A bench comprising Chief Justice T S Thakur, Justices A K Sikri and R Banumathi said the fresh plea also needed to be heard by the same bench headed by Justice Ranjan Gogoi which had earlier appointed Justice Singh as Lokayukta.
The court had on December 16 last year had exercised its constitutional authority and appointed Justice Singh as Lokayukta, saying the constitutional functionaries-- the Chief Minister, the leader of opposition and the Chief Justice of Allahabad High Court--had failed to comply with its orders by not appointing the chief of the state's anti-graft ombudsman.
The state government had also told the court that it will not go ahead with the oath taking ceremony of Justice Singh as Lokayukta till the apex court had heard the fresh plea.
During the hearing, lawyers Prashant Bhushan and Kamini Jaiswal, appearing for Gupta, were today allowed to bring on record the communication between the Chief Minister and the Chief Justice of the High Court on the issue of selection of Lokayukta. The court will now hear the matter on January 19.
The plea seeks a direction for quashing of the December 18 order of the government appointing Justice Singh as Lokayukta.
