The law of bioethics defines the judicial framework for governing medical practices and research involving the human body and the embryo. Does any scientific or technologic innovation warrant a modification of the law? To respond to this question, a preliminary reflection is necessary so as to define new equilibria which respect ethical principles, the promotion of solidarity with respect for the autonomy of each person.The CCNE is charged with organizing public debate, in the form of a general assembly of bioethics, with the support of regional spaces of ethical reflection. This extensive experience took place from January to June 2018 and lead to several lessons, notably the strong expression of a need for information and a critical vision of the notion of medical progress.Then, the parliamentary instruction and hearings that accompanied it, from 24 July 2019 to 2 August 2021, contributed developments to the initial bill. Thus, the periodic review of the law of bioethics is now based on citizen participation in the construction of legislative arbitration, demonstrating the French way of social participation.
