I have written about the Congressional Review Act before, so I will not repeat myself. Long story short, Congress will have the opportunity to review regulations promulgated by agencies late in the term of President Obama. This potentially matters a great deal. (Here is a link to Frequently Asked Questions about the CRA.)
How the CRA will work this time around is now coming into greater focus. Last week, the Congressional Research Service issued a memo listing all the major rules potentially subject to the CRA. And today, Professor Josh Blackman has a post that focuses on the date of particular regulations. (The date matters, for reasons he explains.) I suspect that many congressional staffers on both sides of the aisle will be paying close attention to the calendar.
