Get a copy of the code/law and highlight the points
That simply will not work. You cannot prove a negative. In other words, you cannot prove that something doesn't exist. Not having evidence of the "something" only shows that you don't have evidence.
So showing one law that matches your version law can lead to a claim that there is another law somewhere which matches his. And your argument is not won.
Unless you work together to examine every single law at all levels of government. And that is another definition of "impossible".
In conclusion, I would like to congratulate the OP on his interest in FALs
