Proposition seven is the first stage of analysis is whether triggering Article 50 will dispense with laws. That is the overarching principle. Proposition eight, if triggering Article 50 will dispense with one or more laws, that is the end of the matter; the question of abrogation simply does not arise. Why doesn't it arise? Because there is no relevant prerogative or use of prerogative for it to arise. Nothing is being abrogated. The abrogation has started with the immediate bar to a prerogative power ever being used, capable of being used to dispense with laws.
