International Criminal Law – How Do States Cooperate with the Special Court for Sierra Leone, and What Are the Legal Limits of That Cooperation?
​
I. Co-operation with the Special Court for Sierra Leone
1. Sierra Leone’s Duty to Cooperate Fully with the Court
Under Article 17(1) of the SCSL Agreement (Special Court for Sierra Leone Agreement), the Republic of Sierra Leone undertook a broad and binding obligation to “cooperate with all organs of the Special Court at all stages of the proceedings.”
In practical terms, this meant that Sierra Leone had to:

• Allow the Office of the Prosecutor access to:
  • Relevant sites (crime scenes, detention facilities, archives, etc.),
  • Persons (suspects, witnesses, officials),
  • Documents and records necessary for investigations.
• Facilitate investigative activities inside its territory.

Article 17(2) of the SCSL Agreement further specified that Sierra Leone must:

• “Comply without undue delay” with any:
  • Request for assistance issued by the Special Court for Sierra Leone (SCSL), or
  • Order made by the Chambers of the Court.

The kinds of assistance explicitly mentioned included (but were not limited to):

• Identifying and locating persons relevant to investigations and trials,
• Serving documents, such as summonses or subpoenas,
• Arresting or detaining persons wanted by the Court,
• Transferring indicted persons (indictees) to the custody of the SCSL.

In other words, Sierra Leone assumed a comprehensive obligation of judicial and law-enforcement cooperation with the Court.
The same cooperation regime was essentially copied over--mutatis mutandis (with necessary adaptations)—into Article 11 of the RSCSL Agreement (Residual Special Court for Sierra Leone Agreement), governing cooperation with the Residual Special Court for Sierra Leone (RSCSL), which handles the Court’s ongoing residual functions (e.g., witness protection, enforcement of sentences).


2. The Position of Third States: No General Legal Duty to Cooperate
In sharp contrast to Sierra Leone’s legally binding duty—and also in contrast to the position that existed under the Statutes of the ICTY (International Criminal Tribunal for the former Yugoslavia) and the ICTR (International Criminal Tribunal for Rwanda)--third states (i.e., all states other than Sierra Leone) had no general international legal obligation to cooperate with the SCSL.
As the United Nations Secretary-General clearly explained, the Special Court for Sierra Leone:

• “Lacked the power to request the surrender of an accused from any third State and to induce the compliance of its authorities with any such request.”

In other words:

• The SCSL had no enforcement or compulsory powers over third states.
• If a suspect was located outside Sierra Leone in a third state, the Court had no legal authority to require that state to:
  • Arrest the person, or
  • Surrender them to the Court.

The Secretary-General further suggested that, if the United Nations Security Council wished to strengthen the Court’s deterrent effect, it might:

• Consider granting the SCSL specific Chapter VII powers (under the United Nations Charter) for the limited purpose of requesting the surrender of suspects located outside Sierra Leone’s jurisdiction, and compelling compliance with such requests.

However, the UN Security Council never took this step. The SCSL thus remained a treaty-based hybrid court, without the Chapter VII “teeth” that the ICTY and ICTR possessed (those tribunals were created directly by Security Council resolutions under Chapter VII and had binding cooperation obligations on UN Member States).
Importantly, the fact that third states were not legally obliged to assist the SCSL did not prevent the Court from asking them for help. This point was made explicit in Rule 8(C) of the SCSL Rules of Procedure and Evidence (RPE). That rule allowed the Court to:

• Invite third states to provide assistance,
• Even though those states were under no legal duty to comply.

Thus, the framework created a distinction between:

• Sierra Leone – bound by a strict and detailed cooperation obligation, and
• Other states – free, but not required, to assist at the Court’s request.

II. Conclusion
Whether the Special Court for Sierra Leone (SCSL):

• Provided meaningful justice,
• Contributed positively to the consolidation of peace in Sierra Leone, and
• Delivered genuine vindication for victims

are deep evaluative questions better addressed in a broader political, social, and legal forum.
From an institutional and legal-design perspective, however, the SCSL can largely be regarded as a successful experiment in international criminal justice. It pioneered a “hybrid” model:

• An international criminal court created and empowered by a bilateral treaty between:
  • An international organization (the United Nations), and
  • A single state (Sierra Leone),
• Rather than solely by multilateral treaty among many states or solely by a Security Council resolution.

The key open question is whether this model—a hybrid court established through an agreement between a single state and an international organization—will be seen as attractive and feasible for future conflicts and contexts.
If similar courts are established in other countries or regions:

• The experience of the SCSL and the Residual Special Court for Sierra Leone (RSCSL) will be highly instructive, especially in:
  • Calibrating cooperation duties,
  • Balancing sovereignty and international involvement, and
  • Designing legacy and residual mechanisms.

III. Ten Case Scenarios with Solutions (Focused on Cooperation and the SCSL Model)
Below are 10 illustrative scenarios applying the cooperation framework and institutional lessons from the SCSL and RSCSL.


Case Scenario 1 – Refusal by Sierra Leone to Execute an Arrest Warrant
Facts:
The SCSL issues an arrest warrant for a former rebel commander living openly in Sierra Leone. The Sierra Leone police hesitate to arrest him due to political pressure.
Legal Issues:

• Does Sierra Leone have a legal obligation to arrest him?
• Can the SCSL compel domestic authorities?

Solution:

• Under Article 17(1) and 17(2) of the SCSL Agreement, Sierra Leone is obliged to:
  • Cooperate fully with all organs of the Court, and
  • “Comply without undue delay” with requests and orders, including those for arrest and transfer.
• Failure to arrest would amount to a breach of its treaty obligations.
• The Court could:
  • Formally record non-compliance,
  • Raise the issue with the United Nations and the international community,
  • Apply political and diplomatic pressure, even if it lacks its own enforcement arm.

Outcome:
Legally, Sierra Leone must execute the warrant; politically, enforcement depends on external and internal pressure.


Case Scenario 2 – Suspect in a Third State with No Legal Duty to Cooperate
Facts:
A suspect indicted by the SCSL flees to Country X, which is not a party to any agreement to cooperate with the SCSL.
Legal Issues:

• Is Country X obliged to arrest and surrender the suspect?
• What can the SCSL do?

Solution:

• Unlike Sierra Leone, Country X has no binding duty to cooperate.
• As the Secretary-General noted, the SCSL “lacks the power to request the surrender of an accused from any third State and to induce compliance.”
• However, under Rule 8(C) of the SCSL Rules of Procedure and Evidence, the Court may invite Country X to assist voluntarily.
• Country X may comply for reasons of:
  • Political goodwill,
  • Commitment to accountability,
  • Diplomatic incentives.

Outcome:
Surrender depends on voluntary cooperation by Country X; the Court cannot legally compel it.


Case Scenario 3 – Hypothetical Chapter VII Empowerment (Counterfactual)
Facts:
Imagine the United Nations Security Council had adopted a Chapter VII resolution compelling all UN Member States to cooperate with the SCSL, including arrest and surrender of suspects.
Legal Issues:

• How would this change cooperation duties?
• Would third states still have a choice?

Solution:

• Under such a Chapter VII decision, all UN Member States would be obliged to comply, similar to the regime under the ICTY and ICTR.
• Arrest and surrender requests would become binding obligations, enforceable under the UN Charter.
• Non-compliance could lead to:
  • Reports to the Security Council,
  • Sanctions or other Chapter VII measures.

Outcome:
This would transform the SCSL from a treaty-based hybrid court into a quasi-UN enforcement body, closing the cooperation gap with third states.


Case Scenario 4 – Request for Documents from a Ministry in Sierra Leone
Facts:
The SCSL Prosecutor requests access to military archives held by the Ministry of Defence of Sierra Leone, including war-time communications.
Legal Issues:

• Can Sierra Leone refuse on national security grounds?
• How far does Article 17 extend?

Solution:

• Article 17(1) requires Sierra Leone to ensure access to relevant documents for investigations.
• While national security concerns may be raised, they must be balanced against:
  • The seriousness of the alleged crimes, and
  • The Court’s mandate to combat impunity.
• The Court and the state may negotiate:
  • Protective measures (e.g., redactions, in camera hearings),
  • Limited disclosure to certain organs of the Court.

Outcome:
Sierra Leone remains under a strong cooperation duty, but the Court may accommodate legitimate security concerns through protective arrangements.


Case Scenario 5 – Service of Documents on a Witness Abroad
Facts:
The SCSL needs to serve a summons on a key witness residing in Country Y, which is not bound to cooperate.
Legal Issues:

• Can the Court directly compel Country Y to serve documents?
• What legal tools exist?

Solution:

• The SCSL cannot legally compel Country Y.
• Under Rule 8(C) of the SCSL Rules of Procedure and Evidence, the Court may:
  • Invite Country Y to assist in service of documents.
• If Country Y refuses, the SCSL may:
  • Use diplomatic channels,
  • Seek cooperation through mutual legal assistance treaties between Sierra Leone and Country Y, if any,
  • Explore alternative means of notification (e.g., service by mail, public notice), consistent with fair trial requirements.

Outcome:
The Court must rely on voluntary cooperation or indirect legal channels; there is no direct binding mechanism for third states.


Case Scenario 6 – Residual Functions and the RSCSL
Facts:
Years after the SCSL has largely wound down, issues arise regarding enforcement of sentences and witness protection. The Residual Special Court for Sierra Leone (RSCSL) takes over.
Legal Issues:

• Must Sierra Leone cooperate with the RSCSL in the same way?
• What about third states hosting convicts?

Solution:

• Article 11 of the RSCSL Agreement replicates the cooperation obligations of Article 17, mutatis mutandis.
• Sierra Leone must therefore:
  • Continue cooperating in witness protection,
  • Assist in enforcement measures,
  • Respond to RSCSL requests and orders.
• States that have agreed to enforce sentences (hosting imprisoned convicts) are bound by the terms of their enforcement agreements, not by Article 17.

Outcome:
The cooperation model extends into the residual phase, ensuring continuity of obligations for Sierra Leone.


Case Scenario 7 – Joint Investigation with Another International Tribunal
Facts:
The SCSL and another tribunal (for example, the International Criminal Court (ICC)) both investigate crimes with overlapping evidence and witnesses.
Legal Issues:

• How does Sierra Leone manage its cooperation obligations?
• Could there be conflicts between different courts?

Solution:

• Sierra Leone is obliged to cooperate with the SCSL under Article 17, and may separately agree to cooperate with the ICC or other tribunals.
• In case of conflicting requests (e.g., scheduling witnesses, custody issues), Sierra Leone should:
  • Engage in consultations with both institutions,
  • Seek sequencing or joint arrangements,
  • Prioritize obligations based on:
    • treaty commitments, and
    • practical feasibility.
• Ideally, tribunals coordinate their requests to avoid overburdening the state.

Outcome:
Cooperation duties can be managed through coordination and dialogue, though they may create strain on limited national resources.


Case Scenario 8 – Invitation to a Third State to Freeze Assets
Facts:
The SCSL learns that assets of an accused are held in Country Z (a third state with no treaty obligation). The Court wants those assets frozen to secure potential reparations or fines.
Legal Issues:

• Can the SCSL legally require Country Z to freeze assets?
• What can be done?

Solution:

• There is no legal obligation on Country Z to comply, absent Security Council action or a specific treaty.
• Under Rule 8(C), the Court may:
  • Invite Country Z to freeze the assets,
  • Provide legal and factual justification, appealing to:
    • international solidarity,
    • the seriousness of the crimes,
    • human rights considerations.
• Country Z may voluntarily choose to cooperate or may refuse.

Outcome:
The effectiveness of financial measures involving third states depends entirely on voluntary cooperation or broader political processes (e.g., Security Council action).


Case Scenario 9 – Sierra Leone Requests Court Assistance in Domestic Prosecution
Facts:
Sierra Leone wants to prosecute a mid-level perpetrator domestically. It asks the SCSL for access to witness statements and evidence collected in previous SCSL proceedings.
Legal Issues:

• Is the SCSL obliged to cooperate the other way around?
• How does this fit into the hybrid model?

Solution:

• The SCSL’s founding arrangements aim at complementarity with Sierra Leone’s justice system.
• While Article 17 focuses on state cooperation with the Court, the institutional design and practice encourage two-way cooperation where:
  • The SCSL shares appropriate materials, subject to:
    • witness protection measures,
    • confidentiality,
    • fair trial guarantees.
• This strengthens national capacity and legacy.

Outcome:
The hybrid model allows for mutual support, not just one-way obligations.


Case Scenario 10 – Replicating the SCSL Model in Another Country
Facts:
Country Q experiences a brutal civil conflict and approaches the United Nations to establish a court similar to the SCSL via a bilateral agreement.
Legal Issues:

• Is the SCSL model (an agreement between one state and an international organization) legally and politically viable in other contexts?
• What lessons apply from cooperation arrangements?

Solution:

• The SCSL demonstrates that:
  • A hybrid court can be created through a treaty between the UN and a single state.
  • That state can assume primary cooperation obligations, similar to those in Article 17.
• However, challenges include:
  • Ensuring funding,
  • Securing voluntary cooperation from third states,
  • Managing perceptions of legitimacy.
• Future courts may consider:
  • Seeking Chapter VII backing for cooperation from all UN Member States,
  • Embedding stronger regional participation,
  • Clarifying residual functions from the outset.

Outcome:
The SCSL is an important precedent, but replication elsewhere would require careful adaptation to local political, legal, and regional realities.


IV. Critical Analysis of the SCSL Cooperation Regime and Model
1. Strengths

• Strong National Ownership:
  By making Sierra Leone the central cooperating state under Article 17, the Court operated in close partnership with the national authorities. This enhanced:
  • Local relevance,
  • Capacity building,
  • Perceptions of shared responsibility.
• Institutional Innovation:
  The SCSL (and later the RSCSL) showed that an international criminal court can be:
  • Created not only by multilateral treaties or Chapter VII resolutions, but also by a bilateral agreement between a state and an international organization.
• Flexibility with Third States:
  Allowing the Court to invite cooperation from third states under Rule 8(C) offered a diplomatic channel without over-politicizing the legal framework.

2. Weaknesses and Limitations

• No Binding Duty on Third States:
  The Court’s inability to compel cooperation from other states significantly weakened its:
  • Enforcement capacity, and
  • Ability to arrest suspects who left Sierra Leone or to trace and freeze assets abroad.
• Dependence on Voluntary Cooperation:
  Without Chapter VII powers, the Court had to rely on:
  • Political goodwill,
  • Bilateral diplomacy,
  • Moral pressure.
    This can be unreliable and uneven, especially when powerful states are involved.
• Fragmentation Compared to ICTY/ICTR:
  Unlike the ICTY and ICTR, which enjoyed binding cooperation obligations on all UN Member States, the SCSL’s weaker framework risked:
  • Allowing safe havens,
  • Undermining deterrence.

3. Broader Significance of the SCSL Model

• A Laboratory for Hybrid Justice:
  The SCSL represents a test case for hybrid courts. It shows both:
  • What can be achieved with a willing host state, and
  • What limitations arise without global enforcement backing.
• Transferable Lessons:
  Future hybrid courts can draw from the SCSL and RSCSL by:
  • Combining strong domestic cooperation duties (like Article 17)
  • With wider regional or UN-based cooperation obligations, possibly via Chapter VII.
• Open Questions:
  • Will states and the United Nations find this model attractive enough to replicate?
  • Can such courts achieve sufficient independence and enforcement power without full UN backing?
