The Right to a Fair Trial in International Law (OUP 2021)When a person is facing execution, their right to a fair trial takes on urgent importance. International human rights bodies have recognised this reality in a number of ways. First, by acknowledging that the right to a fair trial interacts with other human rights. Second, by applying a heightened standard of “scrupulous respect” for fair trial rights in death penalty cases. Third, as a result of this heightened standard, international human rights bodies have modified the application of certain components of the right to a fair trial. Fourth, certain types of remedies have been ordered for fair trial violations in death penalty cases. In this post, we examine these four aspects of the right to fair trial in the context of the death penalty.

Interaction with other rights

When a person is charged with a crime that carries the death penalty, it is not only their fair trial rights that are in the frame. Most vividly, their right to life is under threat. In its General Comment No 36 on the Right to Life, the UN Human Rights Committee notes that “[v]iolation of the fair trial guarantees provided for in article 14 of the [International Covenant on Civil and Political Rights] in proceedings resulting in the imposition of the death penalty would render the sentence arbitrary in nature, and in violation of article 6 of the Covenant.”[1]

When a defendant suffers for years on death row, the right to a fair trial combines with the prohibition against torture or other cruel, inhuman or degrading treatment or punishment.[2] The imposition of the death penalty following an unfair trial by a court lacking independence and impartiality will amount to inhuman treatment.[3] In addition, the Human Rights Committee has emphasised that under no circumstances can the death penalty ever be applied as a sanction against conduct whose very criminalization violates the Covenant, including adultery, homosexuality, apostasy, establishing political opposition groups, or offending a head of state.[4]

If the defendant is a juvenile, the rights of the child also apply.[5] UN bodies have stated that individuals who were under the age of 18 at the time the crime was committed may not be sentenced to death, let alone be executed, regardless of their age at the time of trial or sentencing.[6]

Heightened standard of respect

The Human Rights Committee and the UN Economic and Social Council have stated that the respect for fair trial rights in death penalty cases is a heightened standard of “scrupulous respect.”[7] The Inter-American Court of Human Rights has held that “[b]ecause execution of the death penalty is irreversible, the strictest and most rigorous enforcement of judicial guarantees is required of the State so that those guarantees are not violated and a human life not arbitrarily taken as a result.”[8] The Inter-American Commission on Human Rights has developed a “heightened scrutiny” test in such cases.[9]

Modified application of component fair trial rights

The right to a fair trial is not a singular right. It has 13 component parts: right to a competent, independent and impartial tribunal established by law; public trial; presumption of innocence; right to prepare a defence; right to counsel; right to be tried without undue delay; right to be present; right to examine witnesses; right to an interpreter; right to silence; right to appeal; right to equality; and the right not to be subject to double jeopardy. Some of these component rights are modified to provide greater protection to a defendant facing the death penalty.

The right to prepare a defence includes the right to adequate time. The court may be required to order or extend an adjournment, even if it was not requested. For example, the Human Rights Committee reviewed a death penalty case in Guyana in which the defendant’s lawyer was absent on the first day of the trial and requested a two-day adjournment. The Human Rights Committee found a violation of the defendant’s right to have adequate time and facilities for the preparation of his defence considering that it “should have been manifest to the judge in a capital case that counsel’s request for an adjournment of the trial for only two week days, during which he was engaged in another case, was not compatible with the interests of justice, since it did not provide the author with adequate time and facilities to prepare his defence.”[10]

The right to “adequate facilities” is also necessary for preparing a defence. The Inter-American Court found a violation of the right to adequate facilities to prepare a defence when a defendant accused of murder in Barbados could not obtain an evaluation of his mental health during his trial. He was facing the possibility of a mandatory death sentence. The Court emphasised that the defendant’s case was different from “other criminal proceedings in which the State’s passive conduct with regard to the availability of mental health evaluations would be [permissible]” because, among other reasons, the potential death sentence meant that the proceedings required “the most ample and strict observation of due process rights.” The Court therefore concluded that there had been a violation of the defendant’s defence rights.[11]

The right to counsel and the right to appeal are probably the component rights most associated with death penalty proceedings. The Inter-American Court found a violation of the right to counsel when law students were permitted to represent defendants in a death penalty case, given the students’ lack of experience and training, and the impossibility of reversing a death sentence once it is carried out.[12]  The European Court of Human Rights considered a case in which a defendant who was the leader of the Kurdistan Workers' Party (PKK) group in Turkey was sentenced to death for crimes against the state. He was imprisoned on an island that had been declared a military zone and his counsel visits were limited by the frequency and departure times of the ferries to the island, resulting in two one-hour visits per week. The European Court found that this violated the right to a fair trial because “the presentation of [the] highly complex charges generated an exceptionally voluminous case file ... [and] the special circumstances of the case did not justify restricting the [defendant] to a rhythm of two one-hour meetings per week with his lawyers in order to prepare for a trial of that magnitude.”[13]

The Court noted that Turkey had not explained why it did not permit the lawyers to visit their client more often or why it failed to provide more adequate means of transport to the prison. Such measures were called for as part of the “diligence” which states must exercise to ensure that the right to a fair trial, including the right to counsel, is respected.[14]

Satisfying the right to appeal in death penalty cases requires effective representation by counsel. The Human Rights Committee has stated that a “denial of legal aid by the court reviewing the death sentence of an indigent convicted person constitutes not only a violation of article 14, paragraph 3(d) [(right to counsel)], but at the same time also of article 14, paragraph 5 [(right to appeal)], as in such cases the denial of legal aid for an appeal effectively precludes an effective review of the conviction and sentence by the higher instance court.”[15]

The right to appeal in these circumstances will also be violated “if defendants are not informed of the intention of their counsel not to put any arguments to the court, thereby depriving them of the opportunity to seek alternative representation, in order that their concerns may be ventilated at the appeal level.”[16] For example, in a case in which defence counsel “on appeal conceded that there was no merit in the appeal,” the Human Rights Committee found a violation of the right to counsel, holding that “the [domestic court] should ascertain whether counsel ha[d] consulted with the accused and informed him accordingly. If not, the [court] must ensure that the accused is so informed and given an opportunity to engage other counsel.”[17]

The UN Human Rights Council chamber, GenevaOver and above the strict counsel requirements, international human rights law prohibits the execution of any death penalty until the defendant has had “an opportunity to resort to all judicial appeal procedures” and “petitions to all other available non-judicial avenues have been resolved.”[18] The UN Death Penalty Safeguards provide that anyone who has been sentenced to death “shall have the right to appeal to a court of higher jurisdiction, and steps should be taken to ensure that such appeals shall become mandatory.”[19] The African Commission’s Fair Trial Principles contain an almost identical provision.[20] UN bodies and special rapporteurs have called on states that have the death penalty to “allow adequate time for the preparation of appeals to a court of higher jurisdiction and for the completion of appeal proceedings.”[21] The Inter-American Commission has emphasised that there is an “enhanced obligation to ensure that any deprivation of life which may occur through the application of the death penalty is in strict compliance with the right to a timely, effective and accessible appeal.”[22]

In addition to the right to appeal, a defendant sentenced to death has the right “to seek pardon or commutation.”[23] The Human Rights Committee has recommended that “such procedures should be specified in domestic legislation, and they should not afford the families of crime victims a preponderant role in determining whether the death sentence should be carried out.”[24]

The right to be tried without undue delay also applies stringently to defendants facing the death penalty. The Human Rights Committee has stated that “in all cases, and in particular in capital cases, the accused is entitled to trial and appeal proceedings without undue delay.”[25] In one case, a 22-month delay between the defendant’s arrest and trial constituted a violation of the right to be tried without undue delay.[26] Further, if a defendant is on death row after conviction, there may be a violation of the right to be tried without undue delay if the period between sentencing and exhaustion of the final appeal takes too long. The Human Rights Committee found a violation when there was a delay of 51 months between a defendant’s conviction and the dismissal of his appeal. According to the Committee, “a delay of four years and three months in hearing an appeal in a capital case is, barring exceptional circumstances, unreasonably long and incompatible with article 14, paragraph 3 (c), of the Covenant.”[27]

The right to examine witnesses must also be strictly observed. The Human Rights Committee found that, at least in death penalty cases, the right is violated if counsel is absent during the questioning of a witness and the court fails to adjourn the proceedings to give the defendant an opportunity to ensure the presence of his counsel.”[28]

The right to equality before the courts also takes on special urgency in death penalty cases involving people with disabilities. The Inter-American Commission has held that states have “the obligation to have procedures in place to identify those accused or convicted persons who have a mental or intellectual disability” and once there is an indication that a person might have such a disability, the State is obliged “at any time of the proceedings, to address the claim on the merits.”[29]

Remedies for fair trial violations in death penalty cases

Certain remedies may be more appropriate when persons facing the death penalty have suffered fair trial violations. The Economic Community of West Africa States (ECOWAS) Community Court of Justice, for example, has emphasised the importance of release as a remedy in a case involving two people convicted by a military court and held on death row for over 22 years who had their rights to an impartial court and appeal violated.[30]

A fresh trial may also be called for. The Inter-American Court of Human Rights ordered a retrial in a case in which the charge was reclassified from an offence of “aggravated rape” to “murder”, a charge that could lead to the death penalty. The defendant’s right to a prepare a defence had been violated.[31]

International bodies have also often recommended commutation of a death sentence to a prison term in cases in which a death sentence has been imposed following an unfair trial.[32] Commutation, however, does not necessarily fully remedy violations of the right to a fair trial and it may be necessary to order states both to commute or stay the death sentence and to release the defendants,[33] or to consider a further sentence reduction or early release.[34]

Finally, certain international bodies have issued remedies directed at preventing future violations in death penalty cases. For example, the Inter-American Court ordered Barbados to bring its constitution into compliance with the American Convention because a “savings clause” in the constitution prevented domestic courts from declaring a mandatory death sentence to be invalid.[35] The Inter-American Commission has also recommended that the United States “[p]rovide every indigent person accused of a capital offense with the necessary legal representation and “[e]nsure that legal counsel provided ... in death penalty cases is effective, trained to serve in death penalty cases, and able to thoroughly and diligently investigate all mitigating evidence.”[36]
