Point in time legislative systems

Point in time legislative systems allow the user to retrieve legislation as it existed (or will exist) at some time in the past or future. They are often built out from legislative drafting and promulgation systems that conceive legislative document management as a continuous process that extends from drafting by legislative staff to publishing. Creation of such systems thus typically involves a certain amount of process reengineering directed at the management of legislative documents. Such systems can recover their costs by reducing the transfer costs inherent in the movement of documents through the process of multiple drafts, consideration, amendment, and passage; proofreading and reprinting at each of these many stages can be quite costly.

The first such system was EnAct, written by Timothy Arnold-Moore for the government of Tasmania.
