I quoted you verbatim. You said they are "the same law."
A law that says "all cardinals vote" is NOT "the same law" as the law that says "cardinals over 80 may not vote."
You might as well argue that "black" and "not black" are the same color.
Your problem is that you are not differentiating. The law for voting *is* the same law and applies only to those within the conclave. This is indisputable so please, no sense arguing this point any further.
The law of who can and cannot vote in the conclave is not the same. PPVI changed the requirement to only those under 80 years old can vote.
I agree that this new law is stupid and wholly disagree with it, although any more I don't think it matters much, and having achieved it's purpose, in a few more years I don't think it will matter at all, but that those over 80 cannot vote does not effect the validity of those voting, or the election in any way. All it does is slightly reduce the number of voters, which, although it's possible that this law might possibly affect the outcome of the elction, it does not affect the validity of the election. I don't know why this bit of reality eludes you.
As an aside, the conclave had to cast their ballots 5 different times before they finally elected Francis as pope, so much for the allegation of lobbying.Now, which law is it that applies to me, but not to you?
What do you hope to gain by arguing against the law?
