International efforts to codify the law on trafficking in persons have been evolving since the early twentieth century. This paper re-examines this journey of law and divides the existing international and domestic legal regimes into three categories: the rescue model, quasi-curative model, and curative model. The study proposes the development of an effective legal model, which may rest on the twin pillars of shared state responsibility and long-term assistance to trafficking victims. In this model, it is argued that the enunciated principles of prosecution, protection, and prevention to combat human trafficking should not be dealt with in isolation, but in combination with the concepts of state responsibility and international financial co-operation to provide long-term assistance to the victims. My central argument focuses on the suitable legal regime in which the prosecution strategy is to successfully prosecute traffickers in person, improve survivors’ protection, and reinvigorate obligations imposed on the states.
