Article II, Section 3 of the US Constitution:
The bolded part of this section gives the President the power to convene or adjourn Congress. President Truman in 1948 was the last to force Congress into session, the first time since 1856. That power has been used 27 times in total and seems to be relatively noncontroversial and practically unnecessary with the way Congress works now.
My question has to do with the power of the President to adjourn Congress. From what I've gathered, this power has never been exercised. In term of recess appointments, this power looks to be one that gives the President a way to exercise that power, provided his party has at least one House of Congress. According to the majority opinion in NLRB v. Noel Canning:
All this would take would be either the House or the Senate passing an adjournment resolution where the other did not. In this case, the President merely needs to have his party control either the House or the Senate. That body would pass an adjournment resolution. If the other House chooses another date or doesn't take up the resolution at all, a disagreement would have arisen. The President could therefore force Congress to adjourn. For the sake of recess appointments, he would adjourn Congress for at least 10 days so that he could make said appointments.
It seems like so long as the President has at least one House willing to go along with this, there is no way to stop him. (Obviously, this is basically a moot point either way if one party controls both Houses of Congress.) However, rather significantly, this would seem to allow the President to thwart an opposition Senate if he controlled the House. (For some reason, a President controlling the House but not the Senate is exceedingly rare. It happened during the first two years of the Bush Administration when Jeffords switched. Before that, you have to go back to the 19th century).
Looking at this power overall, when there's a disagreement between the Houses of Congress, the power seems to extend to no later than the rest of the year, as Congress is required to meet on January 3rd of every year (unless a law is passed to change the date). If the requisite circumstances were met, the President could theoretically adjourn Congress for the rest of the year.
I realize a lot of this is theoretical and could easily spark a constitutional crisis, but am I wrong? What does everyone else think?
