It's a similar objection sometimes to the Reserve Bank bill. It doesn't involve Reserve Bank independence; it involves Reserve Bank transparency. In a very similar way, this simply requires the publication of a certificate showing that the lawmaker has at least attempted to follow the principles of good lawmaking, and for failing to either publish or actually follow the principles, they can face a declaration from the courts that they have failed to make laws in accordance with good principles. That doesn't invalidate the law.
