Bilateral Immunity Agreement

An agreement between two states to protect each other's nationals from surrender to the International Criminal Court without consent.

Updated April 23, 2026


How It Works in Practice

Bilateral Immunity Agreements (BIAs) are treaties between two countries that agree not to surrender each other's nationals to the International Criminal Court (ICC) without consent. These agreements are designed to protect citizens from international prosecution unless the home country agrees to it. Typically, one state is a party to the ICC, and the other seeks to shield its nationals from ICC jurisdiction by entering into a BIA.

When a BIA is in place, if one country requests the other to hand over a national suspected of international crimes, the receiving country is obliged to refuse or seek consent before transferring that individual to the ICC. This mechanism effectively limits the ICC’s reach over those nationals, preserving national sovereignty over legal matters involving their citizens.

Why It Matters

The significance of Bilateral Immunity Agreements lies in the tension between international justice and state sovereignty. The ICC aims to prosecute serious crimes like genocide and war crimes, but some countries view this as interference in their internal affairs. BIAs allow states to protect their nationals from external prosecution, which they argue is essential for maintaining their judicial independence.

However, critics contend that BIAs can undermine the ICC’s ability to hold individuals accountable for international crimes, potentially enabling impunity. For states that have experienced conflict, BIAs can be controversial because they may shelter individuals accused of serious offenses, preventing international scrutiny.

Bilateral Immunity Agreements vs Other ICC Agreements

BIAs are often confused with other ICC-related treaties, such as the Rome Statute itself or multilateral agreements that support ICC jurisdiction. Unlike the Rome Statute, which establishes the ICC and its jurisdiction, BIAs are separate and bilateral, focusing solely on immunity from surrender without consent.

Another related concept is the principle of complementarity, which means the ICC acts only when national courts are unwilling or unable to prosecute. BIAs may interfere with this principle by preventing national courts from surrendering suspects, even if they are unwilling to prosecute, thereby limiting the ICC’s complementary jurisdiction.

Real-World Examples

One notable example is the United States, which has signed numerous BIAs with countries around the world to protect its military personnel and officials from ICC prosecution. The U.S. is not a party to the Rome Statute and has pursued BIAs to safeguard its nationals from the Court’s jurisdiction.

Similarly, some African nations have debated BIAs amid concerns about perceived biases in ICC prosecutions. These agreements have played a role in the political dynamics between the ICC and member states.

Common Misconceptions

A widespread misconception is that BIAs completely exempt nationals from all forms of international accountability. In reality, BIAs only restrict surrender to the ICC without consent; they do not provide blanket immunity from prosecution by other international bodies or national courts.

Another misunderstanding is that BIAs are universally accepted. In fact, many ICC member states oppose BIAs because they can obstruct international justice efforts and contradict the spirit of the Rome Statute.

Example

The United States signed Bilateral Immunity Agreements with multiple countries to protect its military personnel from ICC prosecution despite not being a party to the Rome Statute.
