We're closely monitoring the events at the Supreme Court. The Justices will enter the courtroom momentarily. The health care decision will likely be the last of those issued today, according to scotusblog.com.
Someone asked the moderators there why healthcare is being decided on the last day of the term. The answer:
For one thing, it was only argued in late March and it often takes several months to write opinions in complicated cases. In addition, in big cases where there are multiple opinions, it takes a while for the dissents and concurrences to get written. Finally, the Justices often just take as much time as is available to polish their opinions in big cases.
