4.110—Prehearing briefs.
Based on an examination of the appeal file, the pleadings, and a determination of whether the arguments and authorities addressed to the issues are adequately set forth therein, the Board may, in its discretion, require the parties to submit prehearing briefs in any case in which a hearing has been elected pursuant to § 4.109. In the absence of a Board requirement therefore, either party may, in its discretion, and upon appropriate and sufficient notice to the other party, furnish a prehearing brief to the Board. In any case where a prehearing brief is submitted, it shall be furnished so as to be received by the Board at least 15 days prior to the date set for hearing, and a copy shall be furnished simultaneously to the other party.
