Marc-Yvan Cote back in?

I'm not sure I understand this at all. I don't know the story behind the story, and if Marc-Yvan Côté is an innocent and a fall guy then so be it. But if he isn't... "exaggerated" punishment? A life-long ban from holding a membership in the party? Believe it or not, people can go on to live fairly normal lives without pulling the odd Marie-P. Poulin email out of their junk folders. This isn't Buzz Hargrove - Côté hurt the party dramatically by acting exceptionally unethically. What do you have to do to earn a ban from the party? Why even unearth the issue now? This is very strange to me.
