With the February sitting now underway after an extended recess, Court-watchers got the busiest week of the term thus far. The Court released seven decisions in argued cases involving all of the following: immigration law, tax law, capital sentencing in Arizona, international treaty law, criminal procedure, ERISA, and the ACCA. We saw a per curiam decision in an Establishment Clause case out of Puerto Rico, and four individual opinions relating to Monday’s orders list. Finally, the Justices heard oral argument in four cases and granted a case for next term. Block off some time for this one; here’s your extensive recap of the action at the Supreme Court this week.
