President Maithripala Sirisena has signed the Office on Missing Persons Act.
It provides for the establishment, administration of the office and the provision of functions.
The special gazette notification states that the 1st to 5th provisions of the act should be implemented from the 15th of September.
The Draft Bill for the establishment of the Office of Missing Persons was approved with amendments in Parliament last year.
The draft bill was tabled following the disapproval of several members representing the Opposition.
The establishment comes with the view of searching and tracing missing persons, identifying appropriate mechanisms, submission of recommendations to take measures on missing persons, protecting the rights of missing persons and relatives, identifying channels that missing persons and their relatives can collate data related to missing persons obtained by government institutions and to centralize all available data.
The establishment of the Missing Persons Office was one of the pledges of the government to the United Nations Human Rights Council.
