(a) If a defendant does not file any answer within 30 days after service of the complaint, the reviewing official will refer the complaint to the ALJ.

(b) Once the complaint is referred, the ALJ will promptly serve on the defendant a notice that an initial decision will be issued.

(c) The ALJ will assume the facts alleged in the complaint to be true and, if such facts establish liability under the statute, the ALJ will issue an initial decision imposing the maximum amount of penalties and assessments allowed under the statute.

(d) Except as otherwise provided in this section, when a defendant fails to file a timely answer, the defendant waives any right to further review of the penalties and assessments imposed in the initial decision.

(e) The initial decision becomes final 30 days after it is issued.

(f) If, at any time before an initial decision becomes final, a defendant files a motion with the ALJ asking that the case be reopened and describing the extraordinary circumstances that prevented the defendant from filing an answer, the initial decision will be stayed until the ALJ makes a decision on the motion. The reviewing official may respond to the motion.

(g) If, in his motion to reopen, a defendant demonstrates extraordinary circumstances excusing his failure to file a timely answer, the ALJ will withdraw the initial decision, and grant the defendant an opportunity to answer the complaint.

(h) A decision by the ALJ to deny a defendant's motion to reopen a case is not subject to review or reconsideration.
