Final answer:

Step-by-step explanation:
Amicus curiae, which translates to "friend of the court," is a term used to describe a brief filed by individuals or groups who are not parties to a case but have a strong interest in the matter and wish to offer their perspectives and influence the court's decision. Such briefs provide the court with additional information, opinions, analysis, and recommendations that might not be brought forth by the actual parties involved in the litigation. Appellate courts frequently encounter amicus curiae briefs as they review the decisions made by lower courts. These briefs are tools that can help the appellate court grasp the wider implications of a legal decision beyond the immediate parties of the case.
