G.R. No. 8692 - Godofredo B. Herrera, as Municipal President of Caloocan, vs. Alberto Barretto, Judge of 1st Instance of Rizal, and Constancio Joaquin

Saturnino A. Elevera was employed as a 3rd Engineer on board the vessel "Normand Baltic" by respondent OSM Maritime Services, Inc. (OSM Maritime) for a three‐month contract with deployment on January 30, 2013.
His employment was on behalf of OSM’s foreign principal, OSM Crew Management, Inc., and he rendered 18 years of continuous service in engine rooms, where he was exposed to excessive noise and harmful chemicals.

In March 2013, Elevera experienced symptoms including a “ringing sensation” in his left ear, dizziness described as a swirling sensation, and hearing loss.
On March 18, 2013, he was brought to Changi General Hospital where he was diagnosed with “Ear-Vertigo and other Vestibular Disorder–Stress Related.”
Repatriated to the Philippines on March 21, 2013, he was evaluated by the company-designated physician, Dr. Karen Frances Hao-Quan, who noted a diagnosis including mild sensorineural hearing loss in the right ear, moderate sensorineural hearing loss in the left ear, vestibular neuronitis, hypertensive cardiovascular disease, and bilateral blepharitis.
On July 1, 2013, another company-designated doctor, Dr. Raymond L. Rosales, diagnosed him with vestibular neuronitis with intermittent headaches, tinnitus, and hearing loss, recommending a Grade 10 disability rating (indicating a slight brain functional disturbance with minimal interference with working capacity).
Subsequently, on August 30, 2013, Dr. Rosales issued a follow-up report diagnosing Elevera with Meniere’s Disease and declaring him permanently unfit for sea duties.

On September 27, 2013, Elevera filed a complaint before the Labor Arbiter (LA) seeking permanent total disability benefits, moral and exemplary damages, attorney’s fees, and reimbursement of medical expenses after OSM Maritime refused to pay the full benefits.
The LA dismissed his complaint on June 23, 2014, holding that he failed to establish a causal nexus between his work environment (engine room exposure) and the development or aggravation of his illness; the LA also questioned the sufficiency and timing of his personal medical evaluation.
Elevera then appealed the LA decision with the National Labor Relations Commission (NLRC).

On January 9, 2015, the NLRC granted Elevera’s appeal reversing the LA decision and awarded permanent disability benefits of US$60,000.00, declaring his illness as work-related.
The NLRC based its decision on the cumulative evidence of prolonged exposure to engine room noise and the conflicting medical evaluations, while rejecting the OSM Extended Insurance Manual due to the absence of supporting documents (such as proof of a collective bargaining agreement and union membership).
Later, in a Resolution dated May 15, 2015, the NLRC modified its decision to reduce the award to US$44,405.00 as partial disability benefits with a Grade 3 rating, highlighting that the nearest work-related illness was the total loss of hearing, an outcome corresponding to that rating.

Both Elevera and respondents elevated the case to the CA by filing petitions for certiorari, which were consolidated.
The CA Decision dated September 5, 2017 partially granted Elevera’s petition by awarding attorney’s fees at 10% of the judgment award but reduced the disability benefit to US$39,180.00 after finding an error in the NLRC’s computation multiplier.
The CA concurred with the NLRC on the work-relatedness of Elevera’s illness and affirmed a Grade 3 disability rating, while rejecting reliance on the OSM Extended Insurance Manual.
Elevera’s subsequent motion for reconsideration was denied by the CA Resolution dated May 31, 2018, prompting the present Petition for Review on Certiorari before the Supreme Court.

Whether the present Petition is dismissible on the ground that it is moot and academic due to Elevera’s receipt of the judgment award and execution of the NLRC Decision.
Whether the conditional settlement executed by the parties constitutes a final satisfaction of judgment that bars further relief.

Whether the CA committed reversible error in upholding the NLRC’s determination that Elevera is entitled only to disability benefits corresponding to a Grade 3 impediment rating (i.e., partial disability) as opposed to a declaration of “permanent total disability.”
Whether, notwithstanding the findings of the NLRC and CA, Elevera’s medical condition—as evidenced by multiple medical reports—should be regarded as a total disability.

Whether the CA erred in refusing to apply the provisions of the OSM Extended Insurance Manual, which would otherwise entitle Elevera to a higher disability benefit (up to US$150,000.00).
Whether Elevera satisfied the evidentiary requirements (including union membership and submission of a valid collective bargaining agreement) to avail himself of such increased benefit.
