could not be completed within the stipulated contract period; that on the instructions of the respondents, the petitioner has applied for extension of contract from 24.07.2009 up to 20.03.2010; that the contract was accordingly extended up to 31.10.2011; that the petitioner has extended the validity of the bank guarantee up to 31.07.2015; and that subsequently, the petitioner has requested the respondents to close the agreement and release the amount, vide its letter, dated 11.09.2014. However, the petitioner has received the communication, dated 08.10.2014, along with which impugned letter, dated 09.04.2014, was also received to the effect that the agreement is cancelled with effect from 09.04.2014. The petitioner has questioned this action on the ground that this is in violation of principles of natural justice besides being against “canons of contract management.” Sri Prasad Rao Vemulapalli, learned counsel for the petitioner, made strenuous efforts to impress upon this Court to entertain the Writ Petition for adjudication on merits. He has submitted that due to fundamental breaches committed by the respondents, the petitioner could not complete the work in time and that, therefore, there is no justification for terminating the contract. But, however, this Court has not felt persuaded to entertain this Writ Petition for the reason that the dispute involved in the Writ Petition arises under a concluded contract. Ordinarily, Writ Petitions filed raising disputes arising out of concluded contracts are not entertained by this Court under Article 226 of the Constitution of India as such disputes fall in private law field. (See: M/s. Radhakrishna Agarwal & others vs State of Bihar & others, State of U.P. v. Bridge & Roof Co.(India) Ltd., Asstt. Excise Commr. v. Issac Peter). The present case does not fall in the line of cases where the exceptions are carved out by the Supreme Court such as ABL International Limited v. Export Credit Guarantee Corporation of India Limited and Mahabir Auto Stores & others Vs Indian Oil Corporation & others.
