With yesterday’s rulings, the Supreme Court has now disposed of 38 of the 70 cases on this term’s argument calendar. I’m relying on the tables in this report prepared and maintained by attorneys at Mayer, Brown, Rowe & Maw. (The current version of the report is from late April; my calculation adds in the May rulings.) The Court’s term is expected to conclude the week of June 23, so nearly half the Court’s rulings for the term will be rendered over the next five weeks.

Because opinion assignments are roughly even for each argument session, the month-by-month tables in the Mayer, Brown report sometimes enable intelligent guesswork as to who will be writing the majority opinions in remaining cases. For example, only one case (or, more precisely, one pair of consolidated cases) remains from the December argument session—the much-watched Boumediene v. Bush (and Al Odah v. United States) concerning the Military Commission Act of 2006 and Guantanamo detainees—and only Justices Kennedy and Souter have yet to write lead opinions for that session. Because Kennedy is likely the swing vote in that case, because Souter was the only justice to write two lead opinions in the preceding session, and because it’s difficult to imagine either the Chief Justice or Justice Stevens assigning Boumediene to Souter, it’s highly likely that Justice Kennedy is writing the opinion in Boumediene.

Non-argument sessions at which rulings may be announced are scheduled for next Tuesday (the day after Memorial Day) and each of the first four Mondays in June. The Court typically announces some additional sessions in mid- or late June. On the days on which ruling are announced, SCOTUSblog is usually quickest to give the bottom line and to provide links to the opinions.
