decisions in N.P.Thirugnanam (D) by lrs vs. Dr.R.Jaganmohan Rao & ors., JT 1995 (5) SC 553; Aasman Investments vs. Shri K.L.Suneja & Anr, 2011(181) DLT 156; Boots Pharmaceuticals Ltd. Vs. Rajinder Mohindra, 177(2011) DLT 260; J.L.Gugnani (HUF) vs. O.P.Arora & Ors., (2011) IX AD (Delhi); Spring Valley Finance vs. Smt. Prakash Kaur, 148(2008) DLT 767; and Ravi Sood & anr vs. Veer Bala Sharma, 71(1998) DLT 254, to contend that the ingredients of Section 20 of the Specific Relief Act, 1963 have to be satisfied before specific performance of sale agreement can be ordered and in the instant case, there was clear lack of willingness on the part of respondent to pay the unearned increase, thereby frustrating the Agreement of sale of 23rd January, 1984 (Ex.DW-1/1). Thus, it was vehemently urged by learned senior counsel for the appellant that the impugned judgment of 17th October, 2006 deserves to be set aside and the suit of appellant ought to be decreed and the counter claim of respondent be dismissed.
