Purchaser's Claim for Nullity of Sale Due to Undisclosed Structural Defects Fails

A purchaser of a building, having discovered after the sale that the structure was afflicted with serious defects, including cracks indicating structural instability, sought the nullity of the sale and damages, arguing the seller was aware of these hidden defects and failed to disclose them. The court rejected the appeal, affirming that the seller's knowledge of the defects was not established; the mere fact that defects existed at the time of the sale did not automatically equate to the seller's fraudulent concealment, and the buyer failed to prove the seller was actively aware of and concealed these specific structural issues.
