Truth in Criminal Law
and Procedure:
The Erosion of a Fundamental Value
1. Introductory remarks
Writing or talking about ‘truth’ is walking through a mine eld. For thousands of years, philosophers have
debated the question of what truth is, as well as the related question of whether man can know the truth
or can otherwise approach it, or whether he simply creates truth in his mind. It would be presumptuous of
me to try to add anything of substance to this debate. I therefore take a very naive layman’s perspective and
make a few basic everyday assumptions:
Reality exists. But we cannot be certain that we can recognise it, because man can conceive of the
world around him only within the capacity and limits of his mind. It is only within these limits that
a person can make sense of reality and can make statements about it, but, on the other hand, this
limited view of reality is su cient for inter-human communication.
People sometimes make statements that, with great probability, do not re ect reality and that we
can therefore call ‘false’. Such statements may be consciously false (we then call them lies) or may
be made in good faith – that is, the person wrongly believes that his or her words do re ect reality.
The truth of a statement can thus be distinguished from the honesty of the person who makes it.*1
In what follows, I will address the relevance of truth (and its protection) in criminal procedure and
criminal law. Although these two areas are obviously interconnected in many ways, the signi cance of truth
di ers greatly between them. The justi cation (or, perhaps, excuse) for treating them jointly lies in the fact
that the importance of truth seems to be receding in both areas, and there may be good reason for discuss-
ing whether the relevance of protecting the truth and searching for it was overrated in the past, and what
changes may be necessary.
Although this distinction is clear in theory, one may ask whether criminal law should prohibit the spreading of ‘objective’
falsehood, or whether only those who act dishonestly should be subject to criminal punishment; for discussion of the concept
of ‘false testimony’ in German law, see H.E. Müller, in: K. Miebach (ed.), Münchener Kommentar zum Strafgesetzbuch,
