In 1989 P took a loan of Rupees twelve hundred from B and executed usufructuary mortgage deed in this regard. The mortgage was for 9 years and the condition was that P shall not sell or mortgage the property in this period of nine years and that if he chose to sell the property he was required to give B the right of first refusal. The stipulation thus created a right of pre-emption in favor of B. Is it a clog on P’s right of redemption? Discuss.      (5 marks)
