Egypt's Court of Cassation on Saturday upheld a ruling to acquit former president Hosni Mubarak's chief of staff Zakaria Azmy of charges of illicit gains.
The case dates back to 2012 when a criminal court first sentenced Mubarak's former chief of staff to seven years in jail on corruption charges.
Azmy was then fined EGP 36.5 million (worth approx. $6 million in 2012) after being found guilty of making illicit profits of some EGP 44 million.
In February 2017, a Cairo criminal court released Azmy after he was found innocent of the charges.
The Court of Cassation turned down a prosecution appeal against the acquittal.
Saturday's court decision is final and cannot be appealed.
