In the case of any deadline for, relating to, or involving any rule which does not take effect (or the effectiveness of which is terminated) because of enactment of a joint resolution under section 802, that deadline is extended until the date 1 year after the date of enactment of the joint resolution. Nothing in this subsection shall be construed to affect a deadline merely by reason of the postponement of a rule’s effective date under section 801(a).

The term “deadline” means any date certain for fulfilling any obligation or exercising any authority established by or under any Federal statute or regulation, or by or under any court order implementing any Federal statute or regulation.
