B Explanatory memorandum
by Mr Vladimir Vardanyan, rapporteur
1 Introduction
1. The European Convention on
Mutual Assistance in Criminal Matters (ETS No. 30, “the Convention”)
was opened for signature in 1959 and entered into force in 1962
(). The Convention aimed to enhance co-operation between member
States in criminal investigations, evidence gathering, and the prosecution
of suspects. At the time of its adoption, a significant part of
the Convention focused on the means of co-operation available at
the time, notably the use of letters rogatory to request procuring
and transferring evidence.
2. Two additional protocols have since updated the Convention.
The first of these was opened for signature in 1978 (ETS No. 99).
This removed the option provided by the Convention to deny assistance
solely on the basis that the request pertains to an offense deemed
a fiscal matter by the requested Party. It broadened international
co-operation to include the service of documents related to the
enforcement of sentences and similar measures. Additionally, it
introduced provisions for the exchange of information regarding
judicial records. The second protocol was opened for signature in 2001
(ETS No. 182). It was intended to improve responses to cross-border
crime in light of social, political, and technological developments,
notably by broadening the range of situations in which mutual assistance
may be requested and making the provision of assistance easier,
quicker, and more flexible.
3. The Committee of Experts on the Operation of European Conventions
on Co-operation in Criminal Matters (PC-OC), operating under the
authority of the European Committee on Crime Problems (CDPC), is tasked
with reviewing the functioning and implementation of Council of
Europe conventions and agreements related to international co-operation
in criminal matters, with a view to adapting them and enhancing
their practical application as needed.
4. In carrying out its responsibilities, the PC-OC recognised
the necessity to update several provisions of the Convention and
its Second Additional Protocol, to address recent advancements in
practices and support systems for mutual assistance, such as the
increased use of video-conferencing and other technological tools. Additionally,
it identified areas where practitioners have noted gaps that could
be addressed.
5. After considering various approaches, the PC-OC determined
that introducing an additional protocol to the Convention would
be the most effective and practical solution to modernise it in
line with these developments. This proposal received approval from
the CDPC, leading to the inclusion of the preparation of a new protocol
in the PC-OC's terms of reference for 2022–2025 by the Committee
of Ministers.
6. Based on proposals from various delegations, the PC-OC drafted
a third additional protocol to the Convention (“the draft third
protocol”). This draft was finalised during its 86th meeting (12–14 November 2024) and
subsequently submitted to the CDPC for approval. The CDPC reviewed
and approved the draft third protocol during its 86th plenary session
(20–22 November 2024), forwarding it to the Committee of Ministers for
further consideration.
7. On 19 March 2025, at their 1523rd meeting, the Ministers’
Deputies agreed to transmit the draft third protocol to the Parliamentary
Assembly for opinion. The Committee on Legal Affairs and Human Rights appointed
me as rapporteur at its meeting on 7 April 2025.
8. In this explanatory memorandum, I will summarise the previous
work of the Assembly on mutual assistance in criminal matters (section 2)
and set out the key aspects of the draft third protocol (section 3).
I will briefly address the lack of public commentary on the text
(section 4), before exploring the issue of State surveillance (section 5).
Finally, I will set out some conclusions (section 6).
2 Previous and current work of the Assembly
on mutual assistance in criminal matters
9. The Assembly has previously
issued Opinions on the original Convention (
Opinion 30 (1959)) and on the Second Additional Protocol to the
Convention (
Opinion 231
(2001)).
3 Main
features of the draft third protocol
11. The draft third protocol aims
to enhance the capacity of member States and partner States to effectively combat
crime. It seeks to achieve this goal by updating and expanding the
Convention, along with its two existing Additional Protocols. This
purpose is achieved through modernising the current provisions that
govern mutual assistance, broadening the scope of means via which
mutual assistance can be requested, facilitating assistance and
by making it faster and more flexible. By implementing these improvements,
the aim of the draft third protocol is to create a more robust framework
for international co-operation in criminal matters, enabling States
to address contemporary challenges in law enforcement more effectively.
12. The main features of the draft third protocol are as follows:
- article 1 addresses the channels
of communication to be used for mutual assistance requests. This article
amends Article 15 of the Convention, identifying secure means of
electronic communication as the preferred method. The provision
further specifies the range of competent authorities which can make particular
requests, depending on the subject matter;
- article 2 concerns the use of video conferencing. This
article reflects the development of practices which emerged during
the covid-19 pandemic. It provides that Parties to the Convention
may request that hearings take place by video-conference, in accordance
with a set procedure. The requested Party shall agree to such a
hearing, provided that the use of the video conference is not contrary
to the fundamental principles of its law and that it has the technical
means to carry it out. A list of rules is set out, establishing relevant
safeguards. Parties may at their discretion facilitate video conferences
involving the accused person or the suspect, but only with the agreement
of the competent judicial authorities and the individual concerned,
in accordance with national law and relevant international instruments.
In this context, it is worth noting that the case law of the European
Court of Human Rights (“the Court”) on hearings via video link establishes
that a defendant’s participation in proceedings by video-conference
is not as such contrary to the European Convention on Human Rights
(ETS No. 5), but that recourse to this measure in any given case
must serve a legitimate aim, and that the arrangements for the giving
of evidence must be compatible with the requirements of respect
for due process, as laid down in Article 6 of the Convention.Note The Court has held
that the defendant must be able to follow the proceedings and to
be heard without technical impediments and have effective and confidential
communication with a lawyer.Note I
believe that these safeguards for the accused or suspect should
be explicitly mentioned in the draft explanatory report in relation
to Article 2, paragraph 8;
- article 3 establishes a framework for the use of technical
recording devices that record positions, sound, or images in the
territory of another Party. This covers, for example, when the subject
of an investigation has a GPS tracker on their vehicle, when an
audio recording device has been put in place, or software has been
installed on portable electronic devices. When the device is taken
to a different jurisdiction, it is beneficial for law enforcement
agencies to be able to continue to use the data collected by the
device. The article provides that, whenever possible, requests to
carry out such surveillance on the territory of another Party should
be made in advance. Such requests should provide a set list of information, including
the authorising authority of the surveillance, as well as its legal
basis, necessity, subject details, implementing measures, and expected
duration. Requests may be refused on the grounds that the recording
would not have been allowed in a similar domestic case according
to the law of the requested Party. The draft explanatory report
stipulates that such a refusal may be based on human rights concerns
assessed according to the law of the requested Party, in particular
as regards the right to respect for private and family life or protection
against discrimination on any prohibited ground. Requests may also
be refused on the grounds set out in Articles 2 and 5 of the Convention.
These grounds include cases where the request concerns an offence
which the requested Party considers a political offence, or an offence
connected with a political offence; or where the requested Party
considers that execution of the request is likely to prejudice the
sovereignty, security, public order or other essential interests
of its country;
- article 3 also provides for urgent situations where it
is not possible to make a request in advance of a technical recording
device entering another country. In such cases, the Party using
the device shall immediately notify the other Party, providing the
same information that is required to make a request in advance.
The device may remain active pending authorisation of the notified
Party. That notified Party shall, as soon as possible and within
ninety-six hours at the latest, indicate whether the device may remain
active or whether it validates past activity. In cases where a recording
would not have been allowed in a similar domestic case according
to the law of the requested Party, the notified Party may decide
that the recording may not be carried out or shall be terminated.
The procedure also provides the notified Party with a wide range
of controls of the activity, including: that any material already
recorded while the subject was on its territory may not be used,
or that it may be used only under certain conditions; that the continuation
or validation of the recording is dependent on the submission of
a formal request for mutual assistance; or that the data recorded
on its territory should be partially or fully destroyed. The notifying
Party may not use the recordings as evidence in criminal proceedings,
without explicit authorisation of the notified Party;
- article 3 also provides options for Parties to declare
that they will apply certain restrictions to the notification procedure.
Such restrictions may include a prohibition on data collection in
private homes and places not accessible to the public; and/or limiting
authorisation to investigations concerning certain criminal offences;
- article 4 sets out a framework for Parties to request
that another Party intercepts telecommunications in the context
of criminal investigations. The article requires such requests to
include specific information, including a precise description of
the telecommunication to be intercepted, relevant technical data, justification
for the necessity of the measure, confirmation of authorisation
by the requesting Party’s competent authority, and the intended
duration of the interception. The requested Party may refuse execution,
on the same grounds that it may refuse requests made under Article 3.
The requested Party may also impose conditions on the execution
of requests, such as requiring destruction of irrelevant recorded
data, notifying the intercepted individual after the measure, limiting
the use of the evidence to the purposes specified in the request,
or imposing any other conditions applicable in a similar domestic case.
The requesting Party may also ask for transcription, decoding, or
decrypting of recordings if necessary, subject to agreement by the
requested Party. Judicial authorities in the requested Party may destroy
parts of the records deemed irrelevant or covered by legal privilege
before transmitting them to the requesting Party. If the intercepted
communication reveals that an offence was committed wholly or mainly
within the territory of the requested Party, the requesting Party
is encouraged to consider transferring information to enable prosecution
in that jurisdiction;
- article 5 of the draft third protocol sets out rules as
to the payment of costs involved in the provision of mutual assistance.
It sets out a list of particular costs that will be refunded by
the requesting Party, unless the Parties agree otherwise. Other
than this, the article provides that Parties shall not claim from
each other the refund of any costs resulting from the application
of the Convention or its Protocols, except for costs incurred by
attendance of experts in the territory of the requested Party; costs
incurred by the transfer of a person in custody; and costs of a
substantial or extraordinary nature. Article 5 is exactly the same
as a similar provision in the Second Protocol to the Convention,
except for one change. The list of particular costs that will be
refunded by the requesting Party has been expanded, to include “the
costs which are incurred by telecommunications operators or service
providers in executing requests for the interception of telecommunications,
as well as the costs arising from the transcription, decoding and decrypting
of the intercepted communications when applicable”;
- article 6 addresses the issue of timely execution of mutual
assistance requests in criminal matters. It establishes a general
principle that such requests should be handled with the same celerity
and priority as comparable domestic cases. The article recognises
that certain circumstances, such as procedural deadlines, the gravity
of the offence, or other urgent matters, may necessitate setting
specific time limits for execution. In such cases, the requested
Party should make every effort to meet these deadlines, to the extent
that this is possible. When the requested Party cannot meet a specified
time limit, it must promptly inform the requesting Party through
any available means, after which the Parties may consult on appropriate
timing and conditions;
- article 7 addresses data protection, replacing Article 26
of the Second Additional Protocol. It provides that personal data
transferred as a result of the execution of a request made under
the Convention or its Protocols may only be used by the receiving
Party for the purpose of proceedings to which the Convention or
any of its Protocols apply; for judicial or administrative proceedings
which are directly linked; or for preventing an immediate and serious
threat to public security. Data may be used for other purposes,
if prior consent is provided by either the transferring Party or
the data subject. Parties may refuse to transfer personal data obtained
as a result of the execution of a request made under the Convention
or its Protocols where such data are protected under their national
legislation, and/or when the receiving Party is not bound by the
Convention for the Protection of Individuals with regard to Automatic
Processing of Personal Data (ETS No. 108), as modernised by the
Protocol amending this Convention (CETS No. 223), unless the receiving
Party undertakes to afford such protection to the data as is required
by the transferring Party. Any Party that transfers personal data
obtained as a result of a request made under the Convention or its
Protocols may require the receiving Party to provide information
of the use made of the data. Finally, any Party may, by a declaration,
require that, within the framework of procedures for which it could
have refused or limited the transmission or the use of personal
data in accordance with the provisions of the Convention or one
of its Protocols, personal data which it transmits to another Party
not be used by the latter unless with its previous consent;
- the remaining articles of the draft third protocol provide
for: the friendly settlement of difficulties regarding the interpretation
of the Convention and its protocols (Article 8); a summary of how
the provisions of the draft third protocol relate to existing provisions
in the Convention and its Additional Protocols (Article 9); principles
governing the Parties’ signature of the Protocol and its entry into
force (Article 10); accession to the Protocol (Article 11); its
territorial application (Article 12); reservations and declarations (Article 13);
denunciation (Article 14); and notifications (Article 15). Articles 10
to 15 are based on the “Model final clauses for Conventions, Additional
Protocols and Amending Protocols concluded within the Council of
Europe” adopted by the Committee of Ministers on 5 July 2017, and
the final clauses of the Convention;
- article 13 provides that the only reservations possible
in relation to the draft third protocol are for Article 3 and 4.
Parties may avail themselves of the right not to accept either one
or both of these articles, either wholly or in part.
4 Positions
voiced by different stakeholders
13. There were no representatives
of legal associations or other non-governmental organisations present
in any of the PC-OC meetings during which the draft third protocol
was prepared. It is noteworthy that no civil society organisations
attended the drafting process of the draft third protocol – and
there has been no public commentary about the text. In this context,
there is a shortage of information and analysis about the important questions
reflected in the draft protocol including issues surrounding the
use of State surveillance.
5 The
issue of State surveillance
14. The draft third protocol impacts
an issue affecting fundamental rights that the Assembly has been particularly
concerned with in recent years: the use of spyware and other means
of State surveillance.
5.1 Judgments
of the European Court of Human Rights
15. The European Court of Human
Rights has issued many judgments on the wider issue of State surveillance,
identifying practices which are incompatible with Article 8 of the
European Convention on Human Rights. Most concerningly, many of
these judgments are still pending implementation, meaning that the Committee
of Ministers of the Council of Europe has not yet been provided
with sufficient evidence to demonstrate that the problem(s) which
caused the human rights violation(s) has been resolved. Judgments
still pending implementation include those identifying a lack of
sufficient safeguards against abuse in the use of secret surveillance
(
Ekimdzhiev and Others v. Bulgaria,
Note Zoltan Varga v. Slovakia,
Note Bucur
and Toma v. Romania,
NoteIordachi
and Others v. the Republic of Moldova,Note and
Pietrzak and Bychawska-Siniarska and Others
v. PolandNote),
inadequate reasoning in the decisions of domestic courts authorising
surveillance measures (
Simic v. Serbia,Note Potoczka and Adamco v. SlovakiaNote), the impossibility
of third parties in criminal proceedings to challenge telephone
tapping warrants (
Contrada v. Italy (No.4),Note Pruteanu
v. RomaniaNote),
and the unjustified interception of lawyers’ telephone data (
Bersheda and Rybolovlev v. MonacoNote).
5.2 Spyware
– findings and work of Council of Europe bodies
16. The European Court of Human
Rights has not yet issued judgments on the use of spyware. However, this
has been a subject of great concern to the Assembly and the European
Commission for Democracy through Law (Venice Commission).
17. In
Resolution 2513 (2023) “Pegasus and similar spyware and secret State surveillance”,
the Assembly noted how investigative reports had concluded that
many Council of Europe member States have acquired and used Pegasus
for targeted surveillance. Others have acquired or used similar
spyware, such as Candiru and Predator. Spyware can be extremely
intrusive, granting the user complete and unrestricted access to
all sensors and information on the targeted device. It turns the
smartphone into a 24-hour surveillance device, accessing the camera
and microphone, geolocation data, e-mails, messages, photos, videos,
passwords and applications. The Assembly expressed deep concern
that spyware have been used illegally or for illegitimate purposes
by several member States, including against journalists, political
opponents, and human rights defenders. Secret surveillance of political
opponents, public officials, journalists, human rights defenders
and civil society actors for purposes other than those exhaustively
enumerated in Article 8.2 of the European Convention on Human Rights
amounts to a clear violation of the right to respect for private
life (Article 8).
18. The Assembly concluded that the use of such spyware should
be limited to exceptional situations, as a measure of last resort,
to prevent or investigate a specific act amounting to a genuine
and serious threat to national security or a specific and precisely
defined serious crime, targeting only the person suspected of committing
or planning to commit those acts, and always under court supervision.
In order to limit such a high level of intrusiveness, States should
take into account the proportionality of new spyware before acquiring
and using it; they should also consider using spyware without some
of the most invasive features of Pegasus or a version that is programmed
in such a way that it limits access to what is strictly necessary.
19. The Assembly called on member States which seem to have acquired
or used Pegasus, including Germany, Belgium, Luxembourg and the
Netherlands, to clarify the framework of its use and applicable oversight
mechanisms. It invited them to send this information, as well as
any statistics on the use of Pegasus, to the Assembly and the Venice
Commission within three months. The Assembly also asked the Venice Commission
to assess the legislative framework and practice on targeted surveillance
of all member States, in order to assess if the framework contains
adequate and effective guarantees against any possible abuse of spyware.
20. In
Recommendation 2258 (2023), the Assembly called on the Committee of Ministers to
adopt a recommendation to member States of the Council of Europe
on secret surveillance and human rights, particularly in the light
of the threats posed by new surveillance technologies and spyware;
to examine the feasibility of a Council of Europe convention on
the acquisition, use, sale and export of spyware; and to co-ordinate
its efforts with other international organisations for the purposes
of standard setting and co-operation. In its reply to the Assembly’s
recommendation of 4 September 2024 (
Doc. 16030), the Committee of Ministers indicated that a recommendation
on secret surveillance and human rights would be feasible and have
genuine added value – and invited the Steering Committee for Human
Rights (CDDH) to bear this in mind for the mid-term review of its
terms of reference. In November 2024, the CDDH decided to request
the Committee of Ministers to give it terms of reference to prepare
a non-binding instrument on human rights, the use of spyware, and
secret State surveillance.
Note
21. The Venice Commission adopted a report in December 2024, entitled
“A rule of law and human rights compliant regulation of spyware”,
at the request of the Assembly. This concluded that spyware is “an unprecedently
intrusive surveillance tool” and that it is “crucial to provide
for clear contours concerning the use of spyware by State in order
to prevent and eradicate abusive practices”. The Venice Commission
found that the development and use of spyware should only be possible
if the relevant legal framework meets certain requirements, setting
out an 11-point list of minimum safeguards which includes the following.
The use of spyware must be regulated by primary legislation, which
should clearly define the (restricted) scope
ratione materiae,
personae and
temporis of
targeted surveillance through spyware. The requesting authorities
(law enforcement or intelligence agency) should always demonstrate
that the information sought in the investigation was necessary to
the legitimate purpose and could not be obtained by less intrusive
means. There must be well-regulated
ex-ante authorisation
procedures before a court or another independent body; and the duration of
the surveillance measures must be limited to what is strictly necessary.
The whole surveillance process needs to be backed up by effective
external independent oversight institutions, which are sufficiently resourced,
qualified and specialised, and cannot be entrusted exclusively to
the executive. The persons under surveillance must be notified subsequently,
subject to exceptions defined by law, so that they can be involved in
monitoring and challenging the measure.
Note
22. Although the Venice Commission did not make an individual
assessment of whether the legislative framework of each member State
complies with all minimum safeguards, it transpires from the report
that many member States do not yet have all these safeguards in
place. In fact, relatively few States have developed legislation
specifically regulating the use of spyware. The Assembly will remain
seized of this important matter, including through the follow-up
work of Pieter Omtzigt (Netherlands, EPP/CD), rapporteur for follow-up
to Resolution 2513 (2023) “Pegasus and similar spyware and secret
State surveillance”, for the Committee on Legal Affairs and Human
Rights.
5.3 State
surveillance – contents of the draft third protocol
23. Many of the key provisions
of the draft third protocol have the effect of establishing new
procedures for Parties to co-operate to carry out electronic surveillance.
Article 3 establishes a procedure to facilitate continued surveillance
where one Party has initiated electronic surveillance of a subject
and that subject moves to the territory of another Party. Article 4
establishes a procedure where one Party can request that another intercepts
the telecommunications of a subject. Article 5 establishes that
the costs of intercepting telecommunications will be reimbursed
by the Party that requested the interception.
24. Spyware is not mentioned explicitly in any of these provisions,
but according to the draft explanatory report, Article 3 is meant
to cover the continued use of software installed on portable electronic
devices in the territory of another Party. Spyware would clearly
fall within the scope of this provision.
25. It is very important that law enforcement agencies are able
to carry out surveillance in cross-border situations – as long as
this is done only in appropriate cases and with proper safeguards.
26. There are some reasons to conclude that the draft third protocol
increases the procedural guarantees governing electronic surveillance.
This is because, mutual legal assistance requests for cross-border
electronic surveillance are already possible under the existing
Convention and its protocols. The provisions of the draft third
protocol establish procedures that are specifically tailored to
the use of electronic surveillance and that provide for additional
safeguards. In particular, Article 3 (on the use of technical recording
devices in the territory of another Party) and Article 4 (on requests
for interception of telecommunications) have particular safeguarding
features. The first is that Parties to the Protocol may choose not
to accept either of these Articles, either wholly or in part. The
second is that, in relation to Article 3, Parties may declare that
the notification procedure cannot be used for the collection of
data in private homes and places; and/or that the notification procedure
can only be used for a limited list of offences.
Note Third, under both Article 3 and
Article 4, the requesting States need to justify that the measures
were ordered lawfully and why the purpose sought with the use of
the technical recording device or the interception of telecommunications
cannot be adequately achieved by less intrusive measures, i.e. that
surveillance is used as a measure of last resort. Fourth, both Article 3
and Article 4 establish a safeguard which is not present in relation
to other subjects of mutual legal assistance requests in most cases,
which is that Parties may choose to refuse a request when the same
request would not have been accepted in a similar domestic case
according to the law of the notified Party.
27. In this way, there are indications that the draft third protocol
introduces a greater range of reasons for a Party to refuse to allow
electronic surveillance in its territory: either because it has
declared that it will not accept mutual assistance requests in such
cases; or by deciding that such a request should be refused, through
the application of its own domestic law to the circumstances of
the case (including on grounds that it is incompatible with human
rights standards), which is not possible for other subjects of mutual
assistance requests.
28. It is also important to note that the draft third protocol
will have no impact on the actions of States conducting clandestine
or intelligence operations. It will only be relied upon by States
when they are engaged in a criminal procedure. Therefore, by establishing
an additional procedure for technological surveillance, which has
additional safeguards that were not present before, the draft third
protocol may expose such surveillance to additional examination.
29. At the same time, the very adoption of the draft third protocol
also raises some concerns – not because of the provisions of the
draft third protocol itself, but because of the general context
of the regulation of State surveillance in Europe. As set out above,
there are widespread and significant shortcomings in the regulation of
State surveillance as a whole (as indicated by judgments of the
European Court of Human Rights which are still pending implementation),
and the use of spyware in particular (as indicated by reports of
the Assembly and opinions of the Venice Commission). The draft third
protocol formalises a legal procedure for the use of State surveillance
in cross-border contexts. Council of Europe member States are therefore
institutionalising co-operation for State surveillance, at a time
when most States have demonstrably inadequate regulation of it. This
should serve as a timely reminder of the need for States to redouble
their efforts to ensure there are adequate safeguards for the use
of State surveillance – not only in their own countries, but also
in the countries that they are co-operating with in criminal matters.
6 Conclusions
30. The constant movement of individuals
across borders, as well as the transnational nature of criminal activities
and organisations, means that States cannot fight crime effectively
without co-operating with each other. It is essential that this
co-operation is as efficient and effective as possible, whilst retaining
the necessary safeguards to protect fundamental rights. The Convention
was first created in 1959 and has been updated with additional Protocols
roughly every two decades: firstly in 1978, secondly in 2001, and
thirdly now in 2025. The Assembly should welcome this work to modernise
the Convention to reflect the use of modern technology.
31. The draft third protocol does this by identifying secure electronic
communications as the preferred way of transmitting mutual assistance
requests in criminal matters; formalising and facilitating the use
of video conferencing for hearings; establishing frameworks for
the use of electronic recording devices in the territory of other
States; and formalising a system by which one Party can request
another to intercept electronic communications in its territory.
These are all welcome and important steps to ensuring timely and
effective co-operation in criminal matters.
32. The draft third protocol provides an improved legal basis
for international co-operation to facilitate State surveillance,
with relevant safeguards. At the same time, given a context where
there is inadequate regulation of State surveillance in many European
States – particularly for spyware – the adoption of the draft third protocol
should be a wake-up call for the need for new efforts by States
to ensure better regulation of State surveillance.
33. In light of these concerns, I suggest that the Assembly welcomes
the draft third protocol, whilst emphasising that it must be accompanied
by renewed efforts to ensure that State surveillance is carried
out in an appropriate manner. This includes the full and timely
implementation of judgments of the European Court of Human Rights,
the adoption of legal frameworks for the development and use of
spyware that include the minimum safeguards set out by the Venice
Commission, the adoption of a recommendation on secret surveillance
and human rights, and the elaboration of a legally binding Council
of Europe instrument on the acquisition, use, sale and export of
spyware.
