"Amicus briefs have the potential to exert significant influence on a decision, despite their ―delusive innocuousness.
amici curiae—non-parties who are nevertheless advocates, who are not bound by rules of standing and justiciability, or even rules of evidence, and who can present the court with new information and arguments—occupy a unique place in the appellate court. "
"Amicus curiae participation has surged in recent years, primarily by interest and advocacy groups wishing to advance their law reform efforts and to gain publicity."
