Section 8-316. Ballots; mutilated or spoiled

If a ballot is found to be
  defective or mutilated before it is delivered to the voter, its stub and
  the stubs of all other ballots in the set shall be detached  immediately
  and  placed  in  the  box  for  stubs, by the clerks, or if there are no
  clerks by the inspector assigned to the duty of delivering ballots,  and
  all the ballots of that set immediately shall be marked "cancelled", and
  placed  in the box for spoiled and mutilated ballots. If a voter returns
  a ballot as defective, mutilated, defaced, or wrongly marked,  he  shall
  also return all the other ballots of the set, if any, and such clerks or
  inspector  shall  likewise  remove their stubs, placing all the stubs in
  the box for stubs and all the ballots of the set in the box for  spoiled
  or  mutilated  ballots,  first  marking the ballots "cancelled". In each
  case, the voter shall receive another ballot or set of  ballots,  unless
  not entitled thereto.
