When must counsel receive notice of a supporting certiorari response?

Confirm when the case was docketed in the Supreme Court.

Confirm that the respondent was aligned with petitioner below and now supports granting the petition.

Identify counsel of record for every party and obtain evidence that each received the notice. Do not substitute a Court-upload timestamp or a mailing date.

1. Use actual Supreme Court docketing. Arrange receipt by every required counsel, not merely dispatch.
2. Exclude the established trigger day.
3. Count 20 calendar days.
4. Apply Rule 30.1 final-day adjustment.
5. Complete the required receipt of notice by that date.

Supreme Court Rule 30.1 excludes the trigger day and includes every intermediate calendar day. For periods shorter than seven days it excludes intermediate closed days. Each fixed period reviewed here is at least seven days.

Count from docketing to the Rule 30.1-adjusted final day. Counsel must arrange actual receipt by then. The calculator does not calculate delivery lead time or prove receipt.

If the final day is Saturday, Sunday, a federal legal holiday listed in 5 U.S.C. 6103 or a Court-building closure ordered by the Court or Chief Justice, Rule 30.1 continues the period to the next day that is none of those. Check actual Court closure orders. The calculator does not infer additional closures.

Fictitious example

Fictitious Supreme Court docketing on August 25, 2026. An aligned respondent intends to support granting the petition and must arrange receipt by every party’s counsel. Exclude the established trigger day, August 25, 2026. Counting 20 calendar days reaches September 14, 2026. The final day is an open weekday.

Fictitious facts and dates. No different schedule, additional Court closure or extension is assumed.

Other respondent positions

Rule 12.6 exempts the specified unaligned supporting respondent and aligned respondent seeking denial from this notice requirement. Check both alignment and position.

Every required recipient

Receipt by one counsel does not establish receipt by all parties’ counsel of record. Preserve the complete recipient list and evidence.

Separate response

The supporting response remains due within the separate nonextendable 30-day docket-based period. Notice does not replace it.

• The calculator counts the encoded default period after an established trigger. It does not determine jurisdiction, party alignment or the effect of a particular order.
• Check the Court’s docket, actual directions and proof of the required act.

• Confirm that Rule 12.6’s special notice requirement applies.
• Identify every party’s counsel of record.
• Use the actual Supreme Court docketing date.
• Arrange and document receipt by each required counsel within the period.
• Separately prepare and file the supporting response.
• Rule 12.6 requires counsel of record for every party to receive the notice. A Court filing, postmark or electronic docket notification does not prove that every required recipient received it. Preserve receipt evidence.
• Preserve evidence of the required recipients and actual delivery or service.
