register those documents which are opposed to public policy and once such document as found in Clause (3) of the Appendix is that “cancellation of sale deeds without the express consent of the parties to the documents”. The above said G.O. was in force when the deed of cancellation was presented for registration on 9.10.2006 before the first respondent. In fact, based on the said G.O., the first respondent at first instance refused to register the deed of cancellation, however, he was constrained to register the same in obedience to the direction issued by this Court in W.P.No.39673 of 2006.

In this case, admittedly, the respondents 2 to 4 had unilaterally cancelled the registered sale deed executed by their power of attorney. It is well settled that a sale is essential an executed contract between two parties on mutually agreed conditions and such contract cannot be unilaterally rescinded, particularly in case of sale deed and by virtue of Section 62 of the Indian Contract Act, 1872, any novation, rescission and alteration of contract must be only bilaterally. In this regard, it worthwhile to refer a decision of a Full Bench of this Court reported in “2011 (2) CTC 1 (Latif Estate Line India Ltd., rep. by its Managing Director, Mr.Habib Abdul Latif versus Hadddja Ammal and others), wherein, the Full Bench of this Court while dealing with similar issue as regards whether once a sale is made absolute by transfer of ownership of the property from the vendor to the purchase, such transfer can be annulled or cancelled by vendor by executing a Deed of Cancellation, it has been held in paragraphs 48, 58 and 59 which are extracted as under:
