Explores the modern history, people, decisions, and conformations of the Supreme Court of the United States.

Production
Showtime Documentary Films asked if Dawn Porter would be interested in making a project revolving around the Supreme Court, to which Porter agreed. Initially, titled Confirmed, the project primarily focusing on how justices are confirmed, however, once the court began making conservative decisions, it was expanded to show how the court became political. Porter wanted the series to make people understand what is happening and how we got here. Over several thousand pieces of archive were looked over to construct the series. Porter reached out to justices for comment, but all declined to participate. News of gifts from wealthy donors to Clarence Thomas and Samuel Alito does not appear in the series, as the news came once the series was completed.

In June 2022, it was announced Porter would direct and executive produce a documentary series revolving around the Supreme Court of the United States for Showtime.
