In programming terms: namespacing. You have a set of activities which people do. You have validations on those activities. To determine whether a working arrangement is legal, all validations must pass. The UK has one set of validations. The EU has another. Some of them check the same things. Both the EU and UK validations make use of abstractions. One of these abstractions they reference is a particular symbol named 'work'. However, the symbol for 'work' is not defined in a common namespace or dictionary, but is instead private to each ruleset. Therefore if the EU court rules that 'work' must be defined a certain way for the purposes of EU regulations, it does not affect the UK regulations. If you think that's at all confusing wait until you hear about the government of the city of London. http://www.youtube.com/watch?v=z1ROpIKZe-c http://www.youtube.com/watch?v=z1ROpIKZe-c
