registration dated 29.03.2006. The 2^nd petitioner is a dealer of

passenger vehicles manufactured by Mercedes-Benz and a

member of the 1^st petitioner Association. The petitioners have

filed this writ petition under Article 226 of the Constitution of

India, seeking a writ of certiorari to quash Ext.P2 circular dated

06.08.2018 issued by the 2^nd

respondent Transport

Commissioner, whereby the Deputy Transport Commissioner,

the Regional Transport Officers and the Joint Regional Transport

Officers are directed to take necessary steps to ensure

registration of the vehicles kept by automobile dealers for test

drive, on the ground that some of the automobile dealers are

using such vehicles for test drive for longer periods and

thereafter, selling those vehicles at a lower price, which cause

revenue loss to the State Exchequer. The petitioners have also

sought for a writ of certiorari to quash Ext.P4 check report
