  SECTION VI RELATIONS BETWEEN PRISONERS OF WAR AND THE
  AUTHORITIES
  CHAPTER I COMPLAINTS OF PRISONERS OF WAR RESPECTING
  THE CONDITIONS OF CAPTIVITY
  ARTICLE 78
  Prisoners of war shall have the right to make known to the military authorities in whose power
  they are, their requests regarding the conditions of captivity to which they are subjected.
  They shall also have the unrestricted right to apply to the representatives of the Protecting
  Powers either through their prisoners' representative or, if they consider it necessary, direct, in
  order to draw their attention to any points on which they may have complaints to make
  regarding their conditions of captivity.
  These requests and complaints shall not be limited nor considered to be a part of the
  correspondence quota referred to in Article 71. They must be transmitted immediately. Even if
  they are recognized to be unfounded, they may not give rise to any punishment.
  Prisoners' representatives may send periodic reports on the situation in the camps and the needs
  of the prisoners of war to the representatives of the Protecting Powers.
  CHAPTER II PRISONER OF WAR REPRESENTATIVES
  ARTICLE 79
  In all places where there are prisoners of war, except in those where there are officers, the
  prisoners shall freely elect by secret ballot, every six months, and also in case of vacancies,
  prisoners' representatives entrusted with representing them before the military authorities, the
  Protecting Powers, the International Committee of the Red Cross and any other organization
  which may assist them. These prisoners' representatives shall be eligible for re-election.
  In camps for officers and persons of equivalent status or in mixed camps, the senior officer
  among the prisoners of war shall be recognized as the camp prisoners' representative. In camps
  for officers, he shall be assisted by one or more advisers chosen by the officers; in mixed camps,
  his assistants shall be chosen from among the prisoners of war who are not officers and shall be
  elected by them.
  Officer prisoners of war of the same nationality shall be stationed in labor camps for prisoners of
  war, for the purpose of carrying out the camp administration duties for which the prisoners of
  war are responsible. These officers may be elected as prisoners' representatives under the first
  paragraph of this Article. In such a case the assistants to the prisoners' representatives shall be
  chosen from among those prisoners of war who are not officers.
  Every representative elected must be approved by the Detaining Power before he has the right to
  commence his duties. Where the Detaining Power refuses to approve a prisoner of war elected by
  his fellow prisoners of war, it must inform the Protecting Power of the reason for such refusal.
