My understanding, from a quick 5 minute skim, is that it may be. It's being sent back to the district court for reconsideration.

Basically what seems to have happened is this:

1. Robles sued Dominoes alleging their website violated the ADA.

2. The district court dismissed the suit, saying the DOJ needs to provide guidance on the standards that websites must meet, if the court is to hold them to the ADA. They don't examine the question of the phone.

3. The appeals court steps in and says that no, the district court was wrong to dismiss it for that reasons, and sends it back to the district court.

4. Dominoes appeals to SCOTUS, saying "help, the appeals court got it wrong, please step in!" SCOTUS declines to get involved, so the case will go back to the district court, which may still find that the phone access provided is an adequate accommodation.
