I think it's a very good example of the way that you can't rely on laws to stay the same. You can't say it's okay that we have a bad law, because the person in charge is not going to do anything wrong with it. We need to be cautious, to make sure that what we have here says what we mean it to say and to make sure that it provides the protection that we want to provide.
The examples we have in the States, where laws are essentially being made by executive order, are very good examples of the way that the rule of law is at risk if we don't have strong, effective, and not vague laws in the first place, which are harder to challenge.
