The answer was literally, well, this country was formerly part a French colony and part an English colony; some of the judges were trained in French civil law and some of the judges were trained in English common law; the French civil law doesn't really recognize aircraft leases while the English common law does, and it depends on who you get.
On nous a répondu, littéralement, que le pays avait jadis été une colonie française et anglaise, et que certains juges étaient spécialisés en droit civil français, et d'autres, en common law britannique.
