We can believe a lot of things that are untrue. He may have believed that his marriage was valid but obviously examination by a competent Tribunal revealed otherwise.I do not believe God gave fallible tribunals the confessional authority you seem to credit it with.
If you firmly believe you were validly married before then you may not marry again even if a tribunal comes to that decision. The new one may be a valid marriage technically but you would be violating your own conscience and so malicing God. This is basic moral theology.
