Police Power vs Eminent Domain
The power of eminent domain is the inherent right of the state (and of those entities to which the power has been lawfully delegated) to condemn private property to public use upon payment of just compensation. On the other hand, police power is the power of the state to promote public welfare by restraining and regulating the use of liberty and property. Although both police power and the power of eminent domain have the general welfare for their object, and recent trends show a mingling of the two with the latter being used as an implement of the former, there are still traditional distinctions between the two.
Property condemned under police power is usually noxious or intended for a noxious purpose; hence, no compensation shall be paid. Likewise, in the exercise of police power, property rights of private individuals are subjected to restraints and burdens in order to secure the general comfort, health, and prosperity of the state. Thus, an ordinance prohibiting theaters from selling tickets in excess of their seating capacity (which would result in the diminution of profits of the theater-owners) was upheld valid as this would promote the comfort, convenience and safety of the customers
A thorough scrutiny of the extant jurisprudence leads to a cogent deduction that where a property interest is merely restricted because the continued use thereof would be injurious to public welfare, or where property is destroyed because its continued existence would be injurious to public interest, there is no compensable taking. However, when a property interest is appropriated and applied to some public purpose, there is compensable taking.
According to noted constitutionalist, Fr. Joaquin Bernas, in the exercise of its police power regulation, the state restricts the use of private property, but none of the property interests in the bundle of rights which constitute ownership is appropriated for use by or for the benefit of the public. Use of the property by the owner was limited, but no aspect of the property is used by or for the public. The deprivation of use can in fact be total and it will not constitute compensable taking if nobody else acquires use of the property or any interest therein.
If, however, in the regulation of the use of the property, somebody else acquires the use or interest thereof, such restriction constitutes compensable taking.
