The General Code of Public Service establishes a strict principle: every public agent dedicates their entire professional activity to the tasks assigned to them. Article L. 123-1 prohibits the professional exercise of a lucrative private activity. However, agricultural activity benefits from special treatment in the regulations on cumulative activities. It is among the authorized ancillary activities, provided that a specific framework is respected that combines public service law and the realities of agricultural social status.
Agricultural social status and cumulative authorization: two distinct logics
The cumulative authorization granted by the employer administration and the affiliation to the MSA do not fall under the same examination. The former concerns the compatibility of the project with service obligations. The latter is based on specific criteria: area cultivated, agricultural working time, income from the operation.
An agent can therefore obtain their hierarchy’s agreement without meeting the MSA affiliation thresholds. The reverse can also occur: automatic affiliation by the MSA, based on the cultivated area, without the administrative situation being regularized on the employer’s side. These two processes follow independent criteria and must be conducted in parallel.
Many agents assume that a cumulative authorization grants them the status of an agricultural operator. This shortcut is false. It is possible to learn more on Capitaine Comment? to understand the connections between these two legal frameworks.
Ancillary agricultural activity: the authorization procedure with the employer
The decree of January 30, 2020, concerning ethical controls in the public service lists the ancillary activities that an agent can engage in with prior authorization. Agricultural activity is included in this list. The request, made in writing to the hierarchical authority, requires a response within one month.
A vague title (“helping on a farm”) is not sufficient. The administration expects a concrete description: type of structure envisaged, nature of tasks, expected frequency. A detailed request reduces the risk of a refusal based on a potential conflict of interest.

The hierarchical authority evaluates the request based on three criteria:
- The agricultural activity must not disrupt the normal functioning of the service nor encroach on the agent’s availability during their working hours.
- It must not create a conflict of interest as defined by Article 25 bis of the law of July 13, 1983, meaning any interference between public interest and private interests that could affect the impartial exercise of duties.
- It must neither undermine the dignity of the functions exercised nor compromise the principle of neutrality of public service.
A refusal of authorization must be justified. The agent can contest the decision through a gracious appeal, and if necessary, before the administrative tribunal.
Creation of an agricultural structure: a regime distinct from ancillary cumulative activity
Cultivating a few family hectares as an ancillary activity and establishing an EARL or a GAEC do not fall under the same rules. As soon as the agricultural project involves the creation or takeover of a business, another system applies: part-time for business creation or takeover.
This mechanism allows the agent to reduce their working hours to develop their project for a limited time. It requires a formal request and the opinion of the ethics commission (now linked, for certain categories, to the High Authority for Transparency in Public Life). The examination focuses on ethical aspects, with heightened vigilance regarding the risks of illegal interests.
A frequently underestimated point: the simple registration of an agricultural structure can trigger the obligation to resort to this regime, even without actual production. Creating the company first and regularizing later exposes the agent to disciplinary action for irregular cumulative activity. The texts stipulate that the prohibition of cumulative activity applies from the legal creation of the structure, not from the actual start of the activity.
Part-time civil servant and agricultural operation: what real margins
Agents holding a part-time position of 70% or less have a more flexible framework. They can engage in a lucrative private activity, provided they inform their hierarchical authority.
Beyond this threshold, or for full-time agents, the margin decreases. Agricultural activity must remain ancillary, which concretely implies that it does not engage the agent in a manner incompatible with their service hours.

The texts do not set any numerical threshold to define the ancillary nature. The assessment is made on a case-by-case basis: size of the operation, time devoted, income generated. This absence of objective criteria leaves a zone of uncertainty that administrative jurisprudence is gradually clarifying through disputes concerning very varied situations (a few beehives, a family sheep farm, an inherited grain operation).
Disciplinary risks in case of undeclared cumulative activity
Engaging in cumulative activity without authorization or declaration constitutes a breach of ethical obligations. Sanctions range from a warning to dismissal, depending on the severity and duration of the breach. The repayment of sums received for the unauthorized activity may also be required.
The texts governing cumulative activity do not distinguish between activity actually exercised and simple ownership of a registered structure without authorization. The absence of actual production does not constitute a mitigating circumstance as long as registration exists.
This framework applies equally to the three branches of public service (State, territorial, hospital). The observed disparities in treatment are less due to the applicable law, which is common, than to local practices in processing requests.
Before planting the first fence post or signing a rural lease, the sequence remains the same: precisely describe the project, request written authorization, wait for the response, and only then engage in the registration process. In that order.
