This document discusses several inherent powers of the state, including the police power, power of expropriation, and power of taxation. It provides characteristics and limitations for each power. The police power allows the government to enact and enforce laws regulating public order and welfare. It is considered the most pervasive and demanding power. The power of expropriation refers to the power to take private property for public use, with necessity and just compensation. Finally, the power of taxation gives the government the ability to impose and collect revenues to fund operations, with the Bureau of Internal Revenue responsible for tax collection, assessment, and imposition.
