The story

Inslaw began as a non-profit organization called the Institute for Law and Social Research. The Institute was founded in 1973 by William A. Hamilton to develop case management software for law enforcement office automation. Funded by grants and contracts from the Law Enforcement Assistance Administration (LEAA), the Institute developed a program it called "PROMIS", an acronym for Prosecutors' Management Information System, for use in law enforcement record keeping and case-monitoring activities. When Congress voted to abolish the LEAA in 1980, Hamilton decided to continue operating as a for-profit corporation and market the software to current and new users. In January 1981 Hamilton established the for-profit Inslaw, transferring the Institute's assets over to the new corporation.
