Olivier Bouygues, the French billionaire and brother of former Bouygues group CEO Martin Bouygues, appeared in court in Orléans on Monday to face charges of illegal hunting, including of protected bird species, on his private estate near the Sologne Forest, about 150 kilometres south of Paris. The trial, expected to last two days, marks an unprecedented case in French judicial history.
Bouygues, 75, is accused alongside five others of running a hunting operation that allegedly violated environmental laws for years. The charges carry a potential prison sentence of up to seven years and a fine of €750,000 if convicted. Five of the six defendants were present in court on Monday.
The case has drawn sharp criticism from conservation groups. Allain Bougrain-Dubourg, president of the League for the Protection of Birds (LPO), described the accused as “people who are rolling in money who exempt themselves from respecting biodiversity.” He told reporters that the trial should “serve as a warning” to France’s wealthy elite, who often believe they are above the law.
“Biodiversity is capable of suffering and the regulations are made for everyone, even those with great resources,” Bougrain-Dubourg added.
Evidence of systematic poaching
The investigation began after an anonymous tip led police to execute a search warrant on Bouygues’ Fontenaille estate in June last year. Officers discovered a mass grave containing the remains of protected birds, including great egrets, harriers, kestrels, great cormorants, and common buzzards. They also found prohibited items such as weapons and jaw traps, which have been outlawed in France since 1995.
According to the regional public prosecutor, investigators recovered a list of animal species—some of them protected—that were marked for elimination, along with evidence of previous killings. An excavator believed to have been used to dig graves for the hunted animals was also seized from the property.
The 600-hectare estate in Sologne, one of France’s largest forest areas and a popular retreat for the country’s wealthy, has been the focus of the investigation. The case has sparked debate about the impunity of the rich when it comes to environmental crimes.
Legal experts note that this is the first time a case of this nature has reached trial in France, making it a landmark for environmental enforcement. The outcome could set a precedent for how similar cases are handled in the future, particularly those involving high-profile individuals.
The trial comes amid broader European discussions about biodiversity protection and the enforcement of environmental laws. While the case is specific to France, it resonates across the continent, where illegal hunting and the trade in protected species remain persistent challenges. The European Union has been pushing for stricter penalties for environmental crimes, and this trial may serve as a test case for such measures.
Bouygues, whose net worth is estimated at around €3.2 billion, has not yet commented publicly on the charges. His legal team is expected to argue that the hunting activities were within the bounds of existing regulations, though the evidence gathered by police suggests otherwise.
The trial is being closely watched by environmental groups, who hope it will send a strong message that no one is above the law. As Bougrain-Dubourg put it, the case is about more than one individual—it is about the principle that biodiversity must be protected for everyone.
