Guide for Expressing and Reporting Opinions for Handwriting Examination
Terminology:
Recommended Terminology – Document Examiners are encouraged to use the following terms when writing an opinion.
Identification (the strongest opinion of identity) – In this case, based on the evidence at hand, identification is made within a reasonable degree of professional certainty. Other than natural variation, which is expected, no unexplainable characteristics are observed. The known writing compares favorably to the questioned writing. The writing contains substantial similarities, no significant dissimilarities, and there are no limitations associated with quantity or quality of writing or documentation.
Strong Probability Did Write – There are substantial significant similarities in the range of writing and no significant dissimilarities. However, there may be limitations imposed, such as insufficient comparison characters and/or insufficient quantity of exemplars.
Probably Did Write – There are few significant similarities in the range of writing and no significant dissimilarities. There are limitations associated with the examination that preclude a stronger opinion. These limitations may include a lack of appropriate comparison material.
Inconclusive – The range of writing may contain similarities and/or dissimilarities, but they are insufficient to make a determination of authenticity. Additionally, limitations may be placed on the examination due to quality and/or quantity of comparison materials, or other constraints.
Probably Did Not Write – There are significant dissimilarities in the range of writing and no significant similarities. However, there may be limitations imposed, such as insufficient comparison characters and/or insufficient quantity of writing exemplars.
Strong Probability Did Not Write – There are substantial significant dissimilarities in the range of writing and no significant similarities. However, there may be limitations imposed, such as insufficient comparison characters and/or insufficient quantity of writing exemplars.
Eliminations (the strongest opinion of rejection) – Based on the evidence at hand, the examiner is absolutely certain that the writer of the known writing is not the writer of the questioned writing. The writing contains substantial dissimilarities, no significant similarities, and there are no limitations associated with quantity or quality of writing.
In Daubert, the U.S. Supreme Court made it clear that, “it would be unreasonable to conclude that the subject of scientific testimony must be known to a certainty; arguably there are no certainties in science. Science represents a process for proposing and refining theoretical explanations about the world that are subject to further testing and refinement. It is sufficient if the testimony can be supported by appropriate validation, I. EE., Good grounds based on what is known.”
