Due to the cost and risk involved, few cases go to jury trial... BUT if it's anything like the US a jury technically could consider things like this and refuse to render a guilty verdict.
In France, if I recall, isn't it usually a panel of judges? I don't think they use a jury.
Quick perusal indicates Cour d'assises is the only court with a jury analog, and it only deals with matters where the penalty would result in a >10 year sentence if I'm reading it correctly.
