Section 130.52. Number of votes required

(a) No person shall be convicted
  of any offense, except as provided in subdivision (b) of section  130.45
  of  this  chapter,  or  by  the concurrence of two-thirds of the members
  present at the time the vote is taken.
    (b) All sentences shall be determined by the concurrence of two-thirds
  of the members present at the time that the vote is taken.
    (c) All other questions to be decided by the members of a  general  or
  special  court-martial  shall  be  determined  by a majority vote, but a
  determination to reconsider a finding  of  guilty  or  to  reconsider  a
  sentence,  with  a  view toward decreasing it, may be made by any lesser
  vote which indicates that the reconsideration  is  not  opposed  by  the
  number  of votes required for that finding or sentence.  A tie vote on a
  challenge shall disqualify the member challenged.    A  tie  vote  on  a
  motion  for  a  finding  of  not  guilty  or on a motion relating to the
  question of the accused's sanity shall be a  determination  against  the
  accused.    A tie vote on any other question shall be a determination in
  favor of the accused.
