Facts:
Juan Perez et al is a usufructuary of a parcel of land. The usufructuaries entered into a contract leasing the fishpond to Luis Keh . Paragraph 5 of the lease contract states that the lessee cannot sublease the fishpond nor assign his rights to anyone.
Ming Cosim and Luis Crisostomo two persuaded private respondent to take over the operation of Papaya Fishpond as petitioner Lee and his partner, petitioner Luis Keh, were allegedly losing money in its operation. Private respondent having acceded to the proposal, he and petitioners Lee and Keh executed a written agreement denominated as pakiao buwis whereby private respondent would take possession of the Papaya Fishpond.
Issue:
Whether or not, Luis Keh is liable for breach of contract under Article 1168.
Ruling:
Article 1168 of the Civil Code provides that when an obligation consists in not doing and the obligor does what has been forbidden him, it shall also be undone at his expense. The lease contract prohibited petitioner Luis Keh, as lessee, from subleasing the fishpond. In entering into the agreement for pakiao-buwis with private respondent, not to mention the apparent artifice that was his written agreement with petitioner Lee on January 9, 1978, petitioner Keh did exactly what was prohibited of him under the contract to sublease the fishpond to a third party.
That the agreement for pakiao-buwis was actually a sublease is borne out by the fact that private respondent paid petitioners Luis Keh and Juan Perez, through petitioner Tansinsin the amount of annual rental agreed upon in the lease contract between the usufructuaries and petitioner Keh. Petitioner Keh led private respondent to unwittingly incur expenses to improve the operation of the fishpond. By operation of law, therefore, petitioner Keh shall be liable to private respondent for the value of the improvements he had made in the fishpond or for P486,562.65 with interest of six percent (6%) per annum from the rendition of the decision of the trial court on September 6, 1989.
