403 Phil. 340
QUISUMBING, J.:
"...on January 25, 1979, plaintiff-appellee [herein petitioner] Pablo U. Abella purchased an MF 210 agricultural tractor with Serial No. 00105 and Engine No. P126M00199 (Exhibit A; Record, p.5) which he used in his farm in Dagohoy, Bohol.On November 25, 1988, private respondent instituted an action for replevin, claiming ownership of the tractor and seeking to recover possession thereof from petitioner. As adverted to above, the trial court ruled in favor of private respondent; so did the Court of Appeals when petitioner appealed.
Sometime in October or November 1985, Pablo Abella's son, Mike Abella rented for residential purposes the house of defendant-appellant Dionisio R. Calibo, Jr., in Tagbilaran City.
In October 1986, Pablo Abella pulled out his aforementioned tractor from his farm in Dagohoy, Bohol, and left it in the safekeeping of his son, Mike Abella, in Tagbilaran City. Mike kept the tractor in the garage of the house he was leasing from Calibo.
Since he started renting Calibo's house, Mike had been religiously paying the monthly rentals therefor, but beginning November of 1986, he stopped doing so. The following month, Calibo learned that Mike had never paid the charges for electric and water consumption in the leased premises which the latter was duty-bound to shoulder. Thus, Calibo confronted Mike about his rental arrears and the unpaid electric and water bills. During this confrontation, Mike informed Calibo that he (Mike) would be staying in the leased property only until the end of December 1986. Mike also assured Calibo that he would be settling his account with the latter, offering the tractor as security. Mike even asked Calibo to help him find a buyer for the tractor so he could sooner pay his outstanding obligation.
In January 1987 when a new tenant moved into the house formerly leased to Mike, Calibo had the tractor moved to the garage of his father's house, also in Tagbilaran City.
Apprehensive over Mike's unsettled account, Calibo visited him in his Cebu City address in January, February and March, 1987 and tried to collect payment. On all three occasions, Calibo was unable to talk to Mike as the latter was reportedly out of town. On his third trip to Cebu City, Calibo left word with the occupants of the Abella residence thereat that there was a prospective buyer for the tractor. The following week, Mike saw Calibo in Tagbilaran City to inquire about the possible tractor buyer. The sale, however, did not push through as the buyer did not come back anymore. When again confronted with his outstanding obligation, Mike reassured Calibo that the tractor would stand as a guarantee for its payment. That was the last time Calibo saw or heard from Mike.
After a long while, or on November 22, 1988, Mike's father, Pablo Abella, came to Tagbilaran City to claim and take possession of the tractor. Calibo, however, informed Pablo that Mike left the tractor with him as security for the payment of Mike's obligation to him. Pablo offered to write Mike a check for P2,000.00 in payment of Mike's unpaid lease rentals, in addition to issuing postdated checks to cover the unpaid electric and water bills the correctness of which Pablo said he still had to verify with Mike. Calibo told Pablo that he would accept the P2,000.00-check only if the latter would execute a promissory note in his favor to cover the amount of the unpaid electric and water bills. Pablo was not amenable to this proposal. The two of them having failed to come to an agreement, Pablo left and went back to Cebu City, unsuccessful in his attempt to take possession of the tractor."[1]
"He who is not the owner or proprietor of the property pledged or mortgaged to guarantee the fulfillment of a principal obligation, cannot legally constitute such a guaranty as may validly bind the property in favor of his creditor, and the pledgee or mortgagee in such a case acquires no right whatsoever in the property pledged or mortgaged."[3]There also does not appear to be any agency in this case. We agree with the Court of Appeals that:
"As indicated in Article 1869, for an agency relationship to be deemed as implied, the principal must know that another person is acting on his behalf without authority. Here, appellee categorically stated that the only purpose for his leaving the subject tractor in the care and custody of Mike Abella was for safekeeping, and definitely not for him to pledge or alienate the same. If it were true that Mike pledged appellee's tractor to appellant, then Mike was acting not only without appellee's authority but without the latter's knowledge as well.There is likewise no valid deposit in this case. In a contract of deposit, a person receives an object belonging to another with the obligation of safely keeping it and of returning the same.[5] Petitioner himself states that he received the tractor not to safely keep it but as a form of security for the payment of Mike Abella's obligations. There is no deposit where the principal purpose for receiving the object is not safekeeping.[6]
Article 1911, on the other hand, mandates that the principal is solidarily liable with the agent if the former allowed the latter to act as though he had full powers. Again, in view of appellee's lack of knowledge of Mike's pledging the tractor without any authority from him, it stands to reason that the former could not have allowed the latter to pledge the tractor as if he had full powers to do so."[4]
