Credible Commitments and the International Criminal Court

International Criminal Court (ICC): Created to prosecute war crimes.
Puzzle: Why was the ICC created and why do states join?
- It intrudes upon national sovereignty (states' rights to administer justice).
- Over 100 states have ratified the Rome Statute, creating the ICC.
Contrasting Views: Scholars argue the ICC is either harmful or ineffective.
Key Argument: ICC as a mechanism for states to self-bind—commit to avoid atrocities.

States that are both vulnerable to ICC cases and the least democratic tend to join the ICC.
Countries with robust domestic accountability mechanisms exhibit reluctance to ratify.
Evidence suggests that ratifying states take preliminary steps toward reducing violence and promoting peace.

Date of First Ratification: Senegal became the first signatory on February 2, 1999.
Notable Opposition: Major actors, like the U.S., opposed the ICC.
International Agreements: Long history of definitions for crimes, but lack of enforcement prior to ICC's establishment.
Change in Approach: ICC signals a shift in how nations view their judicial roles at international levels.

Credible Commitment Theory: Provides framework for understanding state behavior towards ICC.
Weak governments desire to bind themselves to avoid future violence.
**Counterintuitive Findings:
- Autocracies that have faced internal conflict often join ICC to self-limit power and enhance credibility.
- Democratic states with recent conflicts are less likely to join the ICC.

ICC’s design promotes binding commitments from states through legal obligations.
Rome Statute Characteristics:
- Limits states' ability to decline ICC jurisdiction on case-by-case basis.
- Gives ICC prosecutor the power to initiate cases independently.
- Provisions restrict states from making reservations regarding the statute’s articles.
Complementarity Principle: ICC complements domestic legal systems, intervening only when states fail to prosecute genuinely.
Judicial authority over serious crimes, including genocide and war crimes.

Concerns about sovereignty and potential accountability for leaders' actions create reluctance for some states.
Peacekeepers and military capabilities impact states' decisions to join ICC; stronger militaries may prefer non-commitment.
Utilizing the ICC: States may leverage ICC's authority against political opponents domestically—perceived as a legitimate avenue for accountability.

Event History Analysis: Examines ratification patterns and motivations for joining the ICC.
Key Hypotheses:
- Low credibility states with a history of civil wars are more likely to ratify
- High credibility states are less likely to ratify given recent civil conflicts.
Results:
- Nondemocracies have a significantly higher likelihood of ICC ratification post-civil conflicts.
- Notable contrast between civil strife and stable governance.

Ratification associated with positive shifts towards civil conflict resolution.
Statistical Findings:
- Ratified states, especially those with weak accountability, have increased chances of conflict cessation.
- Less accountable governments likely to experience peace processes following ratification.
No substantial evidence suggesting merely signing has the same positive impact as ratification.

The ICC is not simply a symbolic institution; it represents a serious commitment to judicial accountability.
Key Observations:
- Voluntary commitment to ICC often arises from states' struggles with internal violence.
- Self-binding through ICC can foster stable governance and justice.
Further research needed to validate these claims through longitudinal studies.
