Order passed by President against recommendations of Wafaqi Mohtasib whereby relief granted to petitioners by Wafaqi Mohtasib was withdrawn–Such order of President being in violation of principles of natural justice i.e., not affording opportunity of being heard to petitioner, was excluded from consideration–As far sale agreement, time was not the essence of contract–Delivery of possession of plot in question, having not been delivered to petitioner, he could not be expected to have complied with terms of agreement relating to payment of remaining/balance amount–Amount of specified interest demanded from petitioner was, thus, not warranted and the same was declared to be without lawful authority and of no legal effect
