Speaking to PTI, Hegde, who retired as Karnataka Lokayukta last month, scotched reports by a section of the press that the Bihar Chief Minister had approached him in this regard.
But he added: "If a request comes from him (Nitish Kumar), I will do it for free".
Hegde, whose report as Lokayukta on illegal mining forced an indicted B S Yeddyurappa give up the Chief Minister's post, however, stressed that neither was he "seeking" to extend help on his own, nor "canvassing" for such an opportunity.
Responding to questions, he praised the Nitish Kumar Government, saying "fantastic changes have been brought about which are perceptible in many areas. Today, it has outbeaten us (Karnataka) in efficiency; Karnataka is far below...."
Hegde also lauded Bihar's initiatives to set up special tribunals for speedy trial of offences under the Prevention of Corruption Act and the Right to Service Act to provide time-bound public services.
