This 'amicus brief' by The Brady Center to Prevent Gun Violence was submitted in a US Supreme Court case in 2008. Such a strategy could be useful for other IANSA members working on the Disarm Domestic Violence campaign in other countries.

An amicus brief is a document which is filed in a court by someone who is not directly related to the case under consideration. The additional information which is found in such a document can be useful for the judge evaluating the case, and it becomes part of the official case record. Many nations allow people or entities to file such documents with their courts.

The information may be a legal opinion in the form of a brief, a testimony that has not been solicited by any of the parties, or a learned treatise on a matter that bears on the case. The decision whether to admit the information lies with the discretion of the court.

Once an amicus brief is filed with a court, the court can decide whether or not to accept it. Such a brief may be rejected for any number of reasons, in which case it is not part of the final court record of the case, and it will not be considered in deliberations. In some regions, briefs filed by other states or territories are automatically accepted, as are briefs from the national government. The brief typically includes a description of who is filing it, and why, since an amicus brief is generally filed out of a desire to protect one's interests.

Like other aspects of legal procedure, an amicus brief follows a specific format and there are certain protocols which must be followed when filing such a document. If you are interested in filing an amicus brief, you should consult a qualified lawyer in your area.
