Under what historical context were the majority of the population discriminated against for centuries? Under what historical circumstances did the minority of the population rationalized carry out apartheid policy for centuries? Under what background did they choose forgiveness after being discriminated for centuries? Under what transitional process did a chaos state choose to face the miserable history? In the due process of transitional justice, is there a theoretical framework to support the spirit and core value of transitional justice? Can this theoretical framework explain the experimental results of the restorative justice? The author argues that the Original Position developed by John Rawls's Theory of Justice might be a proper framework for explaining transitional justice in South Africa.
