This is a very important question, and it's a very interesting question. It's not an easy question to answer because linking human rights violations to the articles and details of a trade agreement is very difficult to do, which is why we at the Americas Policy Group worked with this committee over a period of a year or so to develop a recommendation for a human rights impact assessment to answer those very questions: how will the trade agreement affect the human rights in a particular country? In this case we were talking about Colombia.
A lot of research and academic work has been done, particularly by De Schutter.
