Participants.

The Institute maintains a reasonably balanced representation from the nations of the world and extends membership only to those who have demonstrated scholarly attainment and who are likely to be free from political pressures.The statutes and regulations governing the Institute establish three categories of participants：members，associates，and honorary members.The associates——limited to seventytwo——are drawn from candidates“who have rendered service to international law，either in the domain of theory or of practice”1 and who have been presented either by their national associations or by the Bureau of the Institute.The members——limited to sixty——are chosen from among the associates.The honorary members——not limited in number by the statutes but sparingly chosen in practice——are selected from the ranks of members or associates or from any other persons who distinguish themselves in the field of international law.

All participants share in the scholarly and issue-oriented activities of the Institute.Only the members deal with administrative matters such as finances，decisions concerning the statutes and regulations，election of members and honorary members，or the election of members of the Bureau or of the Council of the Auxiliary Foundation.(https://www.daowen.com)

To assure representation of the various judicial systems of the world，the Institute permits no state to have more than one-fifth of the members or associates allowed in each category，and the Bureau of the Institute may allocate to candidates from parts of the world which are under-represented，up to one-third of the number of associate memberships open in any given session.As of May，1971，the Institute had a total of 115 members，associates，and honorary members drawn from forty states，the preponderant^[8]number being from Western countries2.
