G.R. No. 170132, December 6, 2006
Government Service Insurance System (GSIS) and Winston F. Garcia vs. Kapisanan ng mga Manggagawa sa GSIS (KMG)

FACTS

In October 2004, GSIS rank-and-file employees, who were members of the respondent union KMG, participated in a four-day mass action, including rallies and a walkout, in front of the GSIS main office. The action, which also included contingents from other agencies, was directed at petitioner GSIS President Winston F. Garcia. While a local rally permit was allegedly issued, the participating GSIS employees did not have approved leaves for their absence.
Subsequently, the GSIS management issued show-cause memoranda and eventually filed formal administrative charges against hundreds of KMG members for grave misconduct and conduct prejudicial to the best interest of the service. KMG filed a Petition for Prohibition with the Court of Appeals, arguing the charges disregarded Civil Service guidelines on handling grievances. The CA granted the petition and perpetually enjoined Garcia from implementing the charges, ruling the filing was a grave abuse of discretion. The GSIS and Garcia elevated the case to the Supreme Court.

ISSUE

Whether the Court of Appeals correctly issued a writ of prohibition to perpetually enjoin the GSIS from pursuing administrative charges against its employees for participating in the mass action.

RULING

No. The Supreme Court reversed the CA decision and lifted the injunction. The Court held that the CA erred in granting the writ of prohibition, as no grave abuse of discretion attended the act of filing the administrative charges. The GSIS, as a government-owned and controlled corporation with an original charter, is part of the civil service. Its employees are therefore governed by civil service laws and rules, including CSC Resolution No. 021316, which explicitly prohibits government employees from engaging in concerted activities that cause work stoppage or service disruption, such as mass leaves and walkouts.
The act of filing administrative charges after a proper investigation into a prima facie violation of these civil service rules is a legitimate exercise of management’s prerogative and disciplinary authority. It is a function inherent to the GSIS President’s role, as mandated by its charter, to discipline personnel for cause in accordance with civil service regulations. The mere filing of charges, based on a reasonable belief that rules were violated, does not constitute grave abuse of discretion warranting the extraordinary writ of prohibition. The proper recourse for the charged employees was to exhaust administrative remedies and defend themselves in the ongoing disciplinary proceedings, not to seek judicial intervention to prematurely stop those proceedings.
