The Labor Arbiter saw no need to conduct formal hearings. He found that Bastol was healthy when deployed in December 1995 but subsequently contracted or suffered heart ailment during his period of employment with OSCI and PSL. He also found that Bastol did not show any appreciable improvement despite treatment by the company-designated physician, thus ruling that the fact that Dr. Lim had not issued a certification as to Bastol’s condition did not negate his claim for disability indemnity, as the determination of the degree thereof by Dr. Vicaldo of the Philippine Heart Center sufficed.   OSCI immediately assailed the above Labor Arbiter decision before the NLRC.21[21] Subsequently, on July 30, 1999, the NLRC issued a Resolution22[22] in NLRC NCR CA No. 019238-99, vacating and setting aside the January 28, 1999 Decision of the Labor Arbiter and remanding the case back to the Labor Arbiter for further proceedings, the dispositive portion ordering, thus:   WHEREFORE, for the reasons [above discussed], the decision appealed from is hereby vacated and set aside and the records of this case Remanded to the Labor Arbiter of origin for conduct of further approximate proceedings and to terminate the same with dispatch.   SO ORDERED.23[23] 21[21] Id. at 79-88, Notice of Appeal with Memorandum of Appeal, dated March 9, 1999. 22[22] Id. at 90-96, per Presiding Commissioner Rogelio I.
