In my opinion, the confusion lies in the fact that Konami is the maker of the Yugioh Card Game for both the English Territory as well as Asian, and establishes all "written" Official Rulings for said game.
Like anything else that is "one source", any questions are steered in their direction for clarification, which we have all seen, can take days, months, or years, and sometimes "never", to answer.
As the go between, UDE established the Judge List to intercede on Konami's behalf and also created the FAQ located on the Official Yugioh-Card.Com Website. While a Ruling from Konami is considered "final" until they decide it needs to be redressed, Rulings given by any entity other than Konami, in my opinion, is weighed against the Certification of the individual providing the Ruling.
While a Level 1 Judge can certainly be as Knowledgeable as a 2 or 3, the Knowledge is assumed to be commensurate with Level attained. As a acting representative for Konami/UDE, each Judge is tasked to give "expert opinions" in the absence of clear or concise Rulings, either based upon similar existing Rulings, or by defining the Card Text as clearly as possible.
This is as "Official" as it gets when not delivered directly from the hands of Konami. It is not feasible to expect to wait for a ruling to be given by Konami during a Tournament in progress. If a Judges Ruling were not considered to be "Official", then the continuance of even the most basic Sanctioned Tourney would be unable to continue. Right or Wrong, a Ruling is Oficial when delivered by a Certified Source.
When we question a Ruling given by the Judge List, surely it is reasonable to believe that it could be incorrect. It is also reasonable to believe that a Ruling from Konami could ALSO be incorrect. So, what is it that makes one Source more credible than the other? Is it the fact that one comes from the Original Source of the Game, while the other comes from the attainment of required Level Certifications?
Again, I would say that there is a Heirarchy established with Rulings, which is no different that a Tourney Atmosphere. Floor Judges can be overruled by the Head Judge. The Judge List can be overruled by Konami. Nevertheless, from the Floor Judge all the way to Konami, a Ruling is Official unless it is contradicted by a higher source with the ability to do so.
Just my opinion....
