They do have coercive legislation of a form. It's called the About-Picard law. It's a very broad criminalization of coercive control that's not specific to intimate partner violence. It covers any type of coercion, so it's also been used in cases of cults and religiously coercive groups.
The discussions in France are to expand the law or to enhance their law specifically to lay it over intimate partner violence, but they already have that law. I think they just want to enhance it in order to make it more specific to intimate partner violence.
