A church judgment is one that comes from the body of the hierarchy, which makes a decision using known and established procedures from canon law. It doesn't come from 2 cardinals, or 15 bishops, or 4,000 priests. It is a decision by the Church as a whole and it must be followed by all. Until that happens, it's not an official decision. Doesn't mean that it's the wrong decision, it just means it's not official.
I don't want to get off on a tangent about V2, but those errors which are rejected are pretty easy to reject, considering they contradict previously defined and infallible doctrines. There are other reasons too, but really, this is off topic.
