In Bi-Metallic Investment Co. v. State Board, 239 U.S. 441 (1915), a suit was brought by a taxpayer and landowner to enjoin a Colorado Board from putting in effect an order which increased the valuation of all taxable property in Denver 40 per cent. Such action, it was alleged, violated the Fourteenth Amendment as the plaintiff was given no opportunity to be heard. Mr. Justice Holmes, speaking for the Court, stated, p. 445: "Where a rule of conduct applies to more than a few people it is impracticable that every one should have a direct voice in its adoption. The Constitution does not require all public acts to be done in town meeting or an assembly of the whole. General statutes within the state power are passed that affect the person or property of individuals, sometimes to the point of ruin, without giving them a chance to be heard. Their rights are protected in the only way that they can be in a complex society, by their power, immediate or remote, over those who make the rule."
