When must a person seek intervention in an agency review proceeding?

Identify the agency proceeding and actual petition-for-review filing.

Check whether the applicable statute provides another intervention method.

Identify the proposed intervenor’s interest and grounds for intervention.

Read actual circuit requirements and case directions before using the scoped national period.

1. Establish the scoped procedure and actual filing event.
2. Exclude that filing day.
3. Count 30 calendar days.
4. Check final-day holidays, inaccessibility and applicable directions.

Exclude the verified filing day and count every calendar day under FRAP 26(a)(1). If the final day is Saturday, Sunday or a legal holiday, continue to the next open day. Check actual inaccessibility and any applicable order.

FRAP 26(a)(6) includes the listed federal holidays and holidays declared by the President or Congress. For a period after an event it also includes applicable state holidays, including the state of the circuit clerk’s principal office. Establish the actual circuit and applicable calendar for this agency proceeding. The national calculator does not infer additional state holidays, inaccessibility or granted relief.

These clocks start from filing rather than service. Rule 26(c) does not add three days merely because a copy of the triggering paper was served.

Fictitious example

In a fictitious scoped proceeding, the petition for review is filed on July 6, 2026. Exclude July 6 and count 30 calendar days. August 5, 2026 is the assumed open final day, with no extra state holiday, inaccessibility or different court direction.

Fictitious dates. Assume this national procedure applies with no extra holiday, inaccessibility or different direction. The calculation does not establish jurisdiction, intervention leave or accepted filing and service.

Statutory alternative method

Rule 15(d) begins with an exception where a statute provides another method. The calculator does not research or select that statutory method.

Motion and required statement

The motion or authorized statutory notice must contain a concise statement of the moving person’s interest and grounds for intervention.

All-party service

The national motion procedure requires filing with the circuit clerk and serving a copy on all parties.

Permission is separate

A timely filed motion requests leave. The calculation does not establish that the court granted intervention or that the interest and grounds are sufficient.

Different filing clocks

Rule 15(a)(1) requires a petition for review within the time prescribed by law. The intervention period does not establish the petition’s statutory deadline.

• This guide does not establish current statutory review jurisdiction, a petition-for-review statutory period or entitlement to intervention.
• Confirm actual circuit-local requirements and case orders before completing filing and service.

• Verify actual petition-for-review filing.
• Check any statutory alternative intervention method.
• State the moving person’s interest and grounds concisely.
• File with the circuit clerk and serve all parties under the applicable method.
• Preserve accepted filing, service and the actual court disposition.
• Electronic court-of-appeals filing ends at midnight in the circuit clerk’s principal-office time zone under FRAP 26(a)(4)(B). Ordinary paper filing requires circuit-clerk receipt and ends at scheduled office closure. The brief/appendix dispatch exception does not itself cover these answers, motions or proposed judgments. Represented persons ordinarily file electronically under Rule 25. Confirm current local instructions, permitted channels, separate required service and actual inaccessibility.
