How to Challenge an Occupational Physician’s Unfitness Declaration Within 15 Days

The occupational physician has just issued an unfitness declaration, and you disagree? Whether you are an employer or an employee, there is a specific recourse available before the conseil de prud’hommes (labor tribunal) — but be aware, the timeframe is only 15 days. After this period, the declaration becomes definitive and is binding on all parties, including the judge. Here’s how to effectively contest an unfitness declaration.

What Recourse is Available Against an Occupational Physician’s Unfitness Declaration?

The Labour Code provides for a specific recourse before the conseil de prud’hommes to challenge medical opinions from the occupational health service that “are based on medical elements”: fitness declarations, unfitness declarations, and recommendations for workplace adjustments. This recourse allows the judge to assess the validity of the declaration, potentially with the assistance of a medical expert appointed by the court.

This recourse is the only mechanism to challenge the medical qualifications (fit/unfit) and the scope of the recommendations. No other legal avenue — particularly in the context of subsequent dismissal disputes — allows for the validity of the declaration to be contested once the timeframe has expired.

What is the Timeframe to Challenge an Unfitness Declaration?

The timeframe is 15 days from the receipt of the declaration by the challenging party (not from the date of issuance by the physician). This timeframe has an absolute extinguishing effect: after 15 days, the declaration binds the parties and the labor tribunal judge. It is no longer possible to contest:

• The validity of the declaration.
• Its contents (including minor errors such as the job title).
• The actions of the physician (compliance with Article R. 4624-42).

The Court of Cassation has confirmed it unequivocally: “after the fifteen-day period, the decision of the occupational physician binds the parties and the judge” (Cass. soc., December 7, 2022, n° 21-23.662; October 25, 2023, n° 22-18.303).

How to Prove the Date of Receipt of the Declaration?

The certain date of notification is crucial as it triggers the timeframe. Valid proof includes:

• An acknowledgment of receipt of a registered letter (LRAR).
• Personal hand delivery with a dated and signed receipt.
• A reliable electronic acknowledgment with timestamp.

Caution: Hand delivery without signature or acknowledgment does not start the timeframe. The Court of Cassation has been very clear on this point (Cass. soc., March 2, 2022, n° 20-21.715). Likewise, subsequent notifications (via simple email or a second letter) do not retroactively correct the absence of a certain date during the initial delivery (Cass. soc., December 4, 2024, n° 23-18.128).

Practical Advice for Employers: As soon as the declaration is delivered, have a receipt signed with the date and retain it carefully. This document will serve as proof in case the starting point of the timeframe is contested.

Who Can Contest the Unfitness Declaration?

The recourse is available both to the employee and the employer, each for their own grievances:

• Employees can contest if they believe that the unfitness is unjustified or that the physician’s recommendations are inappropriate.
• Employers can contest if they feel that the declaration is overly restrictive (e.g., if no reclassification is granted when it should be) or if the imposed restrictions are disproportionate.

How to Bring a Case Before the Conseil de Prud’hommes?

The case is initiated before the conseil de prud’hommes, often in summary proceedings (accelerated procedure). Here are the standard requests to make:

1. Appointment of a medical expert to examine the employee and assess the validity of the declaration.
2. Disclosure to the judge of the medical elements relied upon by the occupational physician (under medical confidentiality).
3. Confirmation or refutation of the unfitness declaration.
4. If necessary, request for a new medical examination.

Important Point: The referral to the CPH is not suspensive. The employer must continue with the procedure in parallel: searching for reclassification, consulting the CSE (Social and Economic Committee), respecting the D+30 timeframe for salary resumption.

What Strategy to Adopt During the Contestation?

Contesting the declaration creates a dual track situation that the employer must manage diligently:

Track A: Judicial Recourse

• Submit the request within the 15 days.
• Prepare the medical and factual elements for the expert.
• Wait for the CPH’s decision.

Track B: Reclassification Procedure (in parallel)

• Continue the search for reclassification (unless a valid exemption applies).
• Consult the CSE.
• Adhere to D+30 — salary resumption is due even during the recourse (Cass. soc., January 10, 2024, n° 22-13.464).

The key question concerns the timing of the termination decision: if the recourse has a good chance of success, it may be prudent to postpone the notice of dismissal until the CPH’s decision to avoid dismissing based on a declaration that may be overturned. Conversely, one must anticipate the cost of resuming salary at D+30.

What Happens Depending on the Outcome of the Recourse?

The Declaration is Confirmed

The procedure resumes its normal course: the employer continues (or concludes) the search for reclassification and, if necessary, proceeds with dismissal due to unfitness and impossibility of reclassification.

The Declaration is Overturned

The situation changes radically: there is no longer unfitness, and therefore no legal basis for dismissal due to unfitness. The employer must reintegrate the employee into their position (possibly adjusted) or, if a new examination is ordered, wait for its conclusions.

No Recourse Filed Within 15 Days

The declaration becomes definitive and irrevocable. The employer follows the standard procedure: reclassification → CSE → offers → decision (effective reclassification or dismissal).

What Errors in the Declaration Can Be Contested?

The D+15 recourse covers all medical aspects of the declaration, including:

• The classification of unfitness itself.
• The scope of the recommendations (restrictions, adjustments).
• The presence or absence of a waiver for reclassification.
• Factual errors in the declaration (incorrect job title, questionable mentions).

Trap to Avoid: Factual errors must be explicitly contested via the D+15 recourse. They can no longer be invoked in subsequent dismissal disputes (Cass. soc., October 25, 2023, n° 22-18.303). Do not let the timeline pass by thinking that the error is “minor”.

Operational Script: Contesting an Unfitness Declaration in 4 Steps

1. Timestamp: Document both the issuance date AND the receipt date of the declaration (with supporting documents).
2. Decide Within 10 Days: “Shall we contest?” If yes, refer to the CPH and prepare the requests (expert, disclosure of elements, new examination).
3. Proceed in Parallel: Continue the search for reclassification and the CSE sequence while maintaining a log with evidence.
4. Synchronize: Upon the CPH’s decision, revise the plan — if the declaration is confirmed, continue; if it is overturned, recalibrate accordingly.

Documents to Keep to Secure the File

• Unfitness declaration (original version).
• Proof(s) of receipt (AR, acknowledgment, timestamp).
• Correspondence and emails exchanged with the occupational health service.
• CPH request and any order.
• Expert report and conclusions from the medical expert.
• Log of the reclassification search.
• CSE minutes.
• Reclassification offers and employee responses.
• Termination letter or reclassification actions.

FAQ — Contesting the Unfitness Declaration

Is the 15-Day Deadline a Strict Deadline?

The deadline runs from the day of receipt of the declaration. It is a calendar 15-day deadline. The referral to the CPH must occur within this timeframe; otherwise, the declaration becomes definitive.

Can the Declaration be Contested After Termination?

No. If the 15 days have elapsed without recourse, the declaration is definitive. The employee will not be able to contest the declaration in subsequent dismissal disputes (Cass. soc., December 7, 2022, n° 21-23.662).

Must the Employer Continue the Procedure During the Contestation?

Yes. The referral to the CPH is not suspensive. The employer must continue reclassification searches and comply with the D+30 deadline for salary resumption.

What If the Date of Receipt Cannot Be Proven?

If there is no proof of a certain date, the 15-day deadline does not start. The employer has a vested interest in securing this proof immediately upon notification to avoid a late contestation.

Employer’s Obligations in Terms of Health and Safety at Work

The employer is bound by an obligation of safety towards its employees, based on Article L.4121-1 of the Labour Code. It must take necessary measures to ensure the safety and protect the physical and mental health of workers, which includes:

• Measures for prevention of professional risks and hardship
• Information and training actions
• Organization and means adapted to the situation

These measures are based on the 9 general principles of prevention defined in Article L.4121-2: avoid risks, assess those that cannot be avoided, combat risks at the source, adapt work to the individual, take into account the state of technological progress, replace what is dangerous, plan for prevention, prioritize collective protective measures, provide appropriate instructions.

The Unique Document of Professional Risk Assessment (DUERP), required by Article R.4121-1, is mandatory in all companies from the first employee. It must be updated at least annually in companies with at least 11 employees and whenever there are significant changes in working conditions.

The law n° 2021-1018 of August 2, 2021, strengthening preventive healthcare at work, has expanded obligations regarding the DUERP, including requiring its storage for 40 years and its digital filing. Visit our Labour Law page for more details.

Managing Unfitness: Procedure and Obligations

A employee’s unfitness, established by the occupational physician according to the procedure outlined in Article L.4624-4 of the Labour Code, imposes an obligation of reclassification on the employer (Article L.1226-2 for non-professional unfitness, L.1226-10 for professional unfitness).

The procedure is as follows:

• The occupational physician acknowledges the unfitness after a medical examination and, if necessary, a position evaluation and assessment of working conditions.
• The employer has a one-month timeframe from the unfitness declaration to reclassify the employee or proceed with dismissal.
• The reclassification search must be fair and serious, covering all available positions within the company and group.
• The CSE must be consulted on the reclassification proposals (Articles L.1226-2 and L.1226-10).
• If reclassification is impossible (or if the occupational physician indicates that any job retention would be severely detrimental to health), the employer may proceed with dismissal for unfitness.

The Court of Cassation has reminded in a ruling Cass. soc., November 22, 2023, n° 22-12.678 that the employer cannot merely invoke the absence of available positions without justifying concrete efforts made for reclassification within the company and the group.
