In the Virginia Supreme Court case of Moss versus County of Tazewell, the decision stated that "the power of the legislature of the State is supreme, except so far as it is restrained by State or Federal Constitution." Therefore, a State constitution is usually considered as a restraining agreement whereby the Federal Constitution is considered as a granting agreement. Thus, the legislative body of a State has all the powers not prohibited to it by the State or Federal Constitution. A State constitution is often, therefore, a summary of what the state legislative body may not do. The Virginia Constitution specifically states that "the authority of the General Assembly shall extend to all subjects of legislation, not herein forbidden or unrestricted; and a specific grant of authority in this Constitution upon a subject shall not work a restriction of its authority upon the same or any other subject." The principles described are further emphasized in this quotation from the Virginia Constitution which follows: "The omission in this Constitution of specific grants of authority heretofore conferred shall not be construed to deprive the General Assembly of such authority, or to indicate a change of policy in reference thereto, unless such purpose plainly appear." There are several limitations placed upon the General Assembly by the Constitution: the General Assembly cannot enact any local, special or private law in the following instances (but can enact general laws in the same instances): (1) for the punishment of crime, (2) for providing a change of venue (the place where a trial is held) in civil or criminal cases, (3) for regulating the jurisdiction of, or changing the rules of, evidence in any judicial proceeding, (4) for changing county seats, (5) for assessing and collecting taxes and for extending the time for assessment or collection of taxes, (6) for exempting property from taxation, (7) for postponing or diminishing any obligation or liability of any person, corporation or association to the State or to any local unit of government, (8) for refunding money lawfully paid into the treasury of the State or the treasury of any local unit of government, (9) for granting from the treasury of the State any extra compensation to any public officer, servant, agent or contractor, (10) for conducting elections or designating places of voting, (11) for regulating labor, trade, mining or manufacturing, or the rate of interest on money, (12) for granting any pension, (13) for creating, increasing or decreasing fees, salaries, percentages, or allowances of public officers during the term for which they are elected or appointed, (14) for declaring streams navigable or authorizing the constructions of booms or dams or the removal of obstructions from such streams, (15) for regulating fencing or the boundaries of land, or the running at large of stock,
