Step 1: Understanding the Question:
The question asks whether a seller's silence regarding a known defect in an item (an unsound horse) sold at an auction constitutes "fraud" under the Indian Contract Act, 1872.
Step 2: Key Legal Principles and Approach:
The definition of fraud and the legal effect of silence are governed by Section 17 of the Indian Contract Act, 1872.
Specifically, the Explanation to Section 17 outlines when silence can or cannot amount to fraud.
Step 3: Detailed Explanation:
• General Rule of Caveat Emptor: In contracts of sale, the rule of caveat emptor (let the buyer beware) generally applies.
• The seller is not under a general legal obligation to disclose every single defect in the goods to the buyer.
• Section 17 Explanation on Silence: The Explanation to Section 17 states: "Mere silence as to facts likely to affect the willingness of a person to enter into a contract is not fraud, unless the circumstances of the case are such that, regard being had to them, it is the duty of the person keeping silence to speak, or unless his silence is, in itself, equivalent to speech."
• Analysis of the Scenario: In an ordinary auction sale, there is no fiduciary relationship between the seller (Ali) and the buyer (Bibi), and it is not a contract of utmost good faith (uberrimae fidei).
• Therefore, Ali has no statutory duty to speak or disclose the unsoundness of the horse.
• Ali's passive silence does not amount to active concealment or fraud, unless Bibi specifically asks him about the horse's health (which would trigger a duty to speak honestly), or if Ali stood in a fiduciary relation to Bibi (such as being her father/guardian, as shown in another statutory illustration).
• Since none of these special circumstances are mentioned, Ali's mere silence is not fraud.
• Thus, Option (D) is the correct answer.
Step 4: Final Answer:
According to the Explanation to Section 17 of the Act, mere silence is not fraud unless there is a duty to speak or silence is equivalent to speech, making Option (D) the correct answer.
