Legal commentators have long speculated that Supreme Court Justices prefer to release their most controversial opinions at the end of each term before embarking on summer recess to travel, teach, and write.

For the fifth straight term, however, the Court has more than half of its opinions still outstanding at this point of the year.  The Court completed its scheduled oral arguments on April 24, yet 40 of the Court’s expected 69 opinions will be released between now and the term’s conclusion on June 24.

One of the most consequential cases of the term, Department of Commerce v. New York, concerns whether the Trump Administration can add a citizenship question to the 2020 census. Court watchers expect the opinion to be released in the last week of June.

recent study by Lee Epstein of Washington University, William Landes of the University of Chicago, and Judge Richard Posner analyzed 7,219 cases from 1946 to 2013 to determine the truth, if any, to the so-called “end-of-term-crunch.”

The trio discovered that on average more than 30 percent of cases are issued in June – and more than half of those are issued in the week preceding summer recess.

Of note:

24.2 percent of all cases decided in the last week of June made the front page of the New York Times, compared to only 15.3 percent for cases decided earlier in June and 11.3 percent for cases decided in all other months combined.

An average of 5.2 amicus curiae briefs were filed per case for cases decided in the last week of June, 3.1 for cases decided earlier in June, and 2.5 for cases decided in other months.

As Adam Liptak of the New York Times pointed out, “In 2013, for instance, the three final days of the term felt like the judicial equivalent of sweeps week on network television.  Monday: affirmative action. Tuesday: voting rights. Wednesday: gay rights.”

The last week of 2014 was just as compelling with 5-4 rulings on contraceptive coverage and abortion protests.

Liptak summarized three possible reasons for waiting so long to decide a term’s biggest cases.

One is that justices keep polishing the opinions that will define their legacies until the last possible moment.

A second possibility is that releasing several major decisions in quick succession, some liberal and some conservative, may tend to diffuse media coverage and other commentary of any particular case, and thus spare the justices unwanted criticism.


[third] perhaps the explanation is more personal: The justices, most of whom have busy social schedules in Washington, may want to avoid tensions at their social functions by clustering the most controversial cases in the last week or two of the term – that is, just before they leave Washington for their summer recess.

While Justices and former Supreme Court law clerks maintain that opinions are released as soon as they are ready, the self-imposed deadline ensures that the final weeks in each term are pressure packed and anxiety ridden.
