"Amici curiae" who do "not" file briefs often present an academic perspective on the case. For example, if the law gives deference to a history of legislation of a certain topic, a historian may choose to evaluate the claim from their specialized expertise. An economist, statistician, or sociologist may choose to do the same. Newspaper editorials, blogs, and other opinion pieces arguably have the capability to influence Supreme Court decisions as "de facto amici curiae". They are not, however, technically considered "amici curiae," as they do not submit materials to the Court, do not need to ask for leave, and have no guarantee that they will be read.
