Recently, the Subcommittee on the Prevention of Torture has stated that it “considers
that an evidence-led and not confession-led approach to criminal investigation to be
one of the fundamental safeguards, as it would render having recourse to extracting
confessions by means of ill-treatment meaningless and thus reduce considerably the
risk of ill-treatment of persons in police custody.”129
82.
In the case of Mexico, the subscription of judges at all levels to the doctrine of
“procedural immediacy”, as interpreted in the current case - that spontaneous
confessions under pressure are more reliable than exculpatory statements made after
pause for reflection - may drive confessions in police custody to be given more weight
in criminal proceedings.
83.
The doctrine of procedural immediacy relies in part for its legitimacy on a notion that
subsequent “ratifications” of incriminating statements void any concerns about the way
in which they were initially obtained, because the defendant has a chance to speak in
front of the judge with all the protections that entails. However, it is unrealistic to expect
that someone who has been tortured to confess to a crime will not also be threatened
with further mistreatment should he/she speak about the torture before the prosecutor
and/or judge.130 Therefore, the presumption of voluntariness applied to such statements
is misplaced.
84.
More specifically, there is substantial evidence that the protections in Mexico’s national
legislation and Constitution have been undermined by the Supreme Court’s insistence
that, when there are two conflicting statements from a suspect, the earlier in time is to
be preferred.131 Unsurprisingly, this earlier statement is usually made in police custody,
at the early stages of detention. It is well known that the first moments after
apprehension or arrest are those where the risk of torture or other forms of ill-treatment
is greatest.132 In addition, the Supreme Court has narrowly interpreted the requirement
that the statement be “established” or “verified” to have been made as a result of
torture, placing a burden on the defendant which is very difficult to meet, and has
allowed confessions alone to form bases for conviction.133
85.
In this connection, the Inter-American Commission of Human Rights in Manríquez v
Mexico has stated: “the principal of procedural immediacy as conceived by the Mexican
State, instead of serving as a procedural guarantee for persons accused of crimes, is
134
becoming its antithesis, a source of abuses of the accused.”
86.
In cases involving ‘confirmation’ of confessions, such as the present case, national
courts generally reject the Mexican approach. In an Article gathering relevant
jurisprudence for a recent Congress of the International Academy of Comparative Law,
Professor Stephen Thaman of St Louis University wrote:
“Regarding fruits of involuntary confessions, the US [Supreme Court] has
intimated in Oregon v Elstad, that a confession which otherwise comports with
