The Impact of Amicus Briefs on Supreme Court Conservatives

Amicus briefs filed by conservative legal activists, including Princeton Professor Robert P. George and Leonard Leo, have influenced Supreme Court rulings by promoting historical falsehoods. These briefs have been used to support conservative arguments in cases involving abortion, affirmative action, LGBTQ+ rights, and more. Leo and his network of nonprofit groups have connections to a majority of amicus briefs filed on behalf of conservative parties in high-profile rulings. Major historical organizations have criticized the use of these briefs, stating that they perpetuate flawed interpretations of history. The influence of amicus briefs in shaping court opinions has raised concerns about the lack of vetting and disclosure processes for these filings.
