MOSCOW, October 24 - RAPSI. The Moscow City Court has upheld the lower-court's dismissal of a complaint filed by the mother of Sergei Magnitsky, a legal consultant who died in the pre-trial detention center, the Russian Legal Information Agency (RAPSI) reports from the courtroom.

The woman requested to cancel the decision to resume the criminal case against her son.

"The Tverskoy District Court's decision to dismiss the complaint is legal and founded," a judge of the cassation board said.

Magnitsky, 37, who was accused of corporate tax evasion in relation to his work for the Hermitage Capital investment fund, died in an isolation ward in November 2009. According to the Prosecutor General's Office, his death was caused by cardiovascular insufficiency.

His death evoked a major public outcry.

The criminal case against Magnitsky was terminated by the Investigative Committee due to his death, but the Prosecutor General's Office decided to resume the investigation.

Magnitsky's relatives have demanded that the case against him be dropped.
