Short answer. Yes. Article 1747 of the Civil Code says that if a common carrier, without just cause, delays transporting the goods or changes the stipulated or usual route, it cannot rely on a contract limiting its liability for loss, destruction, or deterioration of the goods. An unjustified detour or delay strips away that protection.
What the law says
If the common carrier, without just cause, delays the transportation of the goods or changes the stipulated or usual route, the contract limiting the common carrier's liability cannot be availed of in case of the loss, destruction, or deterioration of the goods.

What Article 1747 takes away
Article 1747 provides that if the common carrier, without just cause, delays the transportation of the goods or changes the stipulated or usual route, the contract limiting the common carrier's liability cannot be availed of in case of the loss, destruction, or deterioration of the goods. A courier that normally caps what it owes you for a lost or damaged package loses the benefit of that cap if it delayed or rerouted your shipment without a good reason.
Two separate triggers, either one is enough
The article names two distinct acts — delays the transportation and changes the stipulated or usual route — and either one, done without just cause, is sufficient on its own to defeat the liability limit. You do not need to show both a delay and a detour; an unexplained change of route by itself, even without added delay, already falls within what the article addresses.
The "without just cause" qualifier
This is not an absolute rule against any deviation. A route change or delay caused by road closures, weather, security concerns, or other legitimate operational reasons is not what Article 1747 targets — the article is aimed at delays or detours that lack justification. Whether a particular deviation had "just cause" depends on the courier's actual reason for it, which is a factual question in each case.
Note also what the article strips away and what it leaves standing. It disables the contract limiting liability; it does not by itself decide that the courier is liable. You still have to show that the goods were lost, destroyed or deteriorated while in the carrier's hands. What Article 1747 does is remove the ceiling, so that if liability is established it is measured by the actual loss rather than by whatever figure the waybill printed on the back.
What to gather if this happened to you
Tracking records showing the shipment's actual route and timeline compared to what was promised, any explanation the courier gave for the delay or detour, and documentation of the loss or damage to your goods are what establish this claim. If the courier points to its liability limit, that tracking record is what a lawyer would use to test whether Article 1747 removes the limit in your case.
One threshold question comes first: the article speaks of a common carrier, meaning someone who offers carriage to the public as a business. A neighbour who agreed to drive your boxes to Batangas as a favour is not covered, and the extraordinary diligence that Article 1733 demands of common carriers does not apply to him either. Establishing that the courier holds itself out to the public is therefore the first thing to settle, before the detour or the delay matters at all.
