How It Works in Practice
An amicus curiae is someone who is not a party to a legal case but offers information, expertise, or insight to help the court make a well-informed decision. These 'friends of the court' submit briefs or participate in hearings to provide perspectives that the parties involved might not fully represent. In international law or diplomacy, amicus curiae briefs can be crucial in cases involving complex issues like human rights, sovereignty, or Treaty Interpretation.
Why It Matters
The involvement of amicus curiae enriches the judicial process by broadening the scope of information and arguments considered. This is especially important in politically sensitive or complex cases where the court's decision could have widespread implications beyond the immediate parties. By providing neutral or expert viewpoints, amici curiae help ensure that courts consider the broader legal, social, or diplomatic context.
Amicus Curiae vs. Party to the Case
Unlike the plaintiff or defendant, an amicus curiae does not have a direct stake in the outcome. Their role is advisory rather than adversarial. This distinction means courts rely on amici to present impartial analyses or highlight overlooked issues, rather than to advocate for one side's interests.
Real-World Examples
A notable example is the International Court of Justice (ICJ) allowing amicus curiae submissions in cases involving state sovereignty or human rights. For instance, NGOs or states have submitted amicus briefs in cases concerning maritime boundaries or humanitarian law to assist the court with specialized knowledge.
Common Misconceptions
Some people believe amicus curiae can decide the outcome of a case, but they only provide supplementary information. Also, not every third party can file an amicus Brief; courts usually have rules about who can participate and under what conditions.
US Supreme Court Amicus Practice
The US Supreme Court has the most-developed amicus practice in any single court. Major SCOTUS cases routinely attract dozens of amicus briefs from civil-society organizations, professional associations, state attorneys general, foreign governments, and academic groups. The 2015 Obergefell v. Hodges (same-sex marriage) case attracted 148 amicus briefs; the 2022 Dobbs (abortion) case attracted over 130. The volume itself shapes the Court's understanding of issues with broader social implications and provides venues for groups affected by litigation outcomes to express their positions.
Example
In the landmark case concerning maritime boundaries, several states submitted amicus curiae briefs to provide expert legal and geographic insights to the International Court of Justice.
