Transportation Security Oversight Board — Security Threat Appeal Procedures
Legal Authority
- 49 U.S.C. § 115 — Establishes the Transportation Security Oversight Board as a Cabinet-level interagency body chaired by the Secretary of Transportation; authorizes TSOB to review transportation security programs and hear appeals from TSA security threat determinations
- 49 U.S.C. § 46111 — Governs employment restrictions and appeal procedures for aviation workers subject to security threat determinations
- 6 CFR Part 126 — DHS implementing regulations governing TSOB Review Panel appeals; specifies 60-day appeal filing deadline, briefing schedule, record requirements, SSI handling, and standard of review
Key Mechanics
The Transportation Security Oversight Board (TSOB) is a Cabinet-level interagency body chaired by the Secretary of Transportation that provides the final administrative appeal from TSA security threat determinations under 49 U.S.C. § 115. When TSA issues a Determination of Security Threat (DST) — revoking a transportation worker's access credentials — the worker may first challenge the determination before a DOT Administrative Law Judge; the TSOB Review Panel then hears any appeal from the ALJ ruling. Under 6 CFR Part 126, a party must file a notice of appeal within 60 calendar days of the ALJ decision. TSA must deliver the full administrative record within 30 days; the appellant's opening brief is due 60 days after receiving the record; the appellee's response brief is due 60 days after that; the reply is due 30 days after the response. The Review Panel applies a bifurcated standard of review: substantial evidence for factual findings and de novo review for legal conclusions (§ 126.29). Classified evidence and Sensitive Security Information in the record are handled under separate security protocols — the individual may not see evidence the government cannot disclose without appropriate clearances. The Review Panel issues a written final agency action (majority required); after that decision, the individual may seek review in federal court under APA arbitrary-and-capricious or substantial-evidence standards.

What This Rule Does
When TSA determines that an airport worker, pilot, flight crew member, or other transportation industry worker poses a security threat — a "Determination of Security Threat" (DST) — that person can challenge the determination through a hearing before an Administrative Law Judge. If the ALJ rules against them, they can appeal to the Transportation Security Oversight Board (TSOB) Review Panel. Six CFR Part 126 governs exactly how that appeal works.
The Transportation Security Oversight Board itself is a Cabinet-level interagency body chaired by the Secretary of Transportation and including the Secretary of Defense, the Attorney General, and other senior officials. Its role is to review TSA security policies and resolve appeals from security threat determinations. The Review Panel — a subset of TSOB — hears individual appeals from ALJ rulings.
This process matters enormously to transportation workers. A TSA security threat determination can cost you your job and effectively blacklist you from aviation, maritime, and other regulated transportation jobs. The TSOB Review Panel is the final administrative stop before federal court.
Key Provisions
- § 126.1 — The Review Panel reviews and resolves appeals of Administrative Law Judge decisions on Determination of Security Threat cases; the ALJ hearing is the first level of appeal after TSA's initial determination; the TSOB Review Panel is the second and final administrative appeal
- § 126.11 — Any party (the individual or TSA) may be represented by a lawyer licensed in any U.S. state, district, territory, or possession; each party pays their own counsel
- § 126.13 — To appeal an ALJ decision, file a written notice of appeal with the TSOB Docket Clerk within 60 calendar days of service of the ALJ's written decision; filing can be by email to the TSOB docket address or by mailing/delivering the notice
- § 126.15 — Within 15 calendar days of filing or being served with the appeal notice, each party must file a written entry of appearance identifying their counsel and service address
- § 126.17 — Within 30 calendar days of the appeal notice, TSA must notify the TSOB Docket Clerk whether the ALJ hearing record contains any classified information or Sensitive Security Information (SSI); classified information and SSI are handled under separate security protocols and cannot be disclosed to the individual without appropriate clearances
- § 126.19 — TSA must deliver the complete administrative record to the TSOB Docket Clerk within 30 calendar days of the appeal notice; the record includes the hearing transcript, all evidence admitted at the ALJ hearing, and the ALJ's decision and any supporting documents

- § 126.25 — Oral argument is not automatic; a party may request it in a brief or motion; the Review Panel may also order oral argument on its own initiative; if oral argument is ordered, each party has equal time
- § 126.27 — The Review Panel deliberates in private; draft decisions and notes made during deliberations are not subject to disclosure; the Review Panel issues a written decision that constitutes the final agency action
- § 126.29 — Standard of review: the Review Panel reviews the ALJ's factual findings for substantial evidence and the ALJ's legal conclusions de novo (fresh review without deference)
- § 126.31 — The Review Panel may affirm, reverse, or modify the ALJ decision; it may also remand to the ALJ for additional proceedings; a majority of panel members must agree on the outcome
- § 126.33 — If the Review Panel upholds the security threat determination, the individual is subject to the access revocation and employment consequences from TSA's underlying determination; the Review Panel's decision is the final administrative action and may be appealed to federal court
How It Affects You
If TSA has issued a Determination of Security Threat against you, this process is your administrative appeal track. You must exhaust administrative remedies (ALJ hearing + TSOB appeal) before you can challenge TSA's determination in federal court.
Key timelines to know:
- 60 days to file your notice of appeal from the ALJ decision
- 15 days to enter your appearance after filing
- 60 days to file your opening brief after receiving the record
- Total administrative appeal timeline: typically 6–18 months
Classified and SSI evidence creates unique challenges. TSA may rely on classified or Sensitive Security Information that you and your lawyer cannot see without security clearances. The TSOB has procedures for handling such information, but it means you may be fighting a determination based partly on evidence you cannot directly review or rebut.
Federal court review is available after the TSOB Review Panel issues its final decision. Courts typically review TSOB decisions under the Administrative Procedure Act standard — upholding the agency's decision unless it is arbitrary, capricious, contrary to law, or unsupported by substantial evidence.
Who is affected: Airport workers who need unescorted access to secured areas, commercial pilots, flight crew members, maritime workers at regulated ports, and others who hold or seek TSA security credentials. A security threat determination bars you from the job and from the credential — the stakes are high.
