Mr Singh's wife Pratibha Singh was also summoned as accused. They have been directed to appear on May 22 before the court of Special Judge Virender Kumar Goyal.
Besides the 82-year-old Congress leader and his wife, the others asked to appear as accused are Chunni Lal Chauhan, Joginder Singh Ghalta, Prem Raj, Vakamulla Chandrasekhar, Lawan Kumar Roach and Ram Prakash Bhatia.
The charge sheet, running into over 500 pages, claims that Mr Singh had amassed assets worth around Rs 10 crore which were disproportionate by 192 per cent to his total income during his tenure as a Union minister.
The final report, filed against Mr Singh and eight others for alleged offences punishable under sections 109 (abetment) and 465 (punishment for forgery) of IPC and Prevention of Corruption Act, arrayed around 225 witnesses and 442 documents.
Mr Chauhan was arrested by Enforcement Directorate on July 9 last year in a separate money laundering case related to the present case.
The matter was transferred by the Supreme Court to the Delhi High Court, which on April 6, 2016 had asked the CBI not to arrest Singh and directed him to join the probe.
On November 5 last year, the apex court had transferred Mr Singh's plea from the Himachal Pradesh High Court to the Delhi High Court, saying it was not expressing any opinion on the merits of the case, but "simply" transferring the petition "in interest of justice and to save the institution (judiciary) from any embarrassment".
