The Supreme Court issued four decisions today on cases argued in April, including a big one concerning patents, but no opinion still on the March-argued cases involving marriage. All four cases were unanimous decisions.

The next date for issuing opinions is Monday, June 17, at 10 a.m. EDT. The court has 19 left to issue this session.

According to the court’s public information office, the last day of the session is not yet known, but many veteran observers expect it to be Monday, June 24, or soon thereafter.
