Of course, one must look at all the surrounding circumstances and decide each case according to its own particular facts : see Neta Ram and others v. Jiwan Lal and another. Air 1983 Sc 499.
(13) I accept that a landlord is bound to give a satisfactory explanation for not occupying any other premises belonging to him that have fallen vacant shortly before a petition for recovery of possession is filed or whilst it is pending : see P.S. Devgun v. S.P. Walia 1975 Rlr Note 71 page 63 : Satya Pal v. Smt. Parsani Devi, 1974 Rcr 508. This really follows from the requirement of section 14(1)(e) that the land lord has 'no other reasonably suitably residential accommodation'. But, the other accommodation must be 'reasonably suitable'.
In judging the conduct of the landlord the real question is whether he has acted honestly or was inspired by some ulterior motives : see Chandraleka v. P.K. Suseela Rani, 1969 Rcr 572.
