ACA and the Supreme Court

I guess I could look it up, but when everybody here knows but me, it would be a timesaver if somebody would just be nice enough to tell me...

Whatever happened when the Supreme Court was ruling on the ACA case brought by the Republicans? Had to do with (17?) States not having subsidies and the federal government providing them, or something like that. I used to know but it's been so long since the case was discussed I forgot to listen for the ruling. It was supposed to be on a few Saturdays ago, and I missed it, buc I can't understand why MSM hasn't mentioned it.

Thanks a lot...
