Failures to act other than the defaults listed in § 210.16 may provide a basis for the presiding administrative law judge or the Commission to draw adverse inferences and to issue findings of fact, conclusions of law, determinations (including a determination on violation of section 337 of the Tariff Act of 1930), and orders that are adverse to the party who fails to act. Such failures include, but are not limited to:
(f) Failure to respond to a petition for review of an initial determination, a petition for reconsideration of an initial determination, or an application for interlocutory review of an administrative law judge's order; and
(h)Default by notice. If a respondent has filed a response to the complaint or notice of investigation under § 210.13 of this chapter, the respondent may still file a notice of intent to default with the presiding administrative law judge at any time before the filing of the final initial determination. The administrative law judge shall issue an initial determination finding the respondent in default upon the filing of a notice of intent to default. Such default will be treated in the same manner as any other failure to act under this section. The filing of a notice of intent to default does not require the administrative law judge to issue an order to show cause as to why the respondent should not be found in default.
