The 16 permanent judges are elected by the General
Assembly of the United Nations for a term of four years. They can
be re-elected.
The ad litem judges are drawn from a pool
of 27 judges. They are also elected by the General Assembly of the
United Nations for a term of four years, but they are not eligible
for re-election. An ad litem judge can only serve at the
ICTY following his/her appointment by the Secretary-General on the
recommendation of the President of the Tribunal in order to sit
on one or several specific trials for a period of up to three years.
The judges are divided between three Trial Chambers
and one Appeals Chamber. Each Trial Chamber consists of three permanent
judges and a maximum, at any one time, of six ad litem judges.
A Trial Chamber may be divided into mixed sections of three judges
(one permanent and two ad litem, or two permanent and one
ad litem). Each Trial Chamber can be comprised of up to three
sections. The Appeals Chamber consists of seven permanent judges:
five from the permanent judges of the ICTY, and two from the 11
permanent judges of the International Criminal Tribunal for Rwanda
(ICTR). These seven judges also constitute the Appeals Chamber of
the ICTR. Each appeal is heard and decided by five judges.
The judges represent the main legal systems in
the world and bring to the Tribunal a variety of legal expertise.
The judges hear testimony and legal arguments, decide on the innocence
or the guilt of the accused and pass sentence.
The permanent judges also have important regulatory
functions: they draft and adopt the legal instruments regulating
the functioning of the ICTY, such as the Rules of Procedure and
Evidence.
