Questioned writing examined, may be compared and concluded as being written by the same writer as the specimen of known writings, if both the absence of fundamental differences and the compelling presence of numerous significant similarities of both common and unusual features, is found to exclude the reasonable likelihood of the similarities being due to coincidence (known as a chance match).
The examiner considering the document evidence, may conclude that a questioned writing is inconsistent with being by the writer of an adequate specimen of known writings, if this is indicated by the presence of compelling fundamental structural differences between the writings, (provided that the differences could not reasonably be attributed to accidental occurrence or disguise).
The document examination comparison process includes assessment of the writer’s personal ‘range of variation’ for the formation of each letter, and each numeral.
Limiting factors in the examination and comparison process, such as insufficient samples to allow assessment of the writer’s ‘range of variation’, could contribute to either a limited conclusion or an inconclusive conclusion.
Submitting Questioned Handwriting Evidence
Questions concerning Handwriting evidence should be directed to 0480 245 392
- Handwriting evidence should be preserved in the condition in which it was found. It should not be highlighted in colour, folded, ironed-out flat, torn, marked, soiled, stamped, written on, or handled unnecessarily. Protect the evidence from inadvertent indented writing. Try to avoid marking the document. Mark only a copy of it, or label it if necessary for identification purposes.
- Whenever possible, the client should endeavour to submit the originals of the handwriting evidence to the document examiner. A typical lack of fine detail in photocopies may make examinations more difficult.
