The court of special judge G Sridevi has fixed the next date of hearing for March 1.
Singh was produced in the court amid tight security in the afternoon, Kavi Nagar SHO Ashok Shishodia said.
CBI prosecutors did not seek extension of the police remand of Singh for the third time. His police custody has earlier been extended twice by the court.
On February 2, Singh was arrested by CBI in connection with a corruption case.
The cases have been registered on the direction of the Lucknow Bench of the Allahabad High Court.
