This will lead to court cases, and those court cases will lead to using those treaties as a base. All it takes is for a Judge to think "Naaa...that's silly" and then make a judgement. Now that becomes precedence.
It is more complicated than that, as this is an international treaty, not a national law. A violation of treaty isn't just a court case - it is an international incident, possibly considered an act of war.
The normal process of how implementation of law goes and is modified within a country does not generally apply to international treaties.
