(a) Default: If any party has failed to plead or otherwise proceed as provided by these Rules or as required by the Court, then such party may be held in default by the Court either on motion of another party or on the initiative of the Court. Thereafter, the Court may enter a decision against the defaulting party, upon such terms and conditions as the Court may deem proper, or may impose such sanctions (see, e.g., Rule 104) as the Court may deem appropriate. The Court may, in its discretion, conduct hearings to ascertain whether a default has been committed, to determine the decision to be entered or the sanctions to be imposed, or to ascertain the truth of any matter.

(b) Dismissal: For failure of a petitioner properly to prosecute or to comply with these Rules or any order of the Court or for other cause which the Court deems sufficient, the Court may dismiss a case at any time and enter a decision against the petitioner. The Court may, for similar reasons, decide against any party any issue as to which such party has the burden of proof, and such decision shall be treated as a dismissal for purposes of paragraphs (c) and (d) of this Rule.

(c) Setting Aside Default or Dismissal: For reasons deemed sufficient by the Court and upon motion expeditiously made, the Court may set aside a default or dismissal or the decision rendered thereon.

(d) Effect of Decision on Default or Dismissal: A decision rendered upon a default or in consequence of a dismissal, other than a dismissal for lack of jurisdiction, shall operate as an adjudication on the merits.
