MOSCOW (Sputnik) – Lagarde was put under investigation in August 2014 for authorizing the payment of 403 million euro ($434 million at the current exchange rate) in an out-of-court settlement to Tapie.
Lagarde is accused of failing to block an arbitration process that ended the longstanding dispute between former state-owned bank Credit Lyonnais and Bernard Tapie, a supporter of then French President Sarkozy.
It is known that the businessman walked away with an initial award of about 285 million euros ($314 million).
At the time, Lagarde served as finance minister in the government of President Nicolas Sarkozy.
In December 2015, a French court ordered Lagarde to stand trial for alleged negligence in the affair.
