Inslaw

Inslaw is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Inslaw rather than just read about it. In short: Inslaw, Inc. is a Washington, D.C.–based information technology company that markets case management software for corporate and government users. Inslaw is known for developing PROMIS, an early case management software system.

Key takeaways

  • Inslaw belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Inslaw to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Inslaw from memory before moving on to harder problems.

Reference excerpt

Inslaw, Inc. is a Washington, D.C.–based information technology company that markets case management software for corporate and government users. Inslaw is known for developing PROMIS, an early case management software system. It is also known for a lawsuit that it brought against the United States Department of Justice (DOJ) in 1986 over PROMIS, alleging that the Justice Department had dishonestly conspired to "drive Inslaw out of business 'through trickery, fraud and deceit'" by withholding payments to Inslaw and then pirating the software. Inslaw won damages in bankruptcy court, but these were overturned on appeal. The suit resulted in several Justice Department internal reviews, two Congressional investigations, the appointment of a special counsel by Attorney General William P. Barr, and a lengthy review of the special counsel's report under Attorney General Janet Reno. Inslaw's claims were finally referred by Congress to the Court of Federal Claims in 1995, and the dispute ended with the Court's ruling against Inslaw in 1998. During the 12-year long legal proceedings, Inslaw accused the Department of Justice of conspiring to steal its software, attempting to drive it into Chapter 7 liquidation, using the stolen software for covert intelligence operations against foreign governments, and involvement in a murder. These accusations were eventually rejected by the special counsel and the Court of Federal Claims.

History of Inslaw 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.

Development of PROMIS

PROMIS (Prosecutors Management Information System) was a case management software developed by Inslaw. The software program was developed with aid from the Law Enforcement Assistance Administration to aid prosecutors' offices in tracking cases. PROMIS software was originally written in COBOL for use on mainframe computers; later a version was developed to run on 16 bit mini-computers such as the Digital Equipment Corporation PDP-11. The primary users of this early version of the software were the United States Attorneys Office of the District of Columbia, and state and local law enforcement. Both the mainframe and 16 bit mini-computer versions of PROMIS were developed under LEAA contracts, and in later litigation, both Inslaw and DOJ eventually agreed that the early version of PROMIS was in the public domain, meaning that neither the Institute nor its successor had exclusive rights to it.

The Promis implementation contract In 1979, the DOJ contracted with the Institute to do a pilot project that installed versions of PROMIS in four US Attorneys offices; two using the mini-computer version, and the other two a "word-processor" version which the Institute was developing. Encouraged by the results, the Department decided in 1981 to go ahead with a full implementation of locally based PROMIS systems, and issued a request for proposals (RFP) to install the mini-computer version of PROMIS in the 20 largest United States Attorneys offices. This contract, usually called the "implementation contract" in later litigation, also included developing and installing "word-processor" versions of PROMIS at 74 smaller offices. The now for-profit Inslaw responded to the RFP, and in March 1982 was awarded the three-year $10 million contract by the contracting division, the Executive Office of United States Attorneys (EOUSA). Having previously developed a 16-bit version of PROMIS, Inslaw developed a 32-bit version, for various operating systems, specifically VAX/VMS, Unix, OS/400, and (in the 1990s) Windows NT.

Contract disputes and Inslaw bankruptcy The contract did not go smoothly. Disputes between EOUSA and Inslaw began soon after its execution. A key dispute over proprietary rights had to be solved by a bi-lateral change to the original contract. (This change, "Modification 12," is discussed below.) EOUSA also determined that Inslaw was in violation of the terms of an "advance payment" clause in the contract. This clause was important to Inslaw's financing and became the subject of months of negotiations. There were also disputes over service fees. During the first year of the contract, the DOJ did not have the hardware to run PROMIS in any of the offices covered by the contract. As a stopgap measure, Inslaw provided PROMIS on a time-share basis through a VAX computer in Virginia, allowing the offices to access PROMIS on the Inslaw VAX through remote terminals, until the needed equipment was installed on-site. EOUSA claimed that Inslaw had overcharged for this service and withheld payments. The DOJ ultimately acquired Prime computers, and Inslaw began installing PROMIS on these in the second year of the contract, in August 1983. The "word-processor" PROMIS installation, however, continued to have problems, and in February 1984 the DOJ cancelled this portion of the contract. Following this cancellation, the financial condition of Inslaw worsened, and the company filed for Chapter 11 bankruptcy in February 1985.

Worked examples

Example 1 — a first encounter with Inslaw

Start with the simplest possible case. Write down what Inslaw claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Inslaw before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Inslaw ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Inslaw

In research
Inslaw appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Inslaw in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Inslaw is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies that filed for Chapter 11 bankruptcy in 1985, Companies that have filed for Chapter 11 bankruptcy, Companies that have filed for Chapter 7 bankruptcy, so understanding it makes those chapters shorter.
In everyday life
Look for Inslaw outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
