The International Criminal Court has been asked to investigate the role of former Namibian President Sam Nujoma, in the deaths of thousands of people.
Sam Nujoma is seen as Namibia's founding father
The Namibian Society of Human Rights lodged a submission with the ICC, accusing Mr Nujoma and other officials of instigating the deaths of Namibians.
Some were allegedly killed after being accused of spying for South Africa.
Mr Nujoma, 78, led Namibia's struggle for independence from South Africa and became its president in 1990.
He stepped down in 2005 after serving three terms in office.
The NSHR said it had evidence that bodies were pushed down a deep crevasse near the border with Angola.
The petition calls for Mr Nujoma and three others to be investigated for "instigation, planning, supervision, abetting, aiding, defending and or perpetuating" the disappearances of some 4,200 people.
The ruling South West Africa People's Organisation (Swapo) has denied having any role in the deaths.
