On August 7, 2025, France's Conseil constitutionnel invalidated the most contested provision of the Loi Duplomb, which sought to reintroduce acetamiprid, a banned neonicotinoid pesticide. The court ruled that this provision was contrary to the French Environmental Charter. The decision sparked divided reactions: left-wing parties and environmental groups hailed it as a victory for health and the environment, while agricultural unions such as the FNSEA and right-wing politicians condemned it as unacceptable and harmful to farmers. Laurent Duplomb, the law's author and a senator from the Les Républicains party, expressed disappointment and criticized the ruling for creating unfair competition for French agricultural sectors. He did not rule out proposing new legislation to reintroduce acetamiprid. The pesticide is currently authorized in Europe until 2033 but remains banned in France. Producers of sugar beets and hazelnuts, who had advocated for the pesticide's return, voiced concerns about the impact on their industries, warning of potential risks to certain agricultural sectors. The French Minister of Agriculture highlighted the risk of disappearance of some farming sectors following the court's decision, while the Minister of Health called for a European reassessment of acetamiprid's health impact. The ruling has intensified the debate over pesticide use in France, with calls from some local officials for a second parliamentary deliberation on the law. The controversy also echoes wider European concerns about pesticide safety and environmental protection.
