The French Senate opened debate Tuesday on legislation that would impose joint financial liability on individuals who join groups responsible for vandalism and violence, requiring them to help cover damages up to 10,000 euros each.

The so-called "casseurs-payeurs" bill, advanced after weeks of unrest including looting and arson tied to October 17 demonstrations, aims to shift costs away from taxpayers and toward those involved in collective disorder. Under the proposal, anyone who knowingly remains in a gathering after police dispersal orders could face civil responsibility for harm caused by others in the group, even without direct proof of personal involvement in specific acts.

Government officials argue the measure addresses a practical gap in existing law, where identifying individual perpetrators in chaotic scenes has proven difficult. It also permits seizure of certain social benefits, such as family allowances and housing aid, to enforce payment, with parents potentially liable for minors. An amendment under consideration would expand authorities' ability to pressure social media platforms to remove content inciting violence.

Recent events have intensified pressure for action. Violence following Paris Saint-Germain's Champions League win last May and more recent nationwide protests have left businesses and public property damaged, with taxpayers often covering repairs through insurance or state funds. Supporters, including voices from the right and center, view the bill as a commonsense step to deter lawlessness and restore order.

Critics on the left and from rights organizations contend the language risks ensnaring peaceful protesters and could chill legitimate assembly. They point to the joint liability provision as overly broad. The Senate's law commission already strengthened some elements of the text earlier this month before full chamber consideration.

If enacted, the law would apply to damages from group violence in public spaces, benefiting victims, insurers, and the state. Debate is scheduled to continue into Wednesday, with passage appearing likely given the Senate's composition. The measure reflects broader efforts to respond to recurring episodes of urban disorder without relying solely on criminal penalties.
