Burden of Proof in Cargo Shortage Claims: When Arrastre Operators Escape Liability

In cargo shortage claims, the burden of proof can determine the outcome of the case. The Supreme Court, in Asian Terminals, Inc. v. Simon Enterprises, Inc. (G.R. No. 177116, February 27, 2013), clarified that a claimant must first establish the actual weight of the shipment at the port of origin before the burden shifts to the carrier or arrastre operator to prove that it exercised extraordinary diligence. This ruling provides important guidance on the evidentiary requirements in shortage claims.

The Facts of the Case

Simon Enterprises, Inc. filed a claim for damages against Asian Terminals, Inc. (ATI), an arrastre operator, and the carrier of two shipments of U.S. Soybean Meal in bulk. Simon claimed it received less than what was manifested in the bills of lading. For the first shipment, Simon alleged a shortage of 18.556 metric tons; for the second, it claimed a shortage of 199.863 metric tons.

The Regional Trial Court and the Court of Appeals ruled in favor of Simon, holding ATI solidarily liable with the carrier. The courts found that Simon had established the shortage and that the defendants failed to prove they exercised extraordinary diligence. ATI appealed to the Supreme Court.

The Issue

The central issue was whether ATI, as arrastre operator, could be held solidarily liable for the alleged cargo shortage. ATI argued that Simon failed to prove that the shipment actually weighed 3,300 metric tons at the port of origin, and that the alleged shortage was within acceptable allowances.

The Ruling: Proving the Shortage First

The Supreme Court granted ATI's petition and dismissed the complaint against it. The Court emphasized that while common carriers are presumed negligent if goods are lost or deteriorated, the claimant must first establish that an actual shortage occurred. This requires proving, by a preponderance of evidence, the weight of the shipment at the port of origin and its weight at the port of arrival.

In this case, Simon failed to prove the actual weight of the cargo when it was loaded. The bill of lading contained a "Shipper's weight, quantity and quality unknown" clause, which means the carrier was oblivious to the actual weight of the cargo. The Court cited Malayan Insurance Co., Inc. v. Jardine Davies Transport Services, Inc. and Wallem Philippines Shipping, Inc. v. Prudential Guarantee & Assurance, Inc. to explain that such clauses make the shipper solely responsible for the declared weight.

The Court also noted that the Proforma Invoice allowed the shipper to ship 10% more or less than the contracted quantity. The alleged shortage of 199.863 metric tons was only 6.05% of the total shipment, well within this allowance.

The Weight of the Evidence

The Court found that the survey reports relied upon by Simon were unreliable. The barge displacement method used to determine the weight was merely an estimation based on the water displaced by the barges, not an actual weighing of the cargo. The surveys were conducted in slight to slightly rough sea conditions, which could affect accuracy.

Moreover, there were discrepancies in the computations. One exhibit used 52 kilos per bag while another inexplicably used 49 kilos per bag, resulting in a significant difference in the computed shortage. These inconsistencies undermined the credibility of Simon's claim.

The Court also noted that soybean meal tends to settle or consolidate over time and can lose moisture during transit. Given that the shipment had a moisture content of 12.5% and traveled for 36 days from wintertime Louisiana to warmer Manila, the cargo could have lost weight naturally.

Practical Takeaways

• Claimants must prove the actual weight at origin. A bill of lading with a "shipper's weight, quantity and quality unknown" clause is not conclusive proof of the cargo's weight. The claimant must present competent evidence of the actual weight loaded.
• The burden shifts only after a prima facie showing of shortage. The presumption of negligence against common carriers applies only after the claimant establishes that a loss or shortage actually occurred.
• Allowable tolerances matter. If the contract allows a certain percentage of variation in quantity, an alleged shortage within that tolerance may not give rise to a cause of action.
• Survey methods must be reliable. Cargo weight estimates based on displacement methods in poor sea conditions, or computations with unexplained discrepancies, may not satisfy the evidentiary standard.
• Arrastre operators are not automatically liable. An arrastre operator's liability depends on proof of negligence or fault, not merely on the fact that a shortage was alleged.
