2. This case had a chequered history on account of certain earlier proceedings, which occurred before this Court wherein this Court entertained a genuine doubt as regards the bona fides of the petitioners in prosecuting the litigation. This led to orders being passed from time to time in the writ petitions and ultimately, by order dated 20.4.2016, this Court directed the Crime Branch CID to investigate into the matter and submit a report with regard to the aspect as to whether there is a case of impersonation by the petitioners and as to whether there is an attempt to usurp the land owned by the Government.

3. The Deputy Superintendent of Police, CBCID, Metro-I, Chennai-8 conducted a thorough probe and submitted a detailed confidential report dated 16.6.2
