The prohibition on torture gives rise to the obligation erga omnes – an obligation toward the
international community as a whole owing to the fundamental and universal nature of the
norm – to take steps to eradicate torture worldwide.19 This includes the obligation of all
States to prevent and suppress torture and other forms of ill-treatment in territories under
their jurisdiction, but also to refrain from encouraging, assisting or recognizing such abuses.
Torture material as evidence
International law prohibits in absolute terms the use of evidence obtained through torture in
any proceedings. This exclusionary rule, contained in Article 15 of the Convention against
Torture, applies to “any proceedings” and has been interpreted to include civil, criminal and
administrative court proceedings as well as a broad range of decision-making processes by
state officials.20
The UN Committee Against Torture, tasked with monitoring compliance with the Convention
against Torture, has interpreted the exclusionary rule as applicable to extradition
proceedings.21
The principle rationale behind the exclusionary rule is to remove any incentive to engage in
torture by making it impossible to use statements extracted through such abuse.22 It is
therefore linked inextricably to the goal of preventing torture.
In practice, however, it can be difficult to exclude evidence, at any stage of the process, on
the grounds that it was obtained through torture. In some jurisdictions, the burden is
explicitly on the defendant (or applicant in civil cases) to show that the material was
obtained under torture. In others, the standard of proof is set so high that in practice the
evidence can only be excluded if the affected person is able to provide the court with
information demonstrating that it was so obtained. When the torture took place in a third
country, this can be an arduous task even if a defendant or applicant suffered the torture
