4.127—Dismissals.
(a) Dismissal without prejudice.
In certain cases, appeals docketed before the Board are required to be placed in a suspense status and the Board is unable to proceed with the disposition thereof for reasons not within the control of the Board. Where the suspension has continued, or may continue, for an inordinate length of time, the board may, in its discretion, dismiss such an appeal from the docket without prejudice to its reinstatement when the cause of suspension has been removed. Unless either party or the Board acts within 3 years to reinstate any appeal dismissed without prejudice, the dismissal shall be deemed to have been made with prejudice.
(b) Dismissal for failure to prosecute or defend.
Whenever a record discloses the failure of either party to file documents required by these rules, respond to notices or correspondence from the Board, comply with orders of the Board, or otherwise indicates an intention not to continue the prosecution or defense of an appeal, the Board may issue an order requiring the offending party to show cause why the appeal should not be either dismissed or granted, as appropriate. If no cause is shown, the Board may take appropriate action.
