If an interlocutory appeal or
collateral attack is brought in any court concerning all or any part
of an adjudicatory proceeding, the challenged adjudicatory proceeding
will continue without regard to the pendency of that court proceeding.
No default or other failure to act as directed in the adjudicatory
proceeding within the times prescribed in this subpart will be excused
based on the pendency before any court of any interlocutory appeal
or collateral attack.
