The eminent domain power exists in all countries. Although there is opposition to its exercise, it is neither confiscation nor an arbitrary treatment of individual property, but an inherent and long-standing prerogative of government. Whether it is equitable is determined not by its use per se but by the nature of the criteria governing public benefit and justness of compensation, by the reasonableness of the statute governing rights and duties, and by the exercise of official good faith in the proceedings.
