False.

Judge ordering something can be brought to court to review if the order was lawful. Judge making judicial decision - that is, not ordering something to support that decision, but actually deciding - is immune, but that is decision of the limited scope - it's not an action. Decision itself can be reviewed, so there's principally less scope for possible intentional or unintentional errors.

Surely you acknowledge what a giant, wide, grey line of a no-man’s-land you just painted.
