It means nothing at the moment. It was just procedural:
"But the justices took pains to make clear they were not ruling on the legality or viability of Youngkin’s mask-optional order.
“By this dismissal,” they wrote in a footnote, “we offer no opinion on the legality of EO 2 [Youngkin’s mask-optional order] or any other issue pertaining to petitioners’ claims.”
To be more clear:
"The seven justices on the state Supreme Court dismissed the suit Monday, writing in a three-page opinion that it was impossible to request the relief the parent plaintiffs had sought — writs of mandamus and prohibition that would have prevented Youngkin and the Chesapeake School Board from declaring masks optional in school — because such writs were not applicable or issuable in this case."
Basically, we are all exactly where we were 1 second before they rule. The EO is still on hold as this conti ues to move forward.
