Sale Nullity Rejected Due to Implied Authority to Sell

A litigant sought the nullity of a sale of an immovable property, alleging that the notarized deed was invalid due to the agent of one of the parties lacking the necessary and expressly mentioned power of attorney, specifically arguing that the mandate did not explicitly authorize the sale. The court rejected the appeal, reasoning that although the mandate did not expressly mention the power to sell, the authority to sell was implicitly included in the general power granted to the agent to manage and conclude all acts necessary for the proper administration of the property, which encompasses the power to alienate it, thereby validating the transaction executed by the agent.
