"The state government made repetitive efforts to amend a 60-years-old Act that does not permit action against mayors of corporations for wrongdoings.
"It is pitiable that the state government is not empowered to take action against corrupt mayors...It is a joke on democracy," Khan said, adding there was an attempt to "defend dishonest people and encourage corruption".
"The Governor has sent Uttar Pradesh Nagar Nigam (Amendment) Bill, 2015 and UP Nagarpalika Vidhi (Amendment) Bill, 2015 to President Pranab Mukherjee for reference," Raj Bhavan had said on Thursday.
Khan had earlier alleged the Bill was not given assent so that mayors could not be punished for their "dishonesty".
He had also accused the Governor of stalling several bills by not giving his assent and that it was giving an impression that Ram Naik was working under the "influence of a party".
