G.R. No. 189486 ; September 5, 2012
SIMNY G. GUY, GERALDINE G. GUY, GLADYS G. YAO, and the HEIRS OF THE LATE GRACE G. CHEU, Petitioners, vs. GILBERT G. GUY, Respondent. (Consolidated with G.R. No. 189699)

FACTS

The case involves an intra-corporate dispute over the shareholdings in GoodGold Realty & Development Corporation. Respondent Gilbert G. Guy initially held 519,997 shares, representing nearly 80% of the subscribed capital. Petitioners, led by his mother Simny Guy, claimed that the corporation was a family business and that the shares were held by Gilbert in trust. In 1999, the aging patriarch, Francisco Guy, orchestrated a redistribution of shares to equally allocate them among the children, reducing Gilbert’s holding to 65,000 shares. New stock certificates were issued reflecting this change.
In 2004, Gilbert filed a complaint in the RTC of Manila to nullify the share transfers, alleging forgery of his signature on the endorsed stock certificates. He withdrew this complaint after the National Bureau of Investigation (NBI) submitted a report conclusively authenticating his and the corporate secretary’s signatures on the disputed certificates. In 2008, Gilbert filed a new, nearly identical complaint with the RTC of Mandaluyong, again seeking nullification of the share transfers and corporate documents, this time denying the very existence of the stock certificates and claiming his shares were never issued.

ISSUE

The core issue is whether the 2008 complaint filed by Gilbert constitutes a nuisance or harassment suit, barred by the principles of res judicata and forum shopping, warranting its dismissal.

RULING

The Supreme Court granted the petitions and ordered the dismissal of the 2008 complaint. The Court ruled that the complaint was a nuisance suit, constituting blatant forum shopping and violating the doctrine of res judicata in its concept of conclusiveness of judgment. The 2004 and 2008 complaints involved identical parties, the same subject matter (the validity of the share redistribution), and the same causes of action (declaration of nullity based on alleged defects in the stock certificates and corporate records). Gilbert’s withdrawal of the first case after receiving an adverse NBI report did not negate the application of res judicata by conclusiveness of judgment. This doctrine bars the re-litigation of facts and issues already directly adjudicated or necessarily involved in a prior action, even if no final judgment on the merits was rendered.
The Court found that Gilbert’s shift in theory—from alleging forgery in the first case to denying the certificates’ existence in the second—was a transparent attempt to circumvent the definitive NBI findings. Such a tactic is an abuse of the judicial process. By re-filing a suit grounded on the same fundamental controversy after failing to obtain a favorable result in his initial attempt, Gilbert engaged in forum shopping, which aims to secure a favorable opinion from another court. The Supreme Court emphasized that courts have the inherent power to dismiss nuisance suits that waste judicial resources and harass opponents. Consequently, the RTC-Mandaluyong was ordered to dismiss SEC-MC08-112 immediately.
