Arya furnished the information at the Assembly in response to a question raised by Congress MLA Umang Singhar.
The state government has sent the proposal to expel the IAS couple after an income tax raided their house in 2010, following which a case of disproportionate assets was filed against them.
The government has sent proposals in this regard thrice, the minister said, adding, that the Centre has to take a decision on the issue.
He also informed that after getting sanction for prosecution in the matter on January 20, 2014, challan was filed in the court by the probe agency on March 1 for initiating the process of forfeiting disproportionate assets.
In a written reply to the same question, the government also informed that a committee constituted under the chairmanship of former Chief Secretary, Narmala Buch, found the allegations against the couple as totally correct except under the All India Services (Conduct) Rule, 1968's rule 3(2).
While Arvind Joshi was posted as then Principal Secretary of Jail, Tinu was the Secretary of Women and Child Development department.
Soon after the raids, the couple was placed under suspension by the state government.
The IT raid at their official residence of Joshi couple had also yielded over Rs 3 crore in cash and documents of other assets, which were "grossly disproportionate" to their known sources of income.
