Does the TP Act apply to a lease executed prior to the extension of that Act to the area, even though the event that determines the tenancy viz., forfeiture, occurs after such extension ? Secondly, if the TP Act does not apply proprio vigore to such demises and their determination, can the principles of justice, equity and good conscience be invoked to transplant the twin rules in section 111(g) of the said Act? Thirdly, and this is the crux of the matter if such transfusion is permissible, 913 is the synergetic operation of breach of a condition of the lease providing for re entry and a written notice of forfeiture on that score obligatory in terms of section 111(g) or can written notice of forfeiture be dispensed with as being no part of equity or justice but a technical or formal statutory requirement? What, in short, is the status of the formula of justice, equity and good conscience, in the legal pharmacopoeia of India? Shri A. K. Sen urges that the procedural interdict against raising the objection based on section 111(g) is of no consequence.
