Pure BS by whomever fed you those ‘standing’ conditions because this is not an example of a dispute brought by an individual or injured party against a state of which the outcome is confined to the states jurisdiction.
NO... It is a grievance, a dispute BETWEEN states which stands as a NATIONAL issue, and indeed falls exclusively under federal jurisdiction with UNASSAILABLE STANDING!
SCOTUS has not the authority to turn down lawsuits between states!
You could read any of the 4 briefs in opposition where the Attorney Generals spell out exactly what must be satisfied and how Texas did not adequately address. Again, from the very beginning, many law professors and legal pundits kepts saying there were too many defects in the complaint and the case would be tossed on lack of standing. SCOTUS basically accepted the case (to keep the “cannot turn down”) and immediately tossed it on lack of standing.
