In September 1984, the UN Secretary-General (Respondent) offered five-year fixed-term contracts as interpreters to Rong Qiu, Kefu Zhou, and Jiping Yao (Applicants), who had just completed the UN training course for interpreters at the Beijing Institute of Foreign Languages. The letters of appointment accepted by the Applicants stated that they were “on secondment from the Government of China.” They received very good performance ratings, and in the spring of 1989 their department recommended that they be offered probationary, career-track appointments when their contracts expired.
