France's Constitutional Council has invalidated the most contentious provision of the Loi Duplomb, which sought to reintroduce acetamiprid, a banned neonicotinoid pesticide. The court ruled this provision contrary to the Environmental Charter, effectively upholding the pesticide's ban in France despite its authorization in Europe until 2033. The decision has sparked division among agricultural unions and political factions, with some agricultural groups and right-wing politicians decrying it as detrimental to French farmers and others, including environmentalists and the left, welcoming it as a victory for health and environmental protection. Laurent Duplomb, the law's author and a senator from the Les Républicains party, expressed regret over the ruling and did not rule out proposing new legislation to reintroduce acetamiprid. The French government, led by President Emmanuel Macron, promulgated the Loi Duplomb without the contested pesticide provision. Macron's administration and the Prime Minister noted the absence of sufficient scientific or medical studies justifying the pesticide's reintroduction during the legislative debate. The ruling has raised concerns about unfair competition for French agricultural sectors, notably sugar beet and hazelnut producers, who had advocated for acetamiprid's return. The debate continues as some political figures call for further parliamentary deliberations, while environmental advocates emphasize the importance of the court's decision for public health and environmental safety.
