4/10/2020 E-Library - Information At Your Fingertips: Printer Friendly reasonable mind might accept as adequate to support a conclusion, even if other equally reasonable minds might conceivably opine otherwise.[33] To our mind, Calawigan’s unsubstantiated assertion that he requested for a post-employment medical examination from LISI does not even come close to approximating the foregoing quantum of proof. Given that compliance with said requirement is mandatory and the unexplained omission thereof will bar the filing of a claim for disability benefits, [34] the CA clearly erred when it adjudged Calawigan entitled to sickness allowance and permanent disability compensation despite his failure to abide by the procedure outlined under the POEA-SEC. As it would be fairly easy for a physician to determine whether the injury or ailment is work-related within three-days from repatriation, to ignore the requirement would set a precedent with negative repercussions which would open the floodgates to a limitless number of seafarers claiming disability benefits.[35] Even if we were to disregard the fact, however, that the POEA-SEC recognizes only the disability grading provided by the company-designated physician,[36] LISI correctly faults the CA for awarding disability benefits corresponding to the Grade 3 disability rating assessed by Dr. Mendiola. The record shows that on 5 July 2005, Dr. Mendiola issued the following medical certificate in favor of Calawigan, to wit: This is to certify that Mr. Enrique Calawigan, 46 years old, was seen and examined by the undersigned last June 26, 2005 due to hearing impairment on both ears. Pure tone audiometry was requested which revealed moderate bilateral sensorineural hearing loss (Grade 3). Tympanometry showed ossicular disarticulation on right ear; normal findings on left ear. This medical certificate was issued upon request for whatever purpose it may serve.[37] For an occupational disease and the resulting disability to be compensable, all of the following conditions must be satisfied under the POEA-SEC: (1) the seafarer’s work must involve the risks described in the contract; (2) the disease was contracted as a result of the seafarer's exposure to the described risks; (3) the disease was contracted within a period of exposure and under such other factors necessary to contract it; and (4) there was no notorious negligence on the part of the seafarer.[38] Deafness is listed as an occupational disease for work in “any industrial operation having excessive noise particularly in the higher frequencies” or “any process carried on in compressed or rarified air.”[39] Sec. 32 of the POEA-SEC assigns the following disability grades for ear injuries or ailments, viz.: SECTION 32.
