FROM BONDAGE TO FREEDOM 61 punishing traffickers, procurers and exploiters of prostitutes, State Parties are required to abolish any form of registration or supervision of prostitutes,118 take measures to prevent prostitution and rehabilitate victims of prostitution119, take measures in connection with immigration and emigration procedures to deal with trafficking in persons120; repatriate victims of international traffic;121 and supervise employment agencies to prevent those seeking employment from being exposed to the dangers of prostitution122. The 1949 Convention obligates the State Parties to regard offences established by the Convention as extraditable offences in any extradition treaty or otherwise123. It also follows the principle of ‘aut dedre aut punire’ that is applied when a person is refused to be extradited. In this case, the State, which refuses to return the person must prosecute and punish the person according to its own laws124. Cross border cooperation is seen to be an important tool in the fight against immigrant prostitution and trafficking and the 1949 Convention contains a number of substantive and procedural provisions on this issue. Detailed guidance is also provided on the internal coordination and centralization of anti-trafficking efforts. It calls for compilation of all information calculated to facilitate the prevention and punishment of the above-mentioned offences125. The State Parties are obligated to take preventive measures against trafficking of women such as provisions of public and private educational, health, social, economic and other related services. State Parties are obligated to take or to encourage measures for the prevention of prostitution and for the rehabilitation and social adjustment of the victims of prostitution.126 The prevention measures also involve strengthening of immigration and emigration policies that protect immigrants or emigrants from becoming victims of trafficking127. Arranging for public warning of the dangers of trafficking and ensuring supervision of railway stations, airports, seaports and other public places are some other measures 118 Ibid Art. 6 119 Ibid Art. 16 120 Ibid Art 17. 121 Ibid Art. 19 122 Ibid Art. 20. 123 Ibid, Art. 8 124 Ibid, Art. 9. 125 Ibid, Art. 16. 126 Ibid, Art. 16. 127 Ibid Art. 17.
