Agent Liability for Breach of Mandate in Real Estate Transaction

A dispute arose concerning the liability of an agent for damages incurred by a principal due to the agent's failure to execute a mandate, specifically relating to a real estate transaction where the agent neglected to secure the best possible price despite instructions. The Court of Cassation upheld the lower court's finding, reasoning that the agent breached the duty of care inherent in the mandate by failing to demonstrate that they had taken all necessary steps to obtain the most favorable conditions for the principal, thus confirming the agent's liability for the resulting prejudice.
