[23] The Court is not a trier of facts and is not to reassess the credibility and probative weight of the evidence of the parties and the findings and conclusions of the Labor Arbiter and the NLRC as affirmed by the appellate court. Moreover, the factual findings of the Labor Arbiter and the NLRC are accorded respect and finality when supported by substantial evidence, which means suchevidence as that which a reasonable mind might accept as adequate to support a conclusion. The Court does not substitute its own judgment for that of the tribunal in determining where the weight of evidence lies or what evidence is credible.[24]   In the instant case, the CA, the NLRC and the Labor Arbiter are one in their findings that based on the evidence on record, petitioner is not entitled to disability benefits.   cralawPrescinding from the foregoing, the Court finds and so rules that under the Standard Terms and Conditions Governing the Employment of Filipino Seafarers On-Board Ocean-Going Vessel or the POEA Standard Employment Contract issued pursuant to DOLE Department Order No. 4, and POEA Memorandum Circular No. 9, both Series of 2000, petitioner is not entitled to disability benefits.
