The judgment of a court is the legal conclusion from certain facts. Unless it is a legal conclusion from the facts on which it purports to rest it is erroneous, and, if there is any higher court of appeal, can be reversed. If such a judgment depends upon a statute which justifies or forbids the act or omission which constituted the cause of action, it is legal or illegal according as this statute is or is not law. It cannot be law if its provisions contravene rules laid down by the Constitution of the State to restrict the legislative power. The court which tries the cause must meet this question whenever it arises like any other and decide it. A court of law must be governed by law. What has the form of law is not law, in a country governed by a written constitution, unless it is consistent with all which that instrument provides. The first decision of an American court bottomed on these principles was probably rendered as early as 1780, and in New Jersey.[Footnote: Holmes _v._ Walton, IV _American Historical Review_, 456.] One of her greatest statesmen, who after taking a distinguished part in framing the federal Constitution became a justice of the Supreme Court of the United States, vigorously enforced the same doctrine on the circuit fifteen years later in trying a cause turning on the unconstitutionally of a confirming act passed by the legislature of Pennsylvania. "I take it," Justice Patterson said in charging the jury, "to be a clear position that if a legislative act oppugns a constitutional principle the former must give way and be rejected on the score of repugnance. I hold it to be a position equally clear and sound that in such case it will be the duty of the court to adhere to the Constitution, and to declare the act null and void."[Footnote: Vanhorne's Lessee _v._ Dorrance, 2 Dallas' Reports, 304, 309, 316.]
