According to suspicions, Hirchson failed to report embezzlement in the organization when he served as chairman of the National Workers Labor Federation.
Police officials recently said that they had enough evidence against the minister.
The Hirchson affair began in 2003, when Ovadia Cohen, who is today's deputy mayor of the central town of Ramat Gan, and then CEO of the Nili Association, told Hirchson that he had taken NIS 5.6 million (about USD 1.3 million) from the association to cover his brother's gambling loans on the black market.
Following the incident Hirchson dismissed Cohen from his post, but according to the comptroller's report he failed to report the incident to the police.
In 2005, an accountant investigated the Nili Association and only then it became clear that the money was missing. The accountant filed a complaint to the police, and handed the material over to the State comptroller for further investigation.
