European Union (Withdrawal) Bill

It is my understanding that the Minister is saying that courts that were told that Ministers had two options, both of which might be necessary solutions to a particular problem, would therefore say that neither passed the necessity test because Ministers had chosen between the two of them. That sounds utterly ludicrous as a way in which the courts would make a decision. Will the Minister elaborate by providing a case law example of a situation where the courts have been given such a necessity test and have decided to rip up all necessary options on the basis that there were too many necessary choices?
