Destructive Methods

Questioned document examination occupies an important position in forensic science. Its purpose is to provide the authority conducting legal proceedings with reliable knowledge conﬁrming or excluding authenticity of a document, therefore every eﬀort should be made to use relevant and legally admissible examination methods. For many years reliable non-destructive methods have been developed, whose use in expert examination will enable subsequent control both by the authority conducting legal proceedings and other parties in the proceedings. This article proposes the use of alternative non-destructive methods in examination of documents.

Effective Use

Due to a document’s important role in social interaction it is frequently forged or counterfeited, which has its impact on penal, civil and administrative legal proceedings. In the interest of evidential proceedings it is paramount that a document suffers minimum damage during an examination. Moreover, due to the need to implement various examination methods and the limitations of their effectiveness, the results of document examination sometimes fall short of expectations, which is reflected in the ambiguity of final conclusions. This article discusses effective use of non-invasive methods in forensic examination of documents. The presented case involved several non-invasive methods, including colorimetry. Confronting a few methods implemented in a particular case of document examination increases the accuracy and objectivity of its results and improves chances for formulating correct final conclusions

Sufficient experience has been gained during the past five years to suggest an extended application of microreplication and scanning electron microscopy to problems of forensic science. The author's research was originally initiated with a view to develop a non-destructive method for identification of materials that went into objects of art, notably ivory and ivories. This was followed by a very specific application to the identification and duplication of the kinds of materials from animal teeth and tusks which two centuries ago went into the fabrication of the ivory dentures of George Washington. Subsequently it became apparent that a similar method of microreplication and SEM examination offered promise for a whole series of problems pertinent to art, technology and science. Furthermore, what began primarily as an application to solid substances has turned out to be similarly applicable to soft tissue surfaces such as mucous membranes and skin, even in cases of acute, chronic and precancerous epithelial surface changes, and to post-mortem identification of specific structures pertinent to forensic science.
