It's always a question about what might have an impact.
I think it's important for governments and parliaments around the world to uphold principles and, for example, rulings of the Inter-American Court of Human Rights, although I would add that it's a bit awkward for both Canada and the United States to press on that issue, since they are not members of that court. That's a bit of a problem for both of our countries in terms of using that avenue, but through our group, the Friends of the Inter-American Democratic Charter, we have certainly tried to uphold that ruling.
I think standing up for principles is important, and certainly the UN's special rapporteur made a lot of statements in favour of Judge Afiuni or about the lack of due process there. I think following along those lines is fine.
Impact, I think, is a different question. I think private communications can sometimes be helpful as well, and that depends on relationships and whether there's a basis for private communications.
Other than that, I'm not sure what further involvement there could be. Issuing statements is really about as much as anyone can do in this situation.
