There is no law that isn't open to interpretation. There is a reason for the judicial branch of government.
The understanding is that interpreting laws leads to bias, partiality, and injustice; while following the letter of the law equally in each situation is the most just approach.
I lived in Lithuania for a while and at the time, there was a big national debate about how “family” should be defined in laws — what people it can and can’t include.
So yes — a lot of emphasis is put on verbose definitions in literalist legal texts. And very very verbose explanations of many edge cases, too,
I know first hand it will be very hard to read Lithuanian legal texts for someone who is not a native speaker of the language, and even for natives it’s a challenge. So you could instead google “literalist legal systems”, and I believe you’ll find at least some examples/more context in English somewhere.
