The Supreme Court has 90 days from a case’s submission — typically, once a case is argued or reargued — to file its opinion. Also, the court almost always files its opinions on only Mondays and Thursdays.
The last regular filing day within the 90-day period for the seven cases argued on the March calendar is Monday, June 1. The only other filing day before that is Thursday, May 28. (The court is closed this coming Monday.)
Five of the March cases remain undecided. That means we’re likely to see five opinions filed on two days.
Four of the five cases are reargued death penalty appeals that raise significant issues under California’s Racial Justice Act. (See here, here, and here.) The fifth case involves the constitutionality of blanket papering judges. These are all big-deal cases with opinions that are likely to take up many pages, especially the death penalty appeals.
