When a case that an interest group is interested in but not actually sponsoring comes before court the group can?

When a case of interest arises that an interest group is not sponsoring, the group can file an amicus curiae brief to provide the court with additional information, perspectives, or arguments relevant to the case. This allows the group to influence the court's decision without being a direct party to the lawsuit. Additionally, they may engage in lobbying efforts, public campaigns, or outreach to raise awareness about the case and its implications.
