“What is the next step - does it have a date? Are there hurdles or conditions that the case has to meet that are known? (what are they and who decides?)
Thanks in advance for replies.”
SCOTUS will decide.
It will be a decision of first impression (1st time) on some issues and second impression on another.
It will be one of the most important decisions in the history of American Jurisprudence.
It will. And we are privileged to witness it.
Be patient.
