>To the best of my knowledge, this is the first contest I have ever heard of the makes a distinction of not including Quebec in a contest that includes Canada. Also, it may be interseting to note that if it is due to a difference of English law vs. French law, why wasn't the state of Louisiana excluded. A lot of their state laws are based on the French judicial system as well.
A lot of things is difficult to understand in that contest. As for US, since there is only one national official language, which is English, this is why it does not represent a problem. In Canada, we have two official languages. By including Canada, contest documentation need to be available in full in English and in French, either Quebec included or not. And, there is also other factors involved. I will try to explain more later.
