Colombia's tortious liability regime has not yet recognized the existence of a duty of the victims to mitigate the damages they suffered.However, some Colombian civil and constitutional institutions may be used to deduce its existence; particularly the notions of "good faith" and "direct damages".Accordingly, the purpose of this paper was to solve the following legal problem: considering the constitutional principle of good faith and given that only direct damages may be compensated in Colombia, is there a victim's duty to mitigate the damages he suffered within Colombia's non-contractual liability regime?The analysis was based upon a conceptual, legal, and case-law review of the notions of good faith, direct damage, and duty to mitigate damages.Based on this methodology, among other things, it was concluded that within Colombia's tortious liability, there is a victim's burden to mitigate the damages he suffered, inferred from the requirement that damages must be direct in order to be compensated.As a consequence, both contractual and noncontractual liability regimes in Colombia, contemplate a victim's burden to mitigate damages.
