The same problem has to be solved in countries with more than one official language. In Ireland, the Irish-language version of a law takes precedence. This is a little awkward in theory since parliamentarians, civil servants, judges and lawyers overwhelmingly do not speak Irish to a sufficient level to draft, debate or interpret the law, and laws often exist for years before anyone gets around to translating them and thereby creating the "definitive version". But in practice, the legal system generally works.
