-9e. Relations with other bodies 17. The CPT has maintained relations with other bodies, both governmental and non-governmental, which are active in fields falling within the Committee's terms of reference. The ongoing contacts between the Committee and the International Committee of the Red Cross on matters of mutual interest deserve to be highlighted (cf. also the CPT's 1st General Report; CPT (91) 3, paragraph 44). Further, working relations have now been established between the CPT and the Council on Penological Co-operation. 18. In August 1992 the United Nations Deputy Secretary General for Human Rights invited the CPT to submit observations on the draft Optional Protocol to the United Nations Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment, which had been proposed by the Costa-Rican Government on 22 January 1991. The observations subsequently forwarded by the CPT are reproduced in Appendix 5. Further, in October 1992, the CPT's 2nd Vice-President took part in a hearing before the Working Group examining the draft Optional Protocol, in order to explain the CPT's activities. 19. Individual CPT members are increasingly attending seminars and symposia in order to speak about the Committee's work. Particular reference might be made to the Training Forum for Prison Governors from Central and Eastern European countries held in Warsaw in October 1992; the Committee's 1st and 2nd Vice-Presidents participated in this meeting. 20. Finally, the President of the CPT attended a hearing with the Ministers' Deputies on 23 June 1992, in the framework of their consideration of the Committee's 2nd General Report. Such hearings provide an invaluable opportunity for a wide-ranging discussion about the CPT's activities, and the Committee hopes that they will become an annual tradition.
