It is certainly interesting that most observers thought SCOTUS would either hear or decline to hear King the week before.
But on Monday the court did not include King on the list of accepted cases, and the ACA fans cheered.
But Monday afternoon the court noted on the docket that King would be discussed in conference on Friday (yesterday).
Then they went ahead and broke tradition and announced they would hear King on the same day of the conference instead of waiting until Monday to announce.
Somehow I tend to think the court wanted to see what happened Tuesday before they considered whether to take this case.
