The petitioners are owners of the agricultural land admeasuring Acs.30.31 guntas in survey No.80 of Hafeezpet Village of Serilingampally Mandal in Ranga Reddy District. They statedly purchased the said land from the Decree Holders in C.S.No.14 of 1958 on the file of this Court. There was protracted litigation with regard to the property in survey No.80 between the Government of Andhra Pradesh and the Decree Holders in C.S.No.14 of 1958. The Decree Holders as well as the petitioners herein got the property in survey No.80. There is no dispute that ultimately the property was settled in favour of the petitioners. Thereafter the petitioners herein through their General Power of Attorney (GPA) Holder approached the Mandal Revenue Officer, Serilingampally Mandal (MRO), second respondent herein, for grant of mutation. By proceedings dated 10.2.2006, the MRO granted mutation in favour of the petitioners in respect of the land in survey No.80 admeasuring Acs.30.31 guntas. However, the Revenue Divisional Officer, Chevella Division (RDO), issued show cause notice to the petitioners in purported exercise of power under Section 5(5) of A.P. Rights in Land and Pattadar Pass Books Act, 1971 (RoR Act, for brevity) purportedly acting in accordance with circular letter addressed by the District Collector, Ranga Reddy District, with regard to the alleged contravention of the provisions of Urban Land (Ceiling and Regulation) Act, 1976 (ULC Act, for brevity). The petitioners assailed the said notice of the RDO in a writ petition being W.P. No.11637 of 2006. By an order dated 07.7.2006, this Court set aside the same holding that Section 5(5) of RoR Act does not confer suo motu powers on the RDO to entertain an appeal. Thereafter, the Joint Collector-II – first respondent herein; issued the impugned notice to the petitioners and also suspended the proceedings of the MRO dated 10.2.2006 whereunder mutation was granted to the petitioners. In the impugned show cause notice, the petitioners were asked to appear for hearing on 08.8.2006. The impugned notice is challenged on many grounds.
