Riken said Friday that it would ask disgraced former researcher Haruko Obokata for about ¥600,000 in compensation for fees associated with publishing the results of her now-discredited research into so-called STAP cells.
Hiroshi Tsuboi, a member of Riken's board of directors, said the money was equivalent to the fee Riken paid for the papers to be published in the prestigious British science journal Nature in January 2014.
In a Friday news conference, the institute made it clear that after consultation with three lawyers, they had decided not to file a criminal complaint against Obokata. Riken had made the decision Wednesday.
