Controlling Inadvertent Ambiguity In The Logical Structure Of Legal Drafting By Means Of The Prescribed Definitions Of The A-Hohfeld Structural Language, Layman E. Allen, Charles S. Saxon Jan 1994

Controlling Inadvertent Ambiguity In The Logical Structure Of Legal Drafting By Means Of The Prescribed Definitions Of The A-Hohfeld Structural Language, Layman E. Allen, Charles S. Saxon

Articles

Two principal sources of imprecision in legal drafting (vagueness and ambiguity) are identified and illustrated. Virtually all of the ambiguity imprecision encountered in legal discourse is ambiguity in the language used to express logical structure, and virtually all of· the imprecision resulting is inadvertent. On the other hand, the imprecision encountered in legal writing that results from vagueness is frequently, if not most often, included there deliberately; the drafter has considered it and decided that the vague language· best accomplishes the purpose at hand. This paper focuses on the use of some defined terminology for minimizing inadvertent ambiguity in the …


Automatic Generation Of A Legal Expert System, Layman E. Allen, Charles S. Saxon Jan 1991

Automatic Generation Of A Legal Expert System, Layman E. Allen, Charles S. Saxon

Book Chapters

The use of the AUTOPROLOG system to generate automatically a legal expert system is described in this chapter. The interpretation of a statutory or other legal rule by one expert (or by the consensus of a group of experts) expressed in a normalized form is the only input needed by the AUTOPROLOG system (which includes Turbo Prolog, the AUTOPRO program, and some data files) to produce automatically a computer program that is an expert system for that legal rule. The process for producing a legal expert system for Section 213.1 of the Modal Penal Code, which deals with rape and …


Untangling "Operation Common Sense": Reopening And Review Of Social Security Administration Disability Claims, Elizabeth S. Ferguson Jun 1989

Untangling "Operation Common Sense": Reopening And Review Of Social Security Administration Disability Claims, Elizabeth S. Ferguson

Michigan Law Review

Part I of the Note outlines how the SSA processes a disability claim and illustrates the ambiguity in the language of the reopening regulations that has caused the split in the courts. Part II examines the four interpretations of the reopening regulations created by courts. Part II begins with the Secretary's interpretation and concludes that this interpretation is plainly inconsistent with the language of the regulations. Thus, courts need not defer, as they normally would, to an agency's interpretation of its own regulation. This Part next examines the alternative interpretations of these regulations advanced by various courts, and describes how …


Exploring Computer Aided Generation Of Questions For Normalizing Legal Rules, Layman E. Allen, Charles S. Saxon Jan 1988

Exploring Computer Aided Generation Of Questions For Normalizing Legal Rules, Layman E. Allen, Charles S. Saxon

Book Chapters

The process of normalizing a legal rule requires a drafter to indicate where the intent is to be precise and where it is to be imprecise in expressing both the between-sentence and within-sentence logical structure of that rule. Three different versions of a legal rule are constructed in the process of normalizing it: (1) the logical structure of the present version, (2) the detailed marker version, and (3) the logical structure of the normalized version. In order to construct the third version the analyst must formulate and answer specific questions about the terms that are used to express the logical …


Language, Law, And Logic: Plain Legal Drafting For The Electronic Age, Layman E. Allen Jan 1980

Language, Law, And Logic: Plain Legal Drafting For The Electronic Age, Layman E. Allen

Book Chapters

The achievement of current demands for clearer legal drafting in the United States (New York, 1973 and President's Executive Order, 1978) and Great Britain (Renton Report, 1975) can be aided by applying modern logic to improve the language of the law. In considering how the expression of legal norms can be clarified by using some formal language techniques, particular attention will be given to alternatives for dealing with problems of inadvertent imprecision in current legal drafting, alternatives that facilitate human understanding as well as enhance the possibilities for analysis by computer. A brief sketch of the imprecision of the expression …


The Problem Of Communications In Meeting The Information Requirements Of The Courts, Layman Allen Jan 1966

The Problem Of Communications In Meeting The Information Requirements Of The Courts, Layman Allen

Book Chapters

My remarks are addressed to one aspect of the general problem of communication involved in meeting the information requirements of the courts. It transcends merely the court; however, it is a problem throughout the legal decision-making system. The efficiency of t:ourts in processing information is just one part of a larger picture of effective communication within the legal system. Phrased broadly, the question involves discerning the optimum man-machine mix in the processing of information. Nobody can reasonably quarrel with the goal of taking the fullest possible advantage of the benefits of emerging technology, as long as objectives of greater importance …


Symbolic Logic: A Razor-Edged Tool For Drafting And Interpreting Legal Documents, Layman E. Allen Jan 1957

Symbolic Logic: A Razor-Edged Tool For Drafting And Interpreting Legal Documents, Layman E. Allen

Articles

A large amount of the litigation based on written instruments-whether statute, contract, will, conveyance or regulation-can be traced to the draftsman's failure to convey his meaning clearly. Frequently, of course, certain items may purposely be left ambiguous, but often the question in issue is due to an inadvertent ambiguity that could have been avoided had the draftsman clearly expressed what he intended to say. In this Article it is suggested that a new approach to drafting, using certain elementary notions of symbolic logic, can go a long way towards eliminating such inadvertent ambiguity. This new approach makes available to draftsmen …
