Post 8 makes it sound as though one justice can sink your
case. This is likely the justice who is in charge of your circuit. Maryland is in the 4th circuit. Roberts is in charge of that one.
Now if it gets past that stage then it takes 4 votes?
Since it wasn’t an emergency, there probably weren’t four justices who wanted to hear the case, unfortunately.
One justice can’t overrule the rest of the Court.
Actually that is the full description, and what it says is thea the emo for the case is assigned to 1 justice, who may deny it be themselves. If not he passes it to all justices and then it requires only 4 vote yes to hear the case. So it could have been assigned to a liberal justice and they decided on their own to dent taking the case.
