France's Constitutional Council has 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 among agricultural unions and political groups, with some viewing it as a victory for environmental and public health advocates, while others, including many farmers and right-wing politicians, condemned it as detrimental to French agriculture. Acetamiprid remains authorized in Europe until 2033 but is currently banned in France. The law's author, Senator Laurent Duplomb, has not ruled out proposing new legislation to reintroduce the pesticide. Following the court's ruling, President Emmanuel Macron promulgated the Loi Duplomb without the provision allowing acetamiprid's use. The move has prompted calls for further debate and reevaluation of the pesticide's health impacts at the European level. Agricultural sectors such as beet and hazelnut producers have expressed concern over the decision, fearing negative effects on their industries. The controversy continues to fuel political debate, with some urging the government to reconsider the law amid public petitions and ongoing discussions about alternatives to acetamiprid.
