defined by the law of the issuing Member State, shall, under
the terms of this Framework Decision and without verification of the double criminality of the act, give rise to surrender
pursuant to a European arrest warrant:

–        participation in a criminal organisation,

–       terrorism,

–       trafficking in human beings,

–       sexual exploitation of children and child pornography,

–       illicit trafficking in narcotic drugs and psychotropic substances,

–       illicit trafficking in weapons, munitions and explosives,

–       corruption,

–       fraud, including that affecting the financial interests of the European Communities within the meaning of the Convention of
26 July 1995 on the protection of the European Communities’ financial interests,

–       laundering of the proceeds of crime,

–       counterfeiting currency, including of the euro,

–       computer-related crime,

–       environmental crime, including illicit trafficking in endangered animal species and in endangered plant species and varieties,

–       facilitation of unauthorised entry and residence,

–       murder, grievous bodily injury,

–       illicit trade in human organs and tissue,

–       kidnapping, illegal restraint and hostage-taking,

–       racism and xenophobia,

–       organised or armed robbery,

–       illicit trafficking in cultural goods, including antiques and works of art,

–       swindling,

–       racketeering and extortion,

–       counterfeiting and piracy of products,

–       forgery of administrative documents and trafficking therein,

–       forgery of means of payment,

–       illicit trafficking in hormonal substances and other growth promoters,

–       illicit trafficking in nuclear or radioactive materials,

–       trafficking in stolen vehicles,

–       rape,

–       arson,

–       crimes within the jurisdiction of the International Criminal Court,

–       unlawful seizure of aircraft/ships,

–       sabotage.

3. The Council may decide at any time, acting unanimously after consultation of the European Parliament under the conditions
laid down in Article 39(1) of the Treaty on European Union (TEU), to add other categories of offence to the list contained
in paragraph 2. The Council shall examine, in the light of the report submitted by the Commission pursuant to Article 34(3),
whether the list should be extended or amended.

4. For offences other than those covered by paragraph 2, surrender may be subject to the condition that the acts for which
the European arrest warrant has been issued constitute an offence under the law of the executing Member State, whatever the
constituent elements or however it is described.’

9       Article 31 of the Framework Decision provides:

‘1. Without prejudice to their application in relations between Member States and third States, this Framework Decision shall,
from 1 January 2004, replace the corresponding provisions of the following conventions applicable in the field of extradition
in relations between the Member States:

(a)       the European Convention on Extradition of 13 December 1957, its additional protocol of 15 October 1975, its second additional
protocol of 17 March 1978, and the European Convention on the suppression of terrorism of 27 January 1977 as far as extradition
is concerned;

(b)      the Agreement between the 12 Member States of the European Communities on the simplification and modernisation of methods
of transmitting extradition requests of 26 May 1989;

(c)      the Convention of 10 March 1995 on simplified extradition procedure between the Member States of the European Union;

(d)      the Convention of 27 September 1996 relating to extradition between the Member States of the European Union;

(e)      Title III, Chapter 4 of the Convention of 19 June 1990 implementing the Schengen Agreement of 14 June 1985 on the gradual
abolition of checks at common borders.

2. Member States may continue to apply bilateral or multilateral agreements or arrangements in force when this Framework Decision
is adopted in so far as such agreements or arrangements allow the objectives of this Framework Decision to be extended or
enlarged and help to simplify or facilitate further the procedures for surrender of persons who are the subject of European
arrest warrants.

Member States may conclude bilateral or multilateral agreements or arrangements after this Framework Decision has come into
force in so far as such agreements or arrangements allow the prescriptions of this Framework Decision to be extended or enlarged
and help to simplify or facilitate further the procedures for surrender of persons who are the subject of European arrest
warrants, in particular by fixing time-limits shorter than those fixed in Article 17, by extending the list of offences laid
down in Article 2(2), by further limiting the grounds for refusal set out in Articles 3 and 4, or by lowering the threshold
provided for in Article 2(1) or (2).

The agreements and arrangements referred to in the second subparagraph may in no case affect relations with Member States
which are not parties to them.

Member States shall, within three months from the entry into force of this Framework Decision, notify the Council and the
Commission of the existing agreements and arrangements referred to in the first subparagraph which they wish to continue applying.

Member States shall also notify the Council and the Commission of any new agreement or arrangement as referred to in the second
subparagraph, within three months of signing it.

3. Where the conventions or agreements referred to in paragraph 1 apply to the territories of Member States or to territories
for whose external relations a Member State is responsible to which this Framework Decision does not apply, these instruments
shall continue to govern the relations existing between those territories and the other Member States.’

**The dispute in the main proceedings and the questions referred for preliminary ruling**

10     According to the decision making the reference, Advocaten voor de Wereld brought an action before the Arbitragehof on 21 June
2004 in which it sought the annulment, in whole or in part, of the Law of 19 December 2003 transposing the provisions of the
Framework Decision into Belgian law.

11     In support of its action, Advocaten voor de Wereld submits inter alia that the Framework Decision is invalid on the ground
that the subject-matter of the European arrest warrant ought to have been implemented by way of a convention and not by way
of a framework decision since, under Article 34(2)(b) EU, framework decisions may be adopted only ‘for the purpose of approximation
of the laws and regulations of the Member States’, which, it claims, is not the position in the present case.

12     Advocaten voor de Wereld also submits that Article 5(2) of the Law of 19 December 2003, which transposes Article 2(2) of the
Framework Decision into Belgian domestic law, infringes the principle of equality and non-discrimination in that, for the
offences mentioned in that latter provision, in the event of enforcement of a European arrest warrant, there is a derogation,
without objective and reasonable justification, from the requirement of double criminality, whereas that requirement is maintained
for other offences.

13     Advocaten voor de Wereld further argues that the Law of 19 December 2003 also fails to satisfy the conditions of the principle
of legality in criminal matters in that it lists, not offences having a sufficiently clear and precise legal content, but
only vague categories of undesirable behaviour. The judicial authority which must decide on the enforcement of a European
arrest warrant will, it submits, have insufficient information to determine effectively whether the offences for which the
person sought is being charged, or in respect of which a penalty has been imposed on him, come within one of the categories
mentioned in Article 5(2) of that Law. The absence of a clear and precise definition of the offences referred to in that provision,
it contends, leads to a disparate application of that Law by the various authorities responsible for the enforcement of a
European arrest warrant and, by reason of that fact, also infringes the principle of equality and non-discrimination.

14     The Arbitragehof points out that the Law of 19 December 2003 is the direct result of the Council’s decision to regulate the
subject-matter of the European arrest warrant by means of a framework decision. The heads of complaint invoked by Advocaten
voor de Wereld against that Law also hold good in equal measure with regard to the Framework Decision. In its view, differences
of interpretation between courts with regard to the validity of Community measures and the validity of the legislation which
constitutes the implementation of those measures in national law jeopardise the unity of the Community legal order and adversely
affect the general principle of legal certainty.

15     The Arbitragehof adds that, under Article 35(1) EU, the Court alone has jurisdiction to give a preliminary ruling on the validity
of framework decisions and that, under Article 35(2) EU, the Kingdom of Belgium has accepted the Court’s jurisdiction in this
field.

16     In those circumstances, the Arbitragehof decided to stay the proceedings and to refer the following questions to the Court
for a preliminary ruling:

‘1.      Is [the] Framework Decision ... compatible with Article 34(2)(b) of the [EU] Treaty, under which framework decisions may be
adopted only for the purpose of approximation of the laws and regulations of the Member States?

2.      Is Article 2(2) of [the] Framework Decision ..., in so far as it sets aside verification of the requirement of double criminality
for the offences listed therein, compatible with Article 6(2) of the [EU] Treaty ... and, more specifically, with the principle
of legality in criminal proceedings guaranteed by that provision and with the principle of equality and non-discrimination?’

**The questions referred for preliminary ruling**

*The first question*

 Admissibility

17     The Czech Government submits that the first question referred is inadmissible on the ground that it requires the Court to
examine Article 34(2)(b) EU, which is a provision of primary law not reviewable by the Court.

18     That argument is unfounded. Under Article 35(1) EU, the Court has jurisdiction, subject to the conditions laid down in that
article, to give preliminary rulings on the interpretation and validity of, inter alia, framework decisions, which necessarily
implies that it can, even if there is no express power to that effect, be called upon to interpret provisions of primary law,
such as Article 34(2)(b) EU where, as in the case in the main proceedings, the Court is being asked to examine whether a framework
decision has been properly adopted on the basis of that latter provision.

19     According to the Czech Government, the first question referred is also inadmissible inasmuch as the decision to refer fails
to indicate clearly the relevant grounds which would justify a finding that the framework decision is invalid. It submits
that it was for that reason impossible for it to submit any meaningful observations on that question. More specifically, in
so far as Advocaten voor de Wereld contends that the Framework Decision did not bring about approximation of the laws of the
Member States, it ought to have substantiated that assertion and the Arbitragehof ought to have made a note to that effect
in its decision to refer.

20     It should be borne in mind that the information provided in orders for reference must not only be such as to enable the Court
to reply usefully but must also enable the governments of the Member States and other interested parties to submit observations
pursuant to Article 23 of the Statute of the Court of Justice (order in Case C‐422/98 *Colonia Versicherung and Others* [1999] ECR I‐1279, paragraph 5).

21     In the case in the main proceedings, the decision making the reference contains sufficient information to address those requirements.
As indicated in paragraph 11 of this judgment, it appears from the decision making the reference that Advocaten voor de Wereld
is submitting that the subject-matter of the European arrest warrant ought to have been implemented by way of a convention
and not by way of a framework decision on the ground that, under Article 34(2)(b) EU, framework decisions may be adopted only
‘for the purpose of approximation of the laws and regulations of the Member States’, which is not the position in the present
case.

22     Information of this kind is sufficient not only to enable the Court to provide a useful reply but also to safeguard the possibility
open to the parties to the dispute, the Member States, the Council and Commission to submit observations pursuant to Article
23 of the Statute of the Court of Justice, as is, moreover, indicated by the observations lodged by all of the parties which
have intervened in these proceedings, including those submitted by the Czech Government.

23     The first question referred is therefore admissible.

 Substance

24     Advocaten voor de Wereld submits, in contrast to all of the other parties which have submitted observations in these proceedings,
that the subject-matter of the European arrest warrant ought, in accordance with Article 34(2)(d) EU, to have been regulated
by way of a convention.

25     In the first place, it argues, the framework decision could not have been validly adopted for the purpose of the approximation
of laws and regulations as referred to in Article 34(2)(b) EU, inasmuch as the Council is empowered to adopt framework decisions
only to approximate progressively the rules on criminal matters in the cases referred to in the third indent of the second
paragraph of Article 29 EU and in Article 31(e) EU. For other common action on judicial cooperation in criminal matters, the
Council must have recourse to conventions, pursuant to Article 34(2)(d) EU.

26     Second, pursuant to Article 31 of the Framework Agreement, the latter was to replace, as from 1 January 2004, the convention
law in the field of extradition in relations between Member States. Only a measure of the same kind, that is to say, a convention
within the meaning of Article 34(2)(d) EU, can validly derogate from the convention law in force.

27     That argument cannot be accepted.

28     As is clear in particular from Article 1(1) and (2) of the Framework Decision and recitals (5), (6), (7) and (11) in its preamble,
the purpose of the Framework Decision is to replace the multilateral system of extradition between Member States with a system
of surrender, as between judicial authorities, of convicted persons or suspects for the purpose of enforcing judgments or
of criminal proceedings based on the principle of mutual recognition.

29     The mutual recognition of the arrest warrants issued in the different Member States in accordance with the law of the issuing
State concerned requires the approximation of the laws and regulations of the Member States with regard to judicial cooperation
in criminal matters and, more specifically, of the rules relating to the conditions, procedures and effects of surrender as
between national authorities.

30     That is precisely the purpose of the Framework Decision in regard, inter alia, to the rules relating to the categories of
listed offences in respect of which there is no verification of double criminality (Article 2(2)), to the grounds for mandatory
or optional non-execution of the European arrest warrant (Articles 3 and 4), to the content and form of that warrant (Article
8), to the transmission of such a warrant and the detailed procedures governing such transmission (Articles 9 and 10), to
the minimum guarantees which must be granted to a requested or arrested person (Articles 11 to 14), to the time-limits and
procedures for the decision to execute that warrant (Article 17) and to the time-limits for surrender of the person sought
(Article 23).

31     The Framework Decision is based on Article 31(1)(a) and (b) EU, which provides that common action on judicial cooperation
in criminal matters is, respectively, to facilitate and accelerate judicial cooperation in relation to proceedings and the
enforcement of decisions and to facilitate extradition between Member States.

32     Contrary to what Advocaten voor de Wereld contends, there is nothing to justify the conclusion that the approximation of the
laws and regulations of the Member States by the adoption of framework decisions under Article 34(2)(b) EU is directed only
at the Member States’ rules of criminal law mentioned in Article 31(1)(e) EU, that is to say, those rules which relate to
the constituent elements of criminal offences and the penalties applicable within the areas listed in the latter provision.

33     Under the fourth indent of the first paragraph of Article 2 EU, the development of an area of freedom, security and justice
features as one of the objectives of the Union and the first paragraph of Article 29 EU states that, in order to provide citizens
with a high level of safety within such an area, common action is to be developed among the Member States, inter alia in the
field of judicial cooperation in criminal matters. According to the second indent of the second paragraph of Article 29 EU,
‘closer cooperation between judicial and other competent authorities of the Member States ... in accordance with the provisions
of Articles 31 [EU] and 32 [EU]’ is to contribute to the achievement of that objective.

34     Article 31(1)(a) and (b) EU does not, however, contain any indication as to the legal instruments which are to be used for
this purpose.

35     Moreover, it is in general terms that Article 34(2) EU states that the Council ‘shall take measures and promote cooperation,
..., contributing to the pursuit of the objectives of the Union’ and, ‘[to] that end’, empowers the Council to adopt a variety
of different types of measures, set out in Article 34(2)(a) to (d) EU, which include framework decisions and conventions.

36     Furthermore, neither Article 34(2) EU nor any other provision of Title VI of the EU Treaty draws a distinction as to the type
of measures which may be adopted on the basis of the subject-matter to which the joint action in the field of criminal cooperation
relates.

37     Article 34(2) EU also does not establish any order of priority between the different instruments listed in that provision,
with the result that it cannot be ruled out that the Council may have a choice between several instruments in order to regulate
the same subject-matter, subject to the limits imposed by the nature of the instrument selected.

38     In those circumstances, in so far as it lists and defines, in general terms, the different types of legal instruments which
may be used in the ‘pursuit of the objectives of the Union’ set out in Title VI of the EU Treaty, Article 34(2) EU cannot
be construed as meaning that the approximation of the laws and regulations of the Member States by the adoption of a framework
decision under Article 34(2)(b) EU cannot relate to areas other than those mentioned in Article 31(1)(e) EU and, in particular,
the matter of the European arrest warrant.

39     The interpretation to the effect that the approximation of the laws and regulations of the Member States by means of the adoption
of framework decisions is not only authorised in the areas referred to in Article 31(1)(e) EU is corroborated by Article 31(1)(c)
EU, which states that common action must also be aimed at ‘ensuring compatibility in rules applicable in the Member States,
as may be necessary to improve such [judicial] cooperation [in criminal matters]’, without drawing any distinction between
the different types of measures which may be used for the purpose of approximating those rules.

40     In the present case, in so far as Article 34(2)(c) EU precludes the Council from using a decision to effect approximation
of the laws and regulations of the Member States and in so far as the legal instrument of the common position within the meaning
of Article 34(2)(a) EU must be limited to defining the Union’s approach to a particular matter, the question thus arises as
to whether, contrary to the argument put forward by Advocaten voor de Wereld, the Council was able validly to regulate the
matter of the European arrest warrant by way of a framework decision rather than by means of a convention pursuant to Article
34(2)(d) EU.

41     While it is true that the European arrest warrant could equally have been the subject of a convention, it is within the Council’s
discretion to give preference to the legal instrument of the framework decision in the case where, as here, the conditions
governing the adoption of such a measure are satisfied.

42     This conclusion is not invalidated by the fact that, in accordance with Article 31(1) of the Framework Decision, the latter
was to replace from 1 January 2004, only in relations between Member States, the corresponding provisions of the earlier conventions
on extradition set out in that provision. Any other interpretation unsupported by either Article 34(2) EU or by any other
provision of the EU Treaty would risk depriving of its essential effectiveness the Council’s recognised power to adopt framework
decisions in fields previously governed by international conventions.

43     It follows that the Framework Decision was not adopted in a manner contrary to Article 34(2)(b) EU.

*The second question*

44     Advocaten voor de Wereld contends, in contrast to all of the other parties which have submitted observations in these proceedings,
that, to the extent to which it dispenses with verification of the requirement of the double criminality of the offences mentioned
in it, Article 2(2) of the Framework Decision is contrary to the principle of equality and non-discrimination and to the principle
of legality in criminal matters.

45     It must be noted at the outset that, by virtue of Article 6 EU, the Union is founded on the principle of the rule of law and
it respects fundamental rights, as guaranteed by the European Convention for the Protection of Human Rights and Fundamental
Freedoms, signed in Rome on 4 November 1950, and as they result from the constitutional provisions common to the Member States,
as general principles of Community law. It follows that the institutions are subject to review of the conformity of their
acts with the Treaties and the general principles of law, just like the Member States when they implement the law of the Union
(see, inter alia, Case C-354/04 P *Gestoras Pro Amnistía and Others* v *Council* [2007] ECR I-0000, paragraph 51, and Case C‐355/04 P *Segi and Others* v *Council* [2007] ECR I-0000, paragraph 51).

46     It is common ground that those principles include the principle of the legality of criminal offences and penalties and the
principle of equality and non-discrimination, which are also reaffirmed respectively in Articles 49, 20 and 21 of the Charter
of Fundamental Rights of the European Union, proclaimed in Nice on 7 December 2000 (OJ 2000 C 364, p. 1).

47     It is accordingly a matter for the Court to examine the validity of the Framework Decision in the light of those principles.

 The principle of the legality of criminal offences and penalties

48     According to Advocaten voor de Wereld, the list of more than 30 offences in respect of which the traditional condition of
double criminality is henceforth abandoned if those offences are punishable in the issuing Member State by a custodial sentence
or detention order for a maximum period of at last three years is so vague and imprecise that it breaches, or at the very
least is capable of breaching, the principle of legality in criminal matters. The offences set out in that list are not accompanied
by their legal definition but constitute very vaguely defined categories of undesirable conduct. A person deprived of his
liberty on foot of a European arrest warrant without verification of double criminality does not benefit from the guarantee
that criminal legislation must satisfy conditions as to precision, clarity and predictability allowing each person to know,
at the time when an act is committed, whether that act does or does not constitute an offence, by contrast to those who are
deprived of their liberty otherwise than pursuant to a European arrest warrant.

49     The principle of the legality of criminal offences and penalties (*nullum crimen, nulla poena sine lege*), which is one of the general legal principles underlying the constitutional traditions common to the Member States, has
also been enshrined in various international treaties, in particular in Article 7(1) of the European Convention for the Protection
of Human Rights and Fundamental Freedoms (see in this regard, inter alia, Joined Cases C-74/95 and C-129/95 *X* [1996] ECR I‐6609, paragraph 25, and Joined Cases C-189/02 P, C-202/02 P, C-205/02 P to C-208/02 P and C‐213/02 P *Dansk Rørindustri and Others* v *Commission* [2005] ECR I‐5425, paragraphs 215 to 219).

50     This principle implies that legislation must define clearly offences and the penalties which they attract. That condition
is met in the case where the individual concerned is in a position, on the basis of the wording of the relevant provision
and with the help of the interpretative assistance given by the courts, to know which acts or omissions will make him criminally
liable (see, inter alia, European Court of Human Rights judgment of 22 June 2000 in *Coëme and Others* v *Belgium*, Reports 2000-VII, § 145).

51     In accordance with Article 2(2) of the Framework Decision, the offences listed in that provision give rise to surrender pursuant
to a European arrest warrant, without verification of the double criminality of the act, ‘if they are punishable in the issuing
Member State by a custodial sentence or a detention order for a maximum period of at least three years and as they are defined
by the law of the issuing Member State’.

52     Consequently, even if the Member States reproduce word-for-word the list of the categories of offences set out in Article
2(2) of the Framework Decision for the purposes of its implementation, the actual definition of those offences and the penalties
applicable are those which follow from the law of ‘the issuing Member State’. The Framework Decision does not seek to harmonise
the criminal offences in question in respect of their constituent elements or of the penalties which they attract.

53     Accordingly, while Article 2(2) of the Framework Decision dispenses with verification of double criminality for the categories
of offences mentioned therein, the definition of those offences and of the penalties applicable continue to be matters determined
by the law of the issuing Member State, which, as is, moreover, stated in Article 1(3) of the Framework Decision, must respect
fundamental rights and fundamental legal principles as enshrined in Article 6 EU, and, consequently, the principle of the
legality of criminal offences and penalties.

54     It follows that, in so far as it dispenses with verification of the requirement of double criminality in respect of the offences
listed in that provision, Article 2(2) of the Framework Decision is not invalid on the ground that it infringes the principle
of the legality of criminal offences and penalties.

 The principle of equality and non-discrimination

55     According to Advocaten voor de Wereld, the principle of equality and non-discrimination is infringed by the Framework Decision
inasmuch as, for offences other than those covered by Article 2(2) thereof, surrender may be made subject to the condition
that the facts in respect of which the European arrest warrant was issued constitute an offence under the law of the Member
State of execution. That distinction, it argues, is not objectively justified. The removal of verification of double criminality
is all the more open to question as no detailed definition of the facts in respect of which surrender is requested features
in the Framework Decision. The system established by the latter gives rise to an unjustified difference in treatment as between
individuals depending on whether the facts alleged to constitute the offence occurred in the Member State of execution or
outside that State. Those individuals will thus be judged differently with regard to the deprivation of their liberty without
any justification for that difference.

56     The principle of equality and non-discrimination requires that comparable situations must not be treated differently and that
different situations must not be treated in the same way unless such treatment is objectively justified (see, in particular,
Case C-248/04 *Koninklijke Coöperatie Cosun* [2006] ECR I‐0000, paragraph 72 and the case-law there cited).

57     With regard, first, to the choice of the 32 categories of offences listed in Article 2(2) of the Framework Decision, the Council
was able to form the view, on the basis of the principle of mutual recognition and in the light of the high degree of trust
and solidarity between the Member States, that, whether by reason of their inherent nature or by reason of the punishment
incurred of a maximum of at least three years, the categories of offences in question feature among those the seriousness
of which in terms of adversely affecting public order and public safety justifies dispensing with the verification of double
criminality.

58     Consequently, even if one were to assume that the situation of persons suspected of having committed offences featuring on
the list set out in Article 2(2) of the Framework Decision or convicted of having committed such offences is comparable to
the situation of persons suspected of having committed, or convicted of having committed, offences other than those listed
in that provision, the distinction is, in any event, objectively justified.

59     With regard, second, to the fact that the lack of precision in the definition of the categories of offences in question risks
giving rise to disparate implementation of the Framework Decision within the various national legal orders, suffice it to
point out that it is not the objective of the Framework Decision to harmonise the substantive criminal law of the Member States
and that nothing in Title VI of the EU Treaty, Articles 34 and 31 of which were indicated as forming the legal basis of the
Framework Decision, makes the application of the European arrest warrant conditional on harmonisation of the criminal laws
of the Member States within the area of the offences in question (see by way of analogy, inter alia, Joined Cases C-187/01
and C-385/01 *Gözütok and Brügge* [2003] ECR I-1345, paragraph 32, and Case C‐467/04 *Gasparini and Others* [2006] ECR I‐0000, paragraph 29).

60     It follows that, in so far as it dispenses with verification of double criminality in respect of the offences listed therein,
Article 2(2) of the Framework Decision is not invalid inasmuch as it does not breach Article 6(2) EU or, more specifically,
the principle of legality of criminal offences and penalties and the principle of equality and non-discrimination.

61     In the light of all of the foregoing, the answer must be that examination of the questions submitted has revealed no factor
capable of affecting the validity of the Framework Decision.

**Costs**

62     Since these proceedings are, for the parties to the main proceedings, a step in the action pending before the national court,
the decision on costs is a matter for that court. Costs incurred in submitting observations to the Court, other than the costs
of those parties, are not recoverable.

On those grounds, the Court (Grand Chamber) hereby rules:

**Examination of the questions submitted has revealed no factor capable of affecting the validity of Council Framework Decision
2002/584/JHA of 13 June 2002 on the European arrest warrant and the surrender procedures between Member States.**
