This is just approval for the cases to be heard sometime in the future. No ruling for a long time.
Four justices must agree to have the cases before the Supreme Court. If there was not a fourth before Kavanaugh joined, it’s a bad sign.
I was just speculating that some conservative justices might have wanted to wait until a new justice was in place, rather than hear the case while there was a vacancy that could lead to a 4-4 ruling.
