You are correct that it was doomed from the beginning, as any court observer would see.
The Constitution is very clear on the matter, so much that even non-lawyers can understand it:
"In all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party, the supreme Court shall have original Jurisdiction. In all the other Cases before mentioned, the supreme Court shall have appellate Jurisdiction"
There are only two kinds of cases that can start at the supreme court: those affecting ambassadors and other specific people, and those cases brought by a state.
Everything else must be an appeal of a lower court that has been brought to the supreme court.
Since they were bringing it up as an original complaint, but it doesn't affect one of those people or have a state as a party, there is no constitutional way the SCOTUS could accept the case. The original case must be heard at a lower level, then the supreme court could hear the appeal.
