The Court usually takes about 60 cases per annual term, hears oral arguments from September through April, and then has about half of those cases remaining to decide during the remaining 2+ months of its term. This year, as of 5/1, the Court was already 4 cases behind its opinion-issuing pace from the two prior years.
Since the leak of the Alito draft opinion in the Dobbs abortion case a month ago, it has issued only 4 opinions, and none since 5/23. For post-6/1-issued opinions, the Court is now about 10 cases behind pace from the two prior years. That's now upwards of a 50 percent increase in its amount of work remaining.
