Dioscoro is the sole stockholder and nominee of Dalisay Food Products OPC (DFP OPC), a One Person Corporation that manufactures and distributes bottled condiments. DFP OPC incurred debts of PHP 8 million to various suppliers. When DFP OPC became insolvent, its suppliers sued Dioscoro personally for the PHP 8 million corporate debt, arguing that as the sole stockholder, officer, and decision-maker of DFP OPC, Dioscoro was personally running the corporation as if it were his individual enterprise and should be held liable for its debts. In his defense, Dioscoro invoked the separate juridical personality of DFP OPC and denied personal liability. Dioscoro maintained all corporate formalities, kept separate corporate books, and never commingled corporate and personal funds. Is Dioscoro personally liable for the debts of DFP OPC?
