The PDIC vigorously pursues legal actions against bank owners, officials and personnel who engage in unsafe and unsound banking practices that pose grave threats to the stability of the country's banking system. Republic Act 3591, as amended, or the PDIC Charter mandates the PDIC to strengthen the mandatory deposit insurance coverage system to generate, preserve and maintain confidence in the stability of the banking system as well as protect it from illegal schemes and machinations. In relation to its mandates, the PDIC is authorized to conduct investigations and file necessary cases against erring bank officials and unscrupulous individuals.
