midnight rule making
n.— «Anticipating an end-of-administration rush to churn out hundreds of regulations—a practice known as “midnight rule making”—the White House counseled agencies to restrain themselves. “We need to continue [our] principled approach to regulation as we sprint to the finish, and resist the historical temptation of administrations to increase regulatory activity in their final months.”» —“Midnight rule-making bonanza” by Gregg Carlstrom Federal Times Nov. 2, 2008.
