The right to the truth is often invoked in the context of gross violations of human rights and grave breaches of humanitarian law. The relatives of victims of summary executions, enforced disappearance, missing persons, abducted children, torture, require to know what happened to them. The right to the truth implies knowing the full and complete truth as to the events that transpired, their specific circumstances, and who participated in them, including knowing the circumstances in which the violations took place, as well as the reasons for them.

Each year, on 24 March, the International Day for the Right to the Truth Concerning Gross Human Rights Violations and for the Dignity of Victims is observed.

This annual observance pays tribute to the memory of Monsignor Óscar Arnulfo Romero, who was murdered on 24 March 1980. Monsignor Romero was actively engaged in denouncing violations of the human rights of the most vulnerable individuals in El Salvador.

The purpose of the Day is to:

• Honour the memory of victims of gross and systematic human rights violations and promote the importance of the right to truth and justice
• Pay tribute to those who have devoted their lives to, and lost their lives in, the struggle to promote and protect human rights for all
• Recognize, in particular, the important work and values of Archbishop Oscar Arnulfo Romero, of El Salvador, who was assasinated on 24 March 1980, after denouncing violations of the human rights of the most vulnerable populations and defending the principles of protecting lives, promoting human dignity and opposition to all forms of violence.
