From the Telegraph.

Following pressure from the non-governmental organisations* that have been heavily involved in setting up the new court, voting rules had also made it impossible for powerful Western nations to elect judges in their own image. Thus, countries had to vote for at least three of the 10 African candidates, two of the six candidates from Asia, two of the seven from Eastern Europe, three of the eight who came from Latin America or the Caribbean and just three of the 12 from a weighty group that included western Europe and Canada.

* I have no doubt that a listing of these "non-governmental organizations" would be be exceedingly educational.
