After years of fraught debate, France moved to the brink of legalizing medically assisted dying. The National Assembly, the lower house of parliament, was expected to give final approval on Wednesday to a bill that would let certain gravely ill adults receive lethal medication, a measure President Emmanuel Macron first proposed more than three years ago.

How it would work

The law creates a tightly bounded path. It would apply to adults with a serious, incurable illness at an advanced or terminal stage who are judged mentally competent and give free, informed consent, with medical review and a reflection period built into the process. Patients would generally administer the medication themselves; a doctor or nurse could assist only when a patient is physically unable to do so. Psychological suffering alone would not qualify a person, and people with psychiatric conditions or neurodegenerative diseases such as Alzheimer's would be excluded, distinctions that make the French measure narrower than the laws of some neighbors.

A contested path through parliament

The bill's route has been unusual. The National Assembly backed it in earlier readings, but the Senate, the upper chamber, rejected it. Under France's constitution, the government allowed the Assembly to have the final say without the Senate's assent. Even so, adoption will not be the end of the road: Prime Minister Sébastien Lecornu has said he will refer the law to the Constitutional Council, France's highest constitutional authority, for review.

The debate

Supporters frame the law as a matter of dignity and personal autonomy for people facing unbearable suffering at the end of life, and point to its safeguards and medical checks. Opponents come from several directions. Disability-rights advocates warn that the option could put subtle pressure on elderly, ill or disabled people; religious groups have organized protests; some doctors have raised ethical objections; and parts of the political right, including the far-right National Rally and conservatives who dominate the Senate, have argued the text is dangerous and open to abuse.

Where France would stand

If adopted, France would join a small group of countries, among them the Netherlands, Belgium, Switzerland and Canada, that permit some form of assisted dying, though its version would remain comparatively restrictive. For a country that has debated the question for decades, the vote marks a profound shift in how the law treats the end of life, and, given the Constitutional Council review still to come, not necessarily the final word.
