France's Constitutional Council has invalidated key provisions of the recently passed Loi Duplomb that would have allowed the reintroduction of acetamiprid, a banned neonicotinoid pesticide. The decision came amid widespread public outcry and divided reactions from agricultural unions, political parties, and environmental groups. While the left and environmental activists hailed the ruling as a victory for public health and biodiversity, right-wing parties and some agricultural producers, including beet and hazelnut farmers, criticized it as detrimental to French agriculture and a risk to certain farming sectors. Laurent Duplomb, the law's author and a senator from the Les Républicains party, expressed disappointment and did not rule out proposing new legislation to reintroduce the pesticide. The French Prime Minister noted the lack of scientific or medical studies supporting the pesticide's reintroduction during legislative debates. Following the council's partial censure, President Emmanuel Macron promulgated the Loi Duplomb without the contested provision on August 12, 2025. The law's enactment maintains the ban on acetamiprid despite its authorization in Europe until 2033. The decision has sparked ongoing debate about France's agricultural policies, pesticide regulations, and the balance between environmental protection and farming interests. Calls for a European reevaluation of acetamiprid's health impact have emerged, alongside demands from some politicians for further parliamentary deliberations on the matter.
