121. International criminal jurisprudence contains cases of the equality of arms
in some major decisions. In the case of The Prosecutor v. Clément Kayishema and
Obed Ruzindana, the International Criminal Tribunal for Rwanda held that
“the right of an accused to a fair trial implies the principle of equality of arms
between the Prosecution and the defence”. The Tribunal went on to recall the
provisions of its Statute under which equality of arms includes, among
others, “the right to have adequate time and facilities to prepare his or her
defence”. 29 Moreover, in order to determine the scope of equality of arms, the
Tribunal drew from the decision handed down in the case of The Prosecutor v.
Tadić in which the International Criminal Tribunal for the Former Yugoslavia
held that “equality of arms obligates a judicial body to ensure that neither
party is put at a disadvantage when presenting its case”.30
122. The European Court of Human Rights case law follows the same path in
the case of Neumeister v. Austria, where it refers to the equality of arms as part
of a fair trial before an independent and impartial tribunal.31 Reiterating this
principle the other way round, the European Court held in a subsequent
decision, Delcourt v. Belgium, that “a trial would not be fair if it took place in
such conditions as to put the accused unfairly at a disadvantage.”32
123. As for the scope of application of the equality of arms, the European Court
takes the position that equality of arms applies to all proceedings involving
rights or civil obligations, even if the content of the principle does not have
the same implication in criminal and civil matters. 33 Although the European
Court thus gives this principle a general scope, it did not intend to make it
absolute. States are not required to establish strict procedural equality
between the parties, but rather to ensure that the parties benefit from a
reasonably egalitarian situation. It is also in the administration of evidence
that the European Court assesses whether or not there is equality of arms, in
terms of both the possibility of witnesses being heard34 or on the judge's
power to order or refuse an investigative measure. 35
124. The Human Rights Committee of the United Nations, for its part, takes
equality of arms beyond the confines established by the European Court in
the case of Robinson v. Jamaica to find out, beyond legal weapons, if indeed the
