What is the purpose of consolidating and codifying legislation
Further, portions of some Congressional acts, such as the provisions for the effective dates of amendments to codified laws, are themselves not codified at all.
These statutes may be found by referring to the acts as published in "slip law" and "session law" form.
An example is the Council Directive of 15 July 1975 on waste, which has been amended several times and was consolidated on 20 November 2003, this consolidation then being used as a basis for the codified instrument.In the United States, acts of Congress, such as federal statutes, are published chronologically in the order in which they become law – often by being signed by the President, on an individual basis in official pamphlets called "slip laws", and are grouped together in official bound book form, also chronologically, as "session laws".The "session law" publication for Federal statutes is called the United States Statutes at Large.In law, codification is the process of collecting and restating the law of a jurisdiction in certain areas, usually by subject, forming a legal code, i.e. Codification is the defining feature of civil law jurisdictions.Ancient Sumer's Code of Ur-Nammu was compiled circa 1230-2050 BC, and is the earliest known surviving civil code.
A very influential example in Europe was the French Napoleonic code of 1804.
