When will the Supreme Court make a final decision?

The climate rule will remain frozen while its legal status is uncertain, and that will take awhile. A Federal Appeals Court will hear oral arguments on the rule on June 2, and is expected to issue its decision later this year. An appeal to the Supreme Court is all but certain. If the justices agree to hear the case, a ruling is unlikely before June 2017. The Supreme Court's decision on the final rule will either unfreeze the hold and require states to go back to creating their plans, or it would simply overturn the rule entirely.
