OVERVIEW OF THE MAIN IMPLEMENTATION CHALLENGES AND RELATING
INTERNATIONAL STANDARDS
Scope of application of the exclusionary rule
Time and again it was reported that there is still confusion as to the scope of application of the
exclusionary rule.
The prohibition of the use of confessions and statements obtained through cruel, inhuman and
degrading treatment
Many countries prohibit in absolute terms the use of confessions and statements obtained through
torture. An absolute prohibition means that the exclusionary rule operates without discretion for the
judiciary, in other words there can be no balancing act. However, doubts continue to arise on whether
the use of confessions and statements obtained as a result of cruel, inhuman or degrading treatment
is subjected to the same standards.
Although not always consistent, international standards on the matter do show that the prohibition
should be applied also to the use of confessions and statements obtained through cruel, inhuman and
degrading treatment. While Article 15 CAT only refers to torture, in its 2008 General Comment on
Article 2, the CAT Committee considered that ”articles 3 to 15 are likewise obligatory as applied to
both torture and ill-treatment”.3 Similarly, in the reporting procedure, the CAT Committee has
criticised a country’s legal framework for not explicitly providing for an exclusionary rule also for cruel,
inhuman and degrading treatment.4 However, the CAT Committee takes a more cautious approach in
its jurisprudence, where it concluded that Article 15 does not apply to cruel, inhuman or degrading
treatment in the case Kirsanov v Russia (see also below the contribution of Juan E. Méndez* “Torturetainted evidence and the exclusionary rule”). 5
The European Court of Human Rights (ECtHR) has further clarified that statements and confessions
obtained as a result of torture as well as other forms of ill-treatment under Article 3 ECHR are always
inadmissible, irrespective of their probative value and of whether their use was decisive in securing
the defendant’s conviction (see also below the contribution of Nikolaos Sitaropoulos “Unfair trial due
to torture-tainted evidence - European Court of Human Rights’ judgments and their execution”). 6 In
Gäfgen v Germany,7 the ECtHR stated that:
“… In respect of confessions … the admission of statements obtained as a result of torture … or of other
ill-treatment in breach of Article 3 … as evidence to establish the relevant facts in criminal proceedings
rendered the proceedings as a whole unfair. This finding applied irrespective of the probative value of
the statements and irrespective of whether their use was decisive in securing the defendant’s
conviction”
