When injustice arises in the form of human rights violation and justice cannot be obtained at once, documentation is needed. Documentation helps to seek truth that is needed for justice, to directly assist the victims in the form of reparation and to collect historical records to prevent it from happening again.
Reparation is like helping the survivors build their life again after the chaos. In the context of transitional justice, it's about acknowledging and addressing the harm suffered by individuals or communities.
The truth-seeking policy is like the missing piece of a puzzle. It's about uncovering and acknowledging the facts, the truth behind what happened.
