Reference Decision: cc • No. 86-10.423 • 1988-06-22 • View decision →
You own a company in Sainte-Foy-lès-Lyon and have just moved your head office to Strasbourg? Or perhaps you are a manager of a company in Oullins, wondering about the amount of your workplace accident contributions? A question nags at you: why do some companies benefit from a reduced rate and others not?
This decision of the Court of Cassation of 22 June 1988 answers a precise question: can a ministerial order exclude from the reduced rate companies whose business is registered with an URSSAF within the district of the Strasbourg regional fund? The answer is yes, and it is not illegal under Article L.132 of the Social Security Code.
In plain terms? If you have your head office or offices in this area, you cannot claim the benefit of a special pricing that is only provided for by order, not by law. Let's dissect this decision, which, although dating from 1988, remains relevant for the companies concerned.
The facts: a story like many others
Mr. X, director of a public works company based in Sainte-Foy-lès-Lyon, had transferred his head office to Strasbourg for tax reasons. However, his main activity remained in the Lyon region, with sites in Oullins and surrounding areas. When calculating his workplace accident contributions for the year 1984, the Strasbourg regional health insurance fund applied a single rate for all his staff, refusing the reduced rate enjoyed by office employees in other regions.
Mr. X contested this decision before the friendly settlement commission, then before the social security tribunal. His argument? The order of 22 December 1983, which excluded the application of the reduced rate to companies with a business registered with an URSSAF within the Strasbourg district, was illegal because it was contrary to Article L.132 of the Social Security Code (old), which provided for pricing based on risks.
The Colmar Court of Appeal dismissed his appeal, and Mr. X appealed to the Court of Cassation. The High Court upheld the judgment, holding that the special pricing for head offices or offices was not provided for in Article L.132 at all, but resulted from annual ministerial pricing orders, so illegality with regard to that article could not be invoked. The reduced rate was therefore not due.
The court's reasoning — dissected
The Court of Cassation relied on the special regime established in the Strasbourg district by the decrees of 14 March 1947 and 27 March 1953. This regime provides that all staff of an establishment or company are subject to the same rate, with the reduced risks of administrative staff lowering the rate applicable to technical staff when calculating.
In concrete terms, in this area, office employees (low risk) are not separated from workers (high risk). A single rate is calculated for the whole company, averaging the risks. The result: companies with many workers pay a lower rate than in other regions, but those with a majority of office employees pay a higher rate. This is an internal equalisation.
Article L.132 of the Social Security Code (old) laid down the principle of risk pricing, but did not impose a reduced rate for head offices alone. Annual ministerial orders may therefore provide for exceptions or special regimes, without being illegal. The Court simply recalled that the law does not guarantee an automatic reduced rate for offices: it is an advantage granted by order, and therefore removable by order.
This decision is neither a reversal nor an evolution: it confirms constant case law on the validity of pricing orders. The judges considered that the Strasbourg regime was lawful and that Mr. X could not complain about it.
What this changes for you — concretely
For company owners with their head office or offices in the district of the Strasbourg regional fund (which covers Bas-Rhin and Haut-Rhin), this decision means that you cannot claim a reduced rate for your administrative staff. You will be subject to a single rate for all your staff, regardless of where the activity is carried out.
Let's take a numerical example: a construction company in Oullins, employing 10 workers (average rate 4.5%) and 5 office employees (average rate 1.2%). Under the Strasbourg regime, the single rate would be (10×4.5% + 5×1.2%)/15 = 3.4%. In the Lyon region, office employees would have contributed at 1.2% and workers at 4.5%. The company therefore pays more for its offices, but less for its workers. On a payroll of €500,000, the annual difference can reach several thousand euros.
If you are an employee or self-employed, this does not directly affect your rights, but your employer may see its contributions increase, which can impact its financial health and, ultimately, your jobs.
For real estate professionals (agents, notaries), if you advise a company considering setting up in Strasbourg, be aware that the single pricing regime can be a hidden cost to factor into the budget.
Four tips to avoid this type of dispute
- Check your URSSAF district: Before contesting a contribution rate, make sure you know the regime applicable in your area. The map of regional funds is available on the Health Insurance website. If you are in Strasbourg, expect a single rate.
- Consult the annual orders: The reduced rate for offices is not an acquired right. Each year, a ministerial order sets the rules. Download it from Légifrance to check if your situation is concerned.
- Anticipate the cost: If you create a subsidiary or head office in Strasbourg, include the potential extra cost of the single rate in your business plan. Do a simulation with your accountant.
- Do not contest on the basis of Article L.132: As this decision shows, the argument of illegality of the order with regard to that article is doomed to fail. Look for other avenues, such as a calculation error or unjustified discrimination.

This decision is part of a line of Court of Cassation rulings from the 1980s validating special pricing regimes. For example, the decision of 14 June 1990 (no. 88-17.345) confirmed that the single rate could apply to all establishments of the same company located in the same district, even if some have different risks.
More recently, the Court of Cassation had occasion to clarify that the Strasbourg regime was not contrary to the principle of equality (Cass. 2nd Civ., 12 January 2012, no. 10-27.107). The judges consider that the difference in treatment is justified by local peculiarities.
The trend is therefore towards stability: the Strasbourg regime is well established, and it is unlikely to be overturned. For companies, the only possible evolution would be a modification of the ministerial order, which is a matter of regulatory power.
What you absolutely must remember
- Who is affected? Any company with a business registered with an URSSAF within the district of the Strasbourg regional fund (Bas-Rhin, Haut-Rhin).
- What is the risk? Not benefiting from the reduced rate for head offices or offices, and being subject to a single rate for all staff.
- What to do if you are already in dispute? Check whether your challenge is based on the illegality of the order with regard to Article L.132: if so, abandon that argument. Instead, look for a material error in the calculation of your rate.
- How to avoid? Find out before setting up, and perhaps negotiate with the URSSAF a staggered payment of contributions if the single rate penalises you heavily.
- What if you leave the district? Transferring your head office out of the Strasbourg area may allow you to exit the single regime, but beware of other tax and social implications.
