respondent, towards the additional Performance Guarantee in Ext.P1, making it clear that the adjustment would not absolve the petitioner from the future liability. The petitioner has now filed this Writ Petition pointing out that the 4th and part bill in respect of the very same work under the 4th respondent for a higher amount of Rs.1,38,94,814/- is due to him and funds have been allotted for it by the Central Government. Therefore, he submitted an application before the 4th respondent to substitute the 4th bill in the place of the third bill which this Court had allowed as per Ext.P2 interim order. The said request was rejected as per Ext.P4 letter. This Writ Petition is filed challenging Ext.P4 and stating that in similar cases this Court has allowed substitution of the bills. It is pointed out that in view of the orders passed by the Government on 23.06.2020 and 16.10.2020, the respondents are bound to allow the request of petitioner.
