What do you call a country where the legal system is observed? I came up with a "nomocratic country", but that seems to be used extremely rarely. There is a Wikipedia page talking about the Rule of Law, but I cannot come up with a way how to twist it into an adjective (or adjective phrase, if there is such a thing) to describe a country.
The context
I found a sentence somewhere which reads "Since Czech republic is a modern legal country based on a democratical regime, there are fundamental human rights being guaranteed." and I am trying to figure out how to rewrite it. I got stuck with the "legal country". It is obviously wrong, but I cannot figure out what's better to say.
