Everything you want the Board to know about the case should be included in your submissions. This includes the evidence such as documents, reports, diagrams, letters of support, etc. In addition, affidavit evidence or written statements from witnesses may be included. Participants should not assume that someone else will provide the information or evidence to the Board, or that the Board will already know something. The Board gets its information in the appeal directly from the participants and does not make inquiries into the facts of the appeal outside of that process.
