What is one of the requirements under the Inter-American "due diligence" doctrine?

The requirement under the Inter-American "due diligence" doctrine that involves investigating violations with promptness and impartiality is essential for ensuring accountability in human rights cases. This principle is rooted in the obligation of states to not only refrain from violating human rights but also to actively protect them. By investigating violations swiftly and fairly, states can demonstrate their commitment to upholding human rights and provide victims with the justice they deserve.

Promptness in investigations is crucial as it helps preserve evidence and ensures witness testimonies are reliable. Impartiality is equally important, as it ensures that the investigation is conducted without bias, allowing for a fair assessment of the facts. Together, these components are fundamental for establishing trust in the legal system and assuring victims that their rights are taken seriously.

The other options, while relevant to human rights broadly, do not directly align with the specific requirements of the due diligence doctrine. Publicizing human rights violations, while important for raising awareness, does not inherently guarantee adherence to due diligence principles. Providing international support to victims is beneficial, but it is not a direct requirement of due diligence. Celebrating cultural diversity, although valuable in promoting inclusivity, is outside the scope of immediate due diligence obligations regarding the investigation of rights violations.
