The Supreme Court of the United States has adopted a revised version of the Rules of the Court. The new Rules will take effect on July 1, 2019.

The revisions to the Rules include substantive changes to Rules 14.1(b), 15.2, 25.3, 29.1, 29.2 and 33.1(g). Changes to Rules 14.1(b) and 15.2 require parties to identify any trial and appellate court cases that are directly related to the case in this Court. This provision is designed to assist the Justices in determining whether their participation in a case before joining the Court might necessitate recusal. An amendment to Rule 25.3 requires that a reply brief in a case scheduled for argument be received by the Clerk not later than 2 p.m.10 days before the date of argument; the current rule requires that a reply be submitted seven days before argument. Amendments to Rules 29.1 and 29.2 make explicit that paper remains the official form of filing. Modifications to Rule 33.1(g) reduce the number of words that are permitted for merits briefs.

The revisions are available on the Court's website: The revisions are accompanied by "Clerk's Comments." These are not part of the Rules, but are furnished to assist readers in understanding the changes.
