Juries are a component of common law (and not used in all common law countries at that), and the vast majority of the world runs on the civil law system (which is, IMHO, better).
France has juries for 'crime' trials under the civil law system. I'm not sure the presence of juries can tell you which of the system you have, nor the system you have tell you whether you have a jury.
Lebanon has a lot of french influence so I thought it might be possible, not being myself familiar with the Lebanese system.
Ha, my mistake, i thought it's an exclusively common law thing.
> In France, a defendant is entitled to a jury trial only when prosecuted for a felony (crime in French). Crimes encompass all offenses that carry a penalty of at least 10 years' imprisonment (for natural persons) or a fine of €75,000 (for legal persons). The only court that tries by jury is the cour d'assises, in which three professional judges sit together with six or nine jurors (on appeal). Conviction requires a two-thirds majority (four or six votes).
