What are some examples of important/influential Amicus briefs?
<p>I've been digging through Supreme court documents and it got me wondering - does anybody know any specific examples of Amicus briefs that may have changed the outcome of an important case?  I couldn't easily find any on google, so I figured I would ask here. Any court or any period of time is okay, really.</p>

<p>I don't study the law, but the Amicus brief seems like an interesting mechanism to me, perhaps one that could sway the majority opinion of a jury in an important precedent-setting case. </p>

<p>Amicus briefs are never seen by juries. They only guide judges, and in the vast majority of cases, only appellate court judges. They are predominantly filed in the U.S. Supreme Court, a state supreme court, or a U.S. Court of Appeals circuit's panel.</p>
<p>One of the most influential and most famous was <a href="https://blog.gale.com/the-aclus-role-in-brown-v-board-of-education/" rel="nofollow noreferrer">the ACLU's amicus brief in the <em>Brown v. Board of Education</em> case</a>, although there are hundreds of notable cases in which amicus briefs are influential, and dozens that are famous. The Anti-Defamation League (an organization devoted to fighting anti-semitism) <a href="https://www.adl.org/education/references/amicus-briefs/brown-v-board-of-education-of-topeka-us-supreme-court-1952" rel="nofollow noreferrer">also filed an influential amicus brief</a> in <em>Brown v. Board of Education</em>.</p>
<p>It is rarely possible to know with certainty how important a brief was (other than through echos of language or reasoning from the brief in the opinion itself), as judicial deliberations are generally strictly confidential.</p>
<p>In a far lower profile case, for example, I once litigated a case in the Colorado Supreme Court in which an amicus brief from the Colorado Bar Association was probably very influential.</p>
