As per case facts, the plaintiff purchased two flats in a public auction. The first defendant claimed ownership, leading to an agreement for the plaintiff to grant power of attorney ... for flat F2 in exchange for F1's possession and payment, but payment failed. The plaintiff revoked the power of attorney, but the first defendant still sold F2, leading to further transactions. The plaintiff sued for declaration and possession. The trial court granted partial relief for F1 but dismissed the suit for F2, leading to this appeal. The question arose whether the power of attorney's revocation was effectively communicated to all parties and if its registration constituted public notice. Finally, the High Court held that the revocation notice was not proven to be served on the first or second defendant. Also, prior to a 2012 amendment, registration of a power of attorney in Book No.4 was not public notice. Thus, the agency termination was not effective, validating F2's sale. The appeal was partly allowed, granting recovery of possession for F1, while confirming F2's suit dismissal.
