Labor & Employment Law Daily Wrap Up, OPM NEWS—New federal service probationary and trial period appeal system finalized, (Aug 3, 2026)

By WK Editorial Staff

The rule removes the MSPB as the primary forum for probationary-period appeals.

The Office of Personnel Management (OPM) has issued a final rule establishing a new administrative framework for appeals arising from terminations during federal probationary and trial periods. Effective September 2, 2026, the rule replaces the rescinded Merit Systems Protection Board (MSPB) appeal process with a limited OPM-administered adjudication system.

The rule creates a new 5 C.F.R. Part 751 and designates OPM as the adjudicatory forum for covered probationary and trial period appeals. Prior MSPB procedures became inoperative following Executive Order 14284, “Strengthening Probationary Periods in the Federal Service,” issued April 24, 2025. The final rule implements the President's delegation of authority to OPM to establish replacement appeal procedures.

The most significant changes include:

• Removal of the MSPB as the primary forum for probationary-period appeals.

• Creation of an OPM-run appeal process with electronic filing and record-based adjudication.

• Limitation of appealable claims to discrimination based on partisan political reasons; discrimination based on marital status; and specified procedural violations involving terminations based in whole or in part on conditions existing before appointment.

• Elimination of the prior practice of attaching federal-sector EEO claims to probationary appeals. Such claims must instead proceed through the EEOC's established processes.

• Establishment of reconsideration procedures and limited Director review within OPM before decisions become final.

The rule also covers certain supervisory and managerial probationary actions and certain excepted-service employees appointed under 5 C.F.R. Part 307, while generally excluding other excepted-service trial period employees absent separate statutory authority.

Legal authority. OPM grounds the rule primarily in:

• Executive Order 14284 and Civil Service Rule XI;

• 5 U.S.C. §§ 1103 and 1104, concerning OPM's administration of the civil service system; and

• 5 U.S.C. § 3321(a), which authorizes the President to prescribe regulations governing when competitive service appointments become final.

The agency repeatedly emphasizes that probationary employees generally lack statutory MSPB appeal rights under the Civil Service Reform Act (CSRA). According to OPM, MSPB jurisdiction over probationary appeals existed largely by regulation rather than by congressional mandate, allowing OPM to redesign the process after Executive Order 14284 rescinded the prior regulations.

The rule also relies on longstanding precedent recognizing probationary periods as an extension of the examination and assessment process rather than a period of tenured employment. OPM cites the CSRA, historical Civil Service Commission practice, and federal court decisions emphasizing agency discretion to separate probationary employees before appointments become final.

OPM's rationale. The central premise of the rule is that probationary and trial periods should remain effective management tools permitting agencies to assess employee suitability before granting the protections associated with completed service. OPM argues that MSPB litigation procedures, including discovery, hearings, petitions for Board review, and potential judicial review, imposed costs and delays disproportionate to the limited rights available during probationary service.

OPM cited historical studies from the MSPB, Government Accountability Office, and OPM surveys suggesting that agencies frequently fail to use probationary periods effectively and are often reluctant to remove poor performers before those employees acquire additional procedural protections. According to OPM, litigation risk and procedural burden contribute to that reluctance.

The agency contends that the new framework:

• reduces adjudicative costs and delay;

• encourages more meaningful use of probationary periods;

• preserves limited review for unlawful actions;

• maintains agency flexibility during the assessment period; and

• provides greater consistency with Civil Service Rule XI.

Procedural features. Appeals generally must be filed within 30 days and will be adjudicated primarily on the written record. Agencies must produce a complete administrative record supporting the challenged action, and appellants may file replies. OPM retains authority to request additional information, conduct investigations or audits, and hold hearings when necessary to resolve material factual disputes or credibility issues.

The rule places the burden on appellants to establish timeliness, jurisdiction, and the existence of an appealable claim. Final merits decisions will be published, subject to privacy and legal restrictions, in an effort to promote consistency and transparency.

Judicial review and other fora. One of the rule's most consequential features is OPM's position that decisions issued under Part 751 are not subject to judicial review. OPM argues that neither the CSRA nor any other statute grants a right to seek court review of final OPM decisions in these probationary appeal matters.

At the same time, the rule preserves access to other fora where an independent legal basis exists. Employees may continue to pursue:

• EEO claims through agency EEO procedures and the EEOC;

• prohibited personnel practice claims through the Office of Special Counsel;

• veterans' rights claims where authorized by statute; and

• MSPB appeals where independent statutory jurisdiction exists.
