We have it because it is just possible that the courts could find a way in. We have seen them getting involved in areas that we never thought they would get involved in before. That is a fact of the way the judiciary has moved in recent years, and it is why the clause is there.
I do not accept that the clause sets a dangerous precedent. It is about this one very narrow issue. It is not about an ouster clause that would be put in every statute that came before Parliament. Of course, Parliament must decide at the end of the day how it wants to frame its laws. It has the right to do that, and the courts can then interpret those laws, but I do not believe that this will be seen as a precedent for a more general use of ouster clauses. If it is, I am fairly sure that Parliament would not accept them. We should see this clause in the narrow concept in which it is drafted and not try to extend it beyond that.
