witness

... Before any disciplinary award is pronounced, the accused shall be given precise information regarding the offences of which he is accused, and given an opportunity of explaining his conduct and of defending himself. He shall be permitted, in particular, to call witnesses and to have recourse, if necessary, to the services of a qualified interpreter. The decision shall be announced to the accused prisoner of war and to the prisoners' representative. ...

... The prisoner of war shall be entitled to assistance by one of his prisoner comrades, to defence by a qualified advocate or counsel of his own choice, to the calling of witnesses and, if he deems necessary, to the services of a competent interpreter. He shall be advised of these rights by the Detaining Power in due time before the trial. ...

... The advocate or counsel conducting the defence on behalf of the prisoner of war shall have at his disposal a period of two weeks at least before the opening of the trial, as well as the necessary facilities to prepare the defence of the accused. He may, in particular, freely visit the accused and interview him in private. He may also confer with any witnesses for the defence, including prisoners of war. He shall have the benefit of these facilities until the term of appeal or petition has expired. ...

... A communication on this subject shall be sent immediately to the Protecting Power. Statements shall be taken from witnesses, especially from those who are prisoners of war, and a report including such statements shall be forwarded to the Protecting Power. ...

... Representatives or delegates of the Protecting Powers shall have permission to go to all places where prisoners of war may be, particularly to places of internment, imprisonment and labour, and shall have access to all premises occupied by prisoners of war; they shall also be allowed to go to the places of departure, passage and arrival of prisoners who are being transferred. They shall be able to interview the prisoners, and in particular the prisoners' representatives, without witnesses, either personally or through an interpreter. ...

... IN WITNESS WHEREOF the undersigned, having deposited their respective full powers, have signed the present Convention. ...
