Altogether forty-two states participated in the written phase of the pleadings, the largest number ever to join in proceedings before the Court. Of the five declared nuclear weapon states only the People's Republic of China did not participate. Of the three "threshold" nuclear-weapon states only India participated. Many of the participants were developing states which had not previously contributed to proceedings before the ICJ, a reflection perhaps of the unparalleled interest in this matter and the growing willingness of developing states to engage in international judicial proceedings in the "post-colonial" period.
