Bobert is the one who is attempting to rebut and has not suceeded. Instead he says no one can prove anything which is apparent in his feeble attempts.

Therefore the evidence documents are admitedly forged, the charges are unprovable and the verdict is not guilty.

The way Bobert would have it is the charges are valid because invalidity of the forged documents is unprovable and the verdict is guilty, inviolation of civil rights.
