Commercial Use of Machinery Constitutes Deemed Acceptance
Sale of Goods Act, 1930 — Sections 42, 55 & 59 (Statutory Doctrine)
Under Section 42, a buyer is deemed to have accepted delivered machinery when they intimate acceptance, perform any act in relation to it inconsistent with the seller's ownership (such as running the equipment in commercial production), or retain it beyond a reasonable period without rejecting it. Under Section 59, once deemed acceptance occurs, the buyer cannot reject the machinery or withhold the balance price, and is restricted to proving quantifiable damages for any alleged breach of warranty.
