This article is more than just interesting. It states that only those contracts that include a clause about submitting disputes to arbitration are eligible for the type of dispute settlement mechanism that we have initiated. The MOC does not contain such a clause. I don't know if this applies to the Can-VZ BIT or not but I'd sure like to get a definitive statement from a competent authority.
If we can't use the BIT then VZ is very likely to just brush us off. At the very least we would see a delay due to a juristictional challenge. Hopefully the BIT covers all investments made in VZ not only those that have an arbitration clause.
