Now I have proof positive you have not read the law as the aforementioned "Article 8" is in fact a quote from AZ SB 1070!
"this" Article 8 is the Arizona statutes covering the "Enforcement of Immigration Laws," so to state that their new state law violates it when it is in fact adding this article to Title 11, Chapter 7 of the Arizona Revised Statutes makes your statement completely meaningless in that you are saying a law is violating itself.
Aside from the fact that you claim Arizona law will be ruled unconstitutional by violating itself, which is technically, if not logically, impossible. The further text quoted from that article under section B stated that the Federal government is the one doing the verification of the person's immigration status, and all references to immigration status and terms, specifically refer to various sections under 8 United States Code to determine their meaning and what is being enforced. So they cannot be violating Federal laws based on the fact that they are referring to those laws for what it is they are to be enforcing.
If you insist that this new immigration law allows their law enforcement agents to question anyone who appears suspicious or illegal, I challenge you to find where in SB1070 it even makes use of the word "question" and define what these "other things" among which their law enforcement officers are allowed to do.
