Why are you acting as if this means that Brexit is now inevitably going to be blocked? Almost certainly it will not be. Instead, Parliament, whose power over the domestic law of this country is as near as dammit to absolute, will be given the say on whether and how it is implemented. Talking about lawyers running riot over the people is, furthermore, pretty stupid when you realise that one of the leading challengers of the government in this decision was a guy who voted FOR Brexit.
Sorry, but those who are concerned at the result, or horrified by it, simply haven't a leg to stand on. The referendum this year was advisory; it is now up to Parliament, and not the Crown, to act on that advice. Almost surely, they will and must do so, by which means we'll then be able to get on with it without worrying too strongly about future legal challenges. If anything, this should give Brexiters a sigh of relief.
