Work-Related Illness and Seafarers’ Disability Claims: Proving the Causal Link

The Supreme Court’s 2012 ruling in Casomo v. Career Philippines Shipmanagement, Inc. (G.R. No. 191606) clarifies a crucial point for seafarers seeking disability compensation: falling ill during a contract is not enough. The claimant must show a real connection between the work performed and the illness suffered. This article explains the ruling and its practical implications.

The Facts of the Case

Damaso Casomo was hired as an Able Seaman for a nine-month contract. After passing his pre-employment medical examination, he boarded the vessel in November 2005. In January 2006, he felt a lump on his right face. When the ship reached Japan, a doctor diagnosed a tumor of the right lower jaw with secondary cystic infection. Casomo was repatriated for further treatment.

In Manila, the company-designated physician diagnosed ameloblastoma—a serious impacted wisdom tooth condition—and performed surgery. The physician declared the illness not work-related. Casomo nonetheless claimed permanent disability benefits, arguing that because he fell ill during his employment, the illness was disputably presumed work-related under the POEA Standard Employment Contract.

The Legal Issue

The central question was whether Casomo was entitled to permanent disability benefits despite failing to show any causal connection between his work as an Able Seaman and his ameloblastoma.

The Ruling: Proof of Work-Relatedness Is Required

The Supreme Court denied Casomo’s claim. The Court held that the disputable presumption in Section 20(B)(4) of the POEA Standard Employment Contract—that illnesses not listed in Section 32 are presumed work-related—does not relieve the seafarer of the burden of proof.

The Court emphasized that a seafarer must demonstrate two things: (1) the illness is work-related, and (2) it existed during the term of the employment contract. Mere assertion that the illness developed during employment is insufficient.

The Standard of Proof: Probability, Not Certainty

The Court reiterated that the touchstone for work-relatedness is probability, not certainty. However, that probability must be founded on facts and reason. Casomo presented no evidence linking his duties as an Able Seaman—such as launching life-saving equipment or security inspections—to the development of ameloblastoma. His own research on the disease noted that its cause is not understood and mentioned no connection to seafaring work.

Why the PEME Does Not Help the Claim

The Court also addressed the argument that Casomo was declared “fit to work” before embarkation. A pre-employment medical examination is not exploratory. It does not guarantee that any illness contracted later is work-related. The PEME merely establishes fitness at the time of hiring.

Practical Takeaways

• Prove the link. A seafarer claiming disability benefits must present substantial evidence connecting the illness to job duties or risks. A bare allegation that the illness occurred during the contract will not suffice.
• The presumption is not automatic. Section 20(B)(4) creates a disputable presumption, but the claimant must still substantiate the claim with evidence of work causation or aggravation.
• Use the POEA schedule. For illnesses not listed in Section 32, the seafarer must satisfy the conditions in Section 32-A: the work involves the risk, the disease resulted from exposure, it was contracted within the exposure period, and there was no notorious negligence.
• Medical certification matters. A company-designated physician’s finding is not automatically biased. A claimant should obtain independent medical evidence that addresses work-relatedness, not just current disability.
• Consult a lawyer early. Disability claims involve technical rules of evidence and contract interpretation. Legal advice can help seafarers build the necessary record before filing.
