But see that’s the thing, he hasn’t actually done anything.
he said he was going to issue an order, but he didn’t.

He directed the agency that enforces immigration law to change it’s procedures.
That lawless change is what’s being challenged, not an ‘order’.
There’s a couple of ‘memos’ from him directing the change.
The focus is on taking action against the Secretary of the DHS for issuing the memorandums to execute the action.
