The Role of the Modern Document Examiner
by Timothy T. W. Allen
This article is intended as a general introduction to the
roll of the Document Examiner and to briefly indicate
the expert evidence available to be put before the Courts
in respect of documents the authenticity of which is
queried. The question has often been asked how 'strong'
is the evidence. The best reply is that it is an Expert
Opinion, based on the interpretation of photographic
evidence as presented, and resulting from years of
expert examination of innumerable documents of all
kinds.
Since time immemorial documents in one form or
another have formed an important part of our daily
lives, from the clay tablets and papyrus of ancient times,
the parchments of the Middle Ages, to the paper of the
present day.
The amount of written material in use today, cheques,
financial contracts, sales agreements, wills and the like,
lead the unscrupulous to commit forgery or at the very
least mis-represent material facts.
Forgery and the abuse of documents are the fields of
expert investigation by the duly qualified Documents
Examiner, previously known in vague and sometimes
derisory terms, as the Handwriting Expert. The Docu-
ment Examiner is not to be confused with the Graphol-
ogist, the latter being defined by PA Osborne, Journal
of Forensic Science 1983, as an Expert who determines a
person's character from handwriting, as opposed to the
Document Examiner who examines writing to determine
whether or not it is genuine. Writing in this context
includes signatures.
Duly qualified Documents Examiners have received
highly specialised training from UK Home Office
Experts and for many years practised their expert skills
either as Document Examiners in one of the UK Home
Office Laboratories or whilst as serving Police Officers
in one of the smaller UK or Service Forces. Many such
qualified Document Examiners, particularly those in the
smaller Forces, are experts in Police photography, in
particular where it relates to the special photographic
techniques required in document photography and print
enlargement necessary for the production of specialised
photographic supplements in document examination
cases.
The Document Examiner looks beyond the overall
appearance of a particular writing (including printing)
and examines for characteristic configuration in indiv-
idual letter formation and other distinctive points
particular to handwriting and/or signatures on a
document. On ascertaining the particular characteristic
points a comparison is then made between the exhibit
(suspect) material and the authenticated (control)
material. The Document Examiner will form his
opinion as to whether or not a particular writing is
genuine on the basis of the number of similar or dis-
similar characteristic points. As well as the stated opinion
of the Document Examiner, evidence before the Courts
will include a photographic supplement of enlarged
prints marked to indicate the characteristic points in
question, in effect visibly demonstrating in factual form
the basis for the opinion.
With typewriting, in addition to paper samples, lay-
out, etc., the Document Examiner examines for minute
cast variations and/or wear and tear characteristics in
the subject printing as produced by the type head. It is
incorrect to assume, for instance, that all modern "golf
ball" type heads of a given face must produce identical
typed material. Under low power (30x) microscopic
examination characteristics can be detected that are
individual to a particular typing head. Enlarged photo-
graphic prints are again used to demonstrate such
evidence before the Courts.
In addition to the individual letter typing variations
there is also the all important typing alignment and
spacing, particularly relevant when it is suspected that
typed additions have been made to an original
document. The re-insertion of an original document
into a machine for additional typing results in the
failure to obtain exact alignment and correct spacing,
clearly visible when the material under examination has
been subjected to expert photographic techniques and
enlarged prints prepared.
Sceptics may refer to classic examples of where the so-
called 'handwriting expert' has been proved wrong in
his opinion. With, however, modern expert training and
the considerable advance in photographic techniques
the present day Document Examiner appears before the
Courts as a fully competent witness demonstrating
support for his opinion by means of his expertly
produced photographic and other aids.
As in many cases involving the use of expert witnesses,
two conflicting opinions may well be submitted for con-
sideration by the Courts. As already explained the
Document Examiner will have prepared his photo-
graphic evidence indicating characteristic points of
similarity and/or dissimilarity. In the normal course of
events the expert witness who produces the most reason-
able basis for his opinion will have such opinion receive
favourable consideration. •
News about the
International Law Association
A number of international lawyers in Ireland are about to
establish an Irish Branch of the International Law Association.
The inaugural meeting will be on Friday, 18 April, and the guest
of honour is Judge Nagendra Singh, the President of the Inter-
national Court of Justice.
The focal point of the International Law Association's
activities is the series of Biennial Conferences held in different
countries. The Conferences provide a forum for discussion
between academics, practitioners and government lawyers from
over 40 countries and have often resulted in the adoption of
resolutions that have had a significant influence on the develop-
ment of international law. The Irish Branch of the Association
anticipates having a Spring and Autumn meeting each year.
