All conflicting information discovered during the development process must be resolved
            before final adjudication. The Adjudicator is responsible for researching and developing
            all information needed to record formal or informal special determination.
         
         Formal determinations are required to cite authority in the Act or regulations along
            with details of facts that lead to the conclusion, while an informal determination
            can be less structured, handwritten, and with no citation of authority. However, both
            determinations are required to provide sufficient information to justify each conclusion.
