- 1. An amicus curiae brief that brings to the attention of the Court relevant matter not already brought to its attention by the parties may be of considerable help to the Court. An amicus curiae brief that does not serve this purpose burdens the Court, and its filing is not favored. An amicus curiae brief may be filed only by an attorney admitted to practice before this Court as provided in Rule 5.
- 2. (a) An amicus curiae brief submitted before the Court's consideration of a petition for a writ of certiorari, motion for leave to file a bill of complaint, jurisdictional statement, or petition for an extraordinary writ, may be filed if if it reflects that the written consent of all parties as been provided, or if the Court grants leave to file under subparagraph 2(b) of this Rule. An amicus curiae brief in support of a petitioner or appellant shall be filed within 30 days after the case is placed on the docket or a response is called for by the Court, whichever is later, and that time will not be extended. An amicus curiae brief in support of a motion of a plaintiff for leave to file a bill of complaint in an original action shall be filed within 60 days after the case is placed on the docket, and that time will not be extended. An amicus curiae brief in support of a respondent, an appellee, or a defendant shall be submitted within the time allowed for filing a brief in opposition or a motion to dismiss or affirm. An amicus curiae filing a brief under this subparagraph shall ensure that the counsel of record for all parties receive notice of its intention to file an amicus curiae brief at least 10 days prior to the due date for the amicus curiae brief, unless the amicus curiae brief is filed earlier than 10 days before the due date. Only one signatory to any amicus curiae brief filed jointly by more than one amicus curiae must timely notify the parties of its intent to file that brief. The amicus curiaebrief shall indicate that counsel of record received timely notice of the intent to file the brief under this Rule and shall specify whether consent was granted, and its cover shall identify the party supported. Only one signatory to an amicus curiae brief filed jointly by more than one amicus curiae must obtain consent of the parties to file that brief. A petitioner or respondent may submit to the Clerk a letter granting blanket consent to amicus curiae briefs, stating that the party consents to the filing of amicus curiae briefs in support of either or of neither party. The Clerk will note all notices of blanket consent on the docket.
- (b) When a party to the case has withheld consent, a motion for leave to file an amicus curiae brief before the Court's consideration of a petition for a writ of certiorari, motion for leave to file a bill of complaint, jurisdictional statement, or petition for an extraordinary writ may be presented to the Court. The motion, prepared as required by Rule 33.1 and as one document with the brief sought to be filed, shall be submitted within the time allowed for filing an amicus curiae brief, and shall indicate the party or parties who have withheld consent and state the nature of the movant's interest. Such a motion is not favored.
- 3. (a) An amicus curiae brief in a case before the Court for oral argument may be filed if it reflects that written consent of all parties has been provided, or if the Court grants leave to file under subparagraph 3(b) of this Rule. The brief shall be submitted within 7 days after the brief for the party supported is filed, or if in support of neither party, within 7 days after the time allowed for filing the petitioner's or appellant's brief. Motions to extend the time for filing an amicus curiae brief will not be entertained. The 10-day notice requirement of subparagraph 2(a) of this Rule does not apply to an amicus curiae brief in a case before the Court for oral argument. The amicus curiae brief shall specify whether consent was granted, and its cover shall identify the party supported or indicate whether it suggests affirmance or reversal. The Clerk will not file a reply brief for an amicus curiae, or a brief for an amicus curiae in support of, or in opposition to, a petition for rehearing. Only one signatory to an amicus curiae brief filed jointly by more than one amicus curiae must obtain consent of the parties to file that brief. A petitioner or respondent may submit to the Clerk a letter granting blanket consent to amicus curiae briefs, stating that the party consents to the filing of amicus curiae briefs in support of either or of neither party. The Clerk will note all notices of blanket consent on the docket.
- (b) When a party to a case before the Court for oral argument has withheld consent, a motion for leave to file an amicus curiae brief may be presented to the Court. The motion, prepared as required by Rule 33.1 and as one document with the brief sought to be filed, shall be submitted within the time allowed for filing an amicus curiae brief, and shall indicate the party or parties who have withheld consent and state the nature of the movant's interest.
- 4. No motion for leave to file an amicus curiae brief is necessary if the brief is presented on behalf of the United States by the Solicitor General; on behalf of any agency of the United States allowed by law to appear before this Court when submitted by the agency's authorized legal representative; on behalf of a State, Commonwealth, Territory, or Possession when submitted by its Attorney General; or on behalf of a city, county, town, or similar entity when submitted by its authorized law officer.
- 5. A brief or motion filed under this Rule shall be accompanied by proof of service as required by Rule 29, and shall comply with the applicable provisions of Rules 21, 24, and 33.1 (except that it suffices to set out in the brief the interest of the amicus curiae, the summary of the argument, the argument, and the conclusion). A motion for leave to file may not exceed 1500 words. A party served with the motion may file an objection thereto, stating concisely the reasons for withholding consent; the objection shall be prepared as required by Rule 33.2.
- 6. Except for briefs presented on behalf of amicus curiae listed in Rule 37.4, a brief filed under this Rule shall indicate whether counsel for a party authored the brief in whole or in part and whether such counsel or a party made a monetary contribution intended to fund the preparation or submission of the brief, and shall identify every person or entity, other than the amicus curiae, its members, or its counsel, who made such a monetary contribution to the preparation or submission of the brief. The disclosure shall be made in the first footnote on the first page of text.
