G.R. No. 164684-85 - Philippine Long Distance Telephone Co., Inc. vs. Tiamson

On April 16, 1986, Philippine Long Distance Telephone Company, Inc. (PLDT) employed Antonio Q. Tiamson as a Radio Technician II (JG4) at its North Luzon Toll Network Division, Clark Transmission Maintenance Center (Clark-TMC) in Pampanga.
After the probationary period, Tiamson’s appointment was made regular for the same position.

On July 29, 1994, a letter from Anthony Dy Dee, President of the Angeles City Telephone System and Datelcom Corporation, alleged that PLDT employees at Clark-TMC were colluding with local subscribers to effect illegal overseas calls.
Acting on the complaint, PLDT dispatched a team from its Quality Control and Inspection Department (QCID) and Security Division for surveillance and investigation.

On August 2, 1994, Vidal Busa, a radio technician, was caught in flagrante delicto while monitoring an illegally connected overseas call using PLDT’s radio facilities.
The QCID obtained a printout of the CAMA tape showing 469 fraudulent overseas and local calls completed at the PLDT Clark-TMC Radio Room between July 29 and August 2, 1994.
Three overseas calls to Saudi Arabia on August 1, 1994 were imputed to Tiamson, whose duty hours (allegedly from 10:00 p.m. to 6:00 a.m.) were recorded.

In his initial investigation, Busa admitted his own involvement and implicated Arnel Cayanan (shift supervisor), Antonio Tiamson, and Paul Cruzada.
During a subsequent confrontation on August 3, 1994, Busa reiterated that Tiamson was involved in connecting illegal overseas calls.
Tiamson admitted his technical knowledge of making overseas calls through operating manual study and experimentation but denied personal involvement in any illegal connection, claiming he even disconnected illegal calls made by Busa.
Tiamson further explained that he did not report Busa’s actions because Busa was his supervisor and he was fearful of antagonizing him.

On August 5, 1994, further confrontations led to additional testimonies by Busa and Cruzada, who confirmed encounters with ongoing illegal connections.
PLDT, after an internal investigation, issued an Inter-Office Memorandum on August 12, 1994, charging Tiamson with violating company rules and requiring him to explain why he should not be dismissed.
Tiamson was placed under preventive suspension on August 16, 1994 and submitted his written explanation on August 18, 1994 denying involvement.
PLDT found his explanation unsatisfactory and terminated his employment effective October 7, 1994, on the ground of serious misconduct and/or fraud.

Tiamson filed a complaint for illegal suspension, dismissal, and damages (NLRC Case No. RAB-III-07-6414-95).
The Labor Arbiter ruled in favor of Tiamson, ordering his reinstatement with full backwages and awarding attorney’s fees, while dismissing claims for moral and exemplary damages.
The NLRC later held that while just cause for dismissal existed, dismissal was too harsh, and thus ordered reinstatement without backwages.
Both PLDT and Tiamson elevated the case to the Court of Appeals (CA) under consolidated petitions (CA-G.R. SP Nos. 51855 and 52247).

On April 16, 2004, the CA reinstated the Labor Arbiter’s decision in its entirety, giving due course to Tiamson’s petition and denying PLDT’s petition.
The CA found that Busa’s sworn statement was not credible, noting inconsistencies regarding the timing of shifts which made it impossible for him to have observed Tiamson making illegal connections.
The CA also noted a due process defect in that Tiamson was not given the opportunity to refute the charge regarding the three overseas calls recorded on the CAMA tape.
PLDT filed a motion for reconsideration before the CA, which was denied on July 27, 2004, after which the petitioner elevated the matter to the Supreme Court on certiorari.

Whether the evidence was sufficient to establish that Tiamson was involved in the illegal connection of overseas calls, thereby justifying his dismissal.
Whether the employer (PLDT) complied with the requisite procedural due process in informing Tiamson of the specific evidence against him, particularly the charge based on the CAMA tape recording.
The credibility and admissibility of the key evidence, notably the sworn statements of Vidal Busa and the unauthenticated CAMA tape printout.
Whether the dismissal of Tiamson was legal and just, considering the findings of various tribunals (Labor Arbiter, NLRC, and Court of Appeals) and the nature of the evidence presented.
