Standard of Care
A common carrier is bound, by the nature of its business and by public policy, to observe extraordinary diligence in the vigilance over goods and in the safety of passengers. This duty attaches because the carrier holds itself out to the public as ready to transport persons or property for compensation, and the public must be able to rely on its skill, equipment, supervision, and operational control.
Extraordinary diligence is more exacting than the diligence of a good father of a family. For passengers, the Civil Code describes the duty as safe carriage as far as human care and foresight can provide, using the utmost diligence of very cautious persons, with due regard for all circumstances. For goods, it requires active vigilance from receipt to delivery, including proper handling, loading, custody, routing, stowage, protection, and timely delivery.
The standard is objective and contextual. The carrier must anticipate risks normally incident to the kind of transportation undertaken, the nature of the goods, the route, the weather, the condition of the vehicle or vessel, the volume of passengers or cargo, and the hazards that reasonably prudent operators in the same business should foresee.
Nature of Extraordinary Diligence
Extraordinary diligence does not make the carrier an absolute insurer against every conceivable loss, injury, or delay. It does, however, place on the carrier a heavy duty to prevent avoidable harm and to explain losses occurring while the passenger or goods are under its control.
The duty includes the obligation to provide safe and suitable vehicles, vessels, aircraft, machinery, appliances, terminals, and procedures. It also includes the obligation to employ competent personnel, enforce operational rules, monitor foreseeable dangers, and respond promptly when danger arises during the undertaking.
The carrier's control over transportation is the reason for the strict standard. Passengers normally surrender control over their movement, and shippers normally surrender custody over their goods; the carrier therefore bears the burden of maintaining safety in the portions of the operation under its direction.
| Subject | Required diligence | Immediate legal effect of loss or injury |
|---|---|---|
| Goods accepted for carriage | Extraordinary diligence in custody, preservation, carriage, and delivery | Loss, destruction, or deterioration raises a presumption that the carrier was at fault or failed to exercise the required diligence, unless the carrier proves a legally recognized cause and its own due care. |
| Passengers | Utmost diligence of very cautious persons, as far as human care and foresight can provide | Death or injury of a passenger raises a presumption of negligence, and the carrier must overcome that presumption by proof of extraordinary diligence or by showing that the harm was caused by a matter for which it is not legally responsible. |
| Checked baggage | Generally treated as goods placed in the carrier's custody | The carrier must account for loss or damage while the baggage is under its custody, subject to valid valuation rules and legally recognized limitations. |
| Hand-carried items | Linked to passenger safety and to the carrier's control over its premises and vehicle | The carrier is not automatically liable for every loss under the passenger's personal custody, but it remains liable when its lack of required care contributes to the loss or injury. |
Commencement and Termination of the Duty
For goods, extraordinary diligence begins when the goods are unconditionally placed in the possession of the carrier and accepted for transportation. A mere inquiry, booking, quotation, or incomplete tender does not yet place the goods under the carrier's vigilance.
The duty continues until actual or constructive delivery to the consignee or to the person entitled to receive the goods. Constructive delivery requires acts that place the goods at the disposal of the proper recipient in the manner contemplated by the contract, usage, or law, not merely the arrival of the vehicle at destination.
Temporary storage, unloading, transshipment, or custody incidental to transportation does not by itself end the carrier's extraordinary duty. If the storage or stop is part of the transportation undertaking or is necessary to complete delivery, the carrier remains bound by the standard applicable to common carriers.
For passengers, the duty begins when the passenger places himself or herself in the care of the carrier for the purpose of boarding or being transported, and the carrier accepts or is bound to accept that person as a passenger. The duty is not limited to the period when the vehicle is in motion.
The duty covers boarding, carriage, and alighting when these acts occur in areas and under circumstances controlled by the carrier. It ordinarily continues until the passenger has had a reasonable opportunity to leave the carrier's vehicle and premises safely.
Presumption of Negligence and Burden of Proof
When goods are lost, destroyed, or deteriorated while in the carrier's custody, the law presumes that the carrier was negligent or failed to exercise extraordinary diligence. The shipper or consignee generally need not prove the precise negligent act; proof of delivery to the carrier, failure to return or deliver in proper condition, and the resulting damage is enough to call for the carrier's explanation.
When a passenger dies or is injured in the course of carriage, the law likewise presumes that the carrier was negligent. The passenger or heirs generally establish the contract of carriage, the injury or death, and the connection of the harm with the carriage; the burden then shifts to the carrier to prove that it exercised the required diligence or that the cause was legally outside its responsibility.
The presumption is rebuttable, but it is not overcome by general statements that the vehicle was inspected, that employees were trained, or that usual procedures existed. The carrier must present concrete facts showing that the particular risk was addressed with the degree of care demanded by the circumstances.
The defense of diligence in the selection and supervision of employees, which may be relevant in other forms of liability, does not by itself defeat a passenger's claim based on breach of the contract of carriage. In passenger carriage, the carrier undertakes safe transportation, and the acts or omissions of its employees in performing that undertaking are treated as acts for which the carrier answers.
Goods: Legally Recognized Causes of Loss
For goods, the carrier may avoid liability when the loss, destruction, or deterioration was caused by a recognized exempting cause and the carrier proves that it still exercised the diligence required by law to prevent, lessen, or avoid the damage. The recognized causes include natural disasters or calamities, acts of a public enemy in war, acts or omissions of the shipper or owner, the character of the goods or defects in packing or containers, and acts or orders of competent public authority.
A natural disaster or calamity must be the proximate and adequate cause of the loss. If the carrier's defective equipment, poor stowage, unsafe routing, unreasonable delay, or failure to take precautions concurred with the event, the carrier remains liable because the loss is no longer due solely to the exceptional event.
An act of a public enemy refers to hostile acts by forces with whom the Philippines is at war or by comparable armed forces in civil conflict. Ordinary theft, pilferage, hijacking, or robbery is not automatically an act of public enemy, and the carrier must show that the event was irresistible or that it exercised extraordinary diligence against the foreseeable risk.
An act or omission of the shipper may relieve the carrier only when it is the proximate cause of the loss. Improper packing, inaccurate declarations, concealment of dangerous character, or instructions that create the risk may affect liability, but the carrier remains liable if the defect was apparent or if the carrier accepted the goods despite a risk it could reasonably detect and address.
The inherent nature of the goods may explain deterioration when the goods are naturally perishable, fragile, volatile, or susceptible to ordinary wastage. The carrier must still use appropriate methods of handling, ventilation, refrigeration, segregation, or protection when those measures are reasonably required by the nature of the cargo and the undertaking accepted.
An act or order of competent public authority may excuse non-delivery or delay when it directly prevents carriage or delivery, such as a lawful seizure, quarantine, embargo, or traffic order. The carrier must still show that it complied because it was legally bound to do so and that it did not contribute to the situation by its own fault.
Passengers: Safety as the Controlling Obligation
In passenger carriage, the controlling obligation is not merely to transport the passenger to the destination, but to transport the passenger safely. The carrier breaches the contract when its failure to exercise the required diligence causes injury, even if the fare was low, the trip was short, or the passenger reached the destination.
The duty covers foreseeable hazards inside the vehicle, at boarding and alighting points, and in carrier-controlled areas used as part of the transportation service. It includes preventing overloading, unsafe boarding, premature movement, reckless operation, defective doors or steps, inadequate crowd control, and other conditions that expose passengers to unreasonable danger.
The carrier is liable for injuries caused by the negligence or willful acts of its employees in connection with the carriage, even when the employee acted contrary to company rules or beyond express instructions. Internal rules do not reduce the standard owed to passengers; they are relevant only insofar as they show what precautions were required and whether those precautions were actually enforced.
Acts of strangers or co-passengers do not automatically make the carrier liable. Liability arises when the carrier's employees, through the required diligence, could have prevented or stopped the harmful act, or when the danger was foreseeable from the circumstances and the carrier failed to take reasonable protective measures consistent with extraordinary diligence.
A passenger's own negligence may reduce recovery when it contributes to the injury. If the passenger's act is the sole proximate cause of the harm, the carrier may be relieved; if the carrier's breach also contributes, the passenger's negligence generally affects the amount of damages rather than the existence of breach.
Stipulations Affecting the Standard
The law treats stipulations limiting a common carrier's responsibility with caution because the duty of extraordinary diligence is imposed by public policy, not merely by private agreement. Notices printed on tickets, receipts, bills of lading, posters, or websites do not automatically bind the passenger or shipper to a lower standard.
For passengers, the carrier cannot validly dispense with or diminish the duty to carry safely by stipulation, notice, or condition printed on a ticket. The passenger's acceptance of a ticket is not consent to waive the carrier's legal duty to use the utmost diligence required for safe transportation.
For goods, a limitation that reduces the carrier's liability below extraordinary diligence may be valid only when it is in writing, signed by the shipper or owner, supported by consideration other than the mere transportation service, and reasonable, just, and consistent with public policy. Even then, the carrier cannot reduce its responsibility below the diligence of a good father of a family or exempt itself from liability for its own negligence or that of its employees.
Valuation clauses, released-value rates, and declared-value requirements may be valid when fairly agreed upon and when the shipper is given a real opportunity to declare a higher value and pay the corresponding rate. Such clauses regulate recoverable amount; they do not license careless carriage.
A stipulation that the goods travel entirely at the owner's risk, that the carrier is not liable for any loss or damage, that the carrier need not observe any diligence, or that the carrier is not responsible for employee acts is contrary to the public nature of common carriage. A carrier may manage risk by lawful rates and reasonable conditions, but it may not erase the minimum legal standard.
Operational Applications
Extraordinary diligence requires the carrier to match precautions to the known risks of the service. A bus operator must maintain safe brakes, tires, lights, doors, steps, and driver conduct; a shipping line must provide seaworthy vessels, proper stowage, competent crew, and safe loading; an air carrier must observe procedures suited to aircraft safety, passenger handling, baggage custody, and weather-related risks.
The required diligence extends to contractors, agents, and substitutes used by the carrier when they perform parts of the transportation undertaking. A common carrier cannot avoid the statutory standard by delegating handling, terminal operations, delivery, or other integral functions to another person while continuing to hold itself out as responsible for the carriage.
Delay may evidence lack of diligence when it exposes goods or passengers to foreseeable harm or when it violates the reasonable time contemplated by the undertaking. Delay alone is not always equivalent to loss of diligence, but unexplained or avoidable delay that causes damage is treated as a breach of the carrier's obligation.
Equipment failure is not automatically a fortuitous event. Mechanical defects, tire bursts, brake failure, engine trouble, steering malfunction, or vessel unseaworthiness ordinarily require proof that the defect could not have been discovered or prevented despite the level of inspection, maintenance, and operation demanded of a common carrier.
Weather conditions do not by themselves excuse the carrier. The carrier must prove that the weather event was of such character that human care and foresight could not prevent the harm, and that it took appropriate precautions such as suspending travel, rerouting, securing cargo, warning passengers, or delaying departure when required by safety.
Compliance with minimum administrative regulations does not necessarily prove extraordinary diligence. Regulatory compliance may be evidence of care, but the Civil Code standard may demand more when the circumstances show that additional precautions were reasonably necessary for passenger safety or cargo protection.
Effect of Breach
Failure to exercise the required diligence constitutes breach of the contract of carriage and may also give rise to other civil consequences when the facts support them. The injured passenger, shipper, consignee, or other proper claimant may recover damages that are the natural and probable consequence of the breach, subject to rules on causation, mitigation, valuation, and contributory fault.
For goods, liability commonly covers the value of the goods lost, destroyed, or deteriorated, together with damages legally recoverable under the circumstances. Valid declared-value or released-value arrangements may affect the amount recoverable, but they do not defeat liability produced by the carrier's failure to meet the required standard.
For passengers, recoverable damages may include compensation for injury or death and other damages allowed by civil law when the facts justify them. When the carrier's conduct shows bad faith, gross negligence, or wanton disregard of passenger safety, the consequences may extend beyond ordinary compensatory liability.
The central inquiry remains whether the carrier exercised the diligence that the law demands from one who undertakes public transportation. Because common carriage involves public reliance and carrier control, doubts created by unexplained loss, injury, or unsafe operation are generally resolved against the carrier that failed to give a satisfactory account of its performance.
