- Sebastian represented the buyer of a commercial property in a high-court case, where the buyer demanded a proportionate reduction of the purchase price due to the seller’s incorrect information on pending rental cases as part of the due diligence process. The Eastern High Court ruled in full favour of the buyer, as the information was to be considered a warranty not subject to the buyer's duty of inspection.
