I don't see how you can make such a binary claim - UK vs "the rest of Europe". Your map shows 6 broad categories of legal systems in use across Europe. Even if you put the 5 non-common law systems into one bucket, it still wouldn't make the UK unique as Ireland operates under common law.

You are right, it is not binary in the way I wrote. I guess one difference between UK and Ireland is absence of a written constitution?
