WTO Trade disputes "from the inside"

This will be an interesting talk:

Appellate Body Member Tom Graham will be giving a talk at Hofstra on Feb. 6 entitled "It Sure Looks Different From the Inside: Deciding International Trade Disputes at the WTO". The title sounds promising, and from what I understand he will talk a bit about the use of the Vienna Convention by the AB in its decision-making.  He is not likely to be as forthcoming as, say, Justice Scalia, but he may say some interesting things nonetheless.

I don't see anything about live feed, too bad. I would have like to hear what he had to say--WTO decision-making is of interest to those of us keeping an eye on arbitration in tax treaties.
