The Minnesota Supreme Court has ruled that Donald Trump can be on the Republican Primary ballot in that state. However, the court did not rule on whether Trump is Constitutionally eligible under Section 3 of the 14th Amendment.
The court essentially found that the issue is not ripe because the primary chooses only delegates sent to the party’s national convention, which then decides who the party nominee is. The court described this as an “internal party election.” Part of “a process that allows political parties to obtain voter input in advance of a nomination decision made at a national convention.” You can read the four page decision HERE.
Why should a court be compelled to rule on the hypothetical that Trump might be nominated? If he is not the nominee the court would have no cause to exercise its authority at all. The concern is, at this stage, based on the speculation that Trump will be the nominee.
The matter is dismissed, for now, without prejudice. The petitioners are free to refile, seeking a ruling on the merits, if Trump does win the Republican nomination.
