law procedure. Upon returning, he also established his own law firm, in which he was joined by his brothers Stephen and Jonathan. Much of Field's ideas on codification and the civil procedure rules were based on the 1825 Louisiana Code of Procedure. The Louisiana code was drafted by jurists including Edward Livingston, Louis Lislet (1762–1832), and Pierre Derbigny. In turn, the Louisiana code was inspired by French (including the French Code of Civil Procedure of 1806), Spanish, and Roman law, the common law tradition, and Livingston's Louisiana Practice Act of 1805. European civil law thus influenced American civil procedure, partially through the intermediary of Louisiana. Livingston helped to prepare criminal and civil codes for Louisiana, and Field's personal papers at Duke University Libraries reveal that he had read Livingston's 1825 report on the Louisiana Civil Code. Field was also influenced by criticism of the common law by his law partner Henry Sedgwick, as well as lawyer William Sampson. Field devoted more than 40 years to this codification project. He began by outlining his proposed reforms in pamphlets, professional journal articles, and legislative testimony, but met with a discouraging lack of interest. In 1846, Field's ideas gained wider notice with publication of a pamphlet, "The Reorganization of the Judiciary", which influenced that year's New York State Constitutional Convention to report in favor of a codification of the laws. In 1847 he finally had a chance to put his ideas into official form when he was appointed head of a state commission to revise court procedure and practice. The first part of the commission's work, a portion of the code of civil procedure, was reported and enacted by the legislature in 1848. By January 1, 1850, the New York state legislature had enacted the complete Code of Civil Procedure, subsequently known as the Field Code since it was almost entirely Field's work. The new system abolished the distinction in forms of procedure between an action at law (a civil case demanding monetary damages) and a suit in equity (a civil case demanding non-monetary damages). Under the new procedure, rather than having to file separate actions, a plaintiff needed to file only one civil action (or as it is often called today, a lawsuit). Eventually Field's civil procedure code was, with some changes, adopted in 24 states. It also influenced later procedural reforms in England and several of her colonies (specifically, the Judicature
