Re: Can someone explain why they renumbered the articles?
I think you're right. From memory, several of the MEPs who voted for "17" and "15" were voting for the *old* 17 and 15, not the new ones. When they found out, they tried to withdraw their votes, but were told they couldn't.
I don't remember the exact numbers, but "several" would have actually swayed the vote in the other direction.
