In his Comment,[17] the respondent claims that the company-designated physician had no factual basis in ruling that his illness was not work-related. He posits that the opinions of company-designated physicians should not be taken as gospel truth because of their non-independent nature. Finally, he claims that his illness could have only been acquired on board since he passed the company’s PEME.   THE COURT’S RULING             We find the petition meritorious.             The petitioners essentially claim that the evidence on record does not support the findings of the labor tribunals and the CA that the respondent’s illness was work-related.  This argument clearly involves a factual inquiry whose determination is not a function of this Court. We emphasize, however, that we are reviewing in this Rule 45 petition the decision of the CA on a Rule 65 petition filed by the petitioners with that court.  In so doing, we review the legal correctness of the CA decision from the prism of whether it correctly determined the presence or absence of grave abuse of discretion in the NLRC decision before it.             In this task, the Court is allowed, in exceptional cases, to delve into and resolve factual issues when insufficient or insubstantial evidence to support the findings of the tribunal or court below is alleged, or when too much is concluded, inferred or deduced from the bare and incomplete facts submitted by the parties, to the point of grave abuse of discretion.[18]  The present case constitutes one of these exceptional cases.   The Rule on Disability Benefits   Entitlement of seamen on overseas work to disability benefits is a matter governed, not only by medical findings, but by law and by contract.
