No, it's the General Assembly, which dismisses every year no later than April 30.
GOP Supermajority should have considered a bill to render IU's plans moot, but they did pass HB 1405 and signed by the Goobernor, which prohibits vaccine passports.
IU threaded the needle by not mandating a passport. Their Attorney General Rokita has held IU to Ind. Code ch. 16-39-11, but now it would take a Special Session to pass the specific law to stop IU ... which is the unspoken paradigm to fix the problem behind every federal court stop all the way up to cert ...
The more likely alternative is to fix the problem next January with their statehouse supermajority plenty intact, and there is serious interest in a companion bill to punish IU with a secondary fund-stripping bill.
With the general assembly not in session, the governor would have been the logical source for relief.
I suspect the students did not have the best representation.
