Corrections

Why does a society need a separate system for what happens after sentencing?

Because a sentence is a decision that still has to be carried out, by someone other than the court that made it, over a period of time. Two statutes state the purpose of that work expressly — and they state it differently.

In short

A correctional system is the part of a justice system that operates after the court has finished. It carries out sentences — custodial and non-custodial — supervises people serving them, and prepares for and manages the point at which a sentence ends. It is a separate function because carrying out a decision is a different task from making one, and a society that authorises imprisonment has to do both.

Why it exists

AnalysisThe plainest reason is temporal. A judgment is delivered in an afternoon; a sentence of years is served across them. Something has to exist in the interval, and whatever exists there will be making decisions — about where a person is held, what they can do, who they see, when they are considered for release. Those decisions are consequential enough that leaving them unstructured is not an option.

AnalysisThe second reason is separation. The body that carries out a sentence should not be the body that imposed it, for the same reason the body that investigates should not be the body that tries. A court that both sentenced and administered would be reviewing its own work daily, and a person serving the sentence would have no one to appeal to who was not already committed to the decision.

How it works

Some legislatures answer the question directly, in the text of the law. Germany’s Prison Act does so in a single provision headed Aufgaben des Vollzuges — the tasks of execution. Section 2 states that in the execution of a custodial sentence the prisoner soll … fähig werden, künftig in sozialer Verantwortung ein Leben ohne Straftaten zu führen — shall become capable of leading a life in social responsibility without offences in future. The statute names this the Vollzugsziel, the goal of execution. It then adds that execution dient auch dem Schutz der Allgemeinheit vor weiteren Straftaten — also serves the protection of the general public from further offences.

Brazil answers in the opening article of its execution statute, and answers differently. Article 1 of the Lei de Execução Penal states that penal execution tem por objetivo efetivar as disposições de sentença ou decisão criminal e proporcionar condições para a harmônica integração social do condenado — has as its objective to give effect to the provisions of the sentence or criminal decision, and to provide conditions for the harmonious social integration of the convicted person.

AnalysisThe two provisions share one idea and differ on the other. Both name the person’s future life outside as something execution is for. Germany then names public protection; Brazil instead names giving effect to what the court decided. Those are not the same second purpose, and a system built on each would answer differently when the two pull apart.

AnalysisWhere a statute says nothing, the purpose has to be inferred from what the system does — which is a weaker basis for any claim about it. Silence in legislation is common and is not evidence that a system has no purpose; it is evidence that the purpose was not fixed by the legislature.

Alongside national purposes sit international minimum standards. The United Nations Standard Minimum Rules for the Treatment of Prisoners set out what is expected of the function regardless of who operates it, including the requirement that prisons be inspected by a body independent of the prison administration. These are agreed standards rather than the law of any particular state, and they bind only through whatever domestic law adopts them.

Common misconceptions

Widely held beliefs that do not match how the system actually operates.

Common belief: Prisons exist to punish, and everything else is decoration.
In practice: Some legislatures say otherwise in their own text. Germany’s Prison Act names the capacity to live without offences as the goal of execution and public protection as something it also serves; punishment is not the word the provision uses. Whether that describes practice is a separate question the statute does not answer.
Common belief: Every system agrees that rehabilitation is the point.
In practice: They do not, and the ones that name it do not mean the same thing by it. Brazil pairs social integration with giving effect to the court’s decision; Germany pairs it with protecting the public. The second half of each pairing is where the systems diverge.
Common belief: Corrections is simply the last stage of the court process.
In practice: It is a separate function with its own decisions, its own decision-makers and, in some systems, its own courts. Treating it as an appendix to the trial hides where most of the decisions affecting a sentenced person are actually made.
Common belief: International standards decide what prisons are for.
In practice: They set minimum conditions and require independent inspection. They do not settle the purpose of imprisonment, which every legislature answers for itself or leaves unanswered.

How this varies between jurisdictions

A required section on every guide. Arrangements differ between countries, and we say how.

The most useful comparative question is not what a system says its purpose is, but where it says it.

In a dedicated execution statute, as a named goal — Germany, StVollzG § 2.
In the opening article of an execution statute, paired with giving effect to the sentence — Brazil, LEP Art. 1.
Nowhere in legislation, so that the purpose is whatever practice and case law make it.

Rights and accountability

AnalysisA stated purpose is useful to a reader precisely because it can be held up against practice. A system that names reintegration as its goal has given anyone inspecting it a standard drawn from its own law, which is harder to dismiss than a standard imported from elsewhere.

The structural point that follows is the one the international standards make: closed institutions are the part of a justice system where the people affected are least able to be seen or heard, which is why external inspection here is a standing function rather than a response to complaints.

What we could not establish

This page describes the purposes two legislatures state for the execution of custodial sentences. It does not assess whether either system achieves them, which would require outcome evidence the platform does not hold.
Two statutes were read from primary text. Nothing here describes the purposes any other country states, and several countries state none in legislation at all.

Where to go next

What is a sentence supposed to achieve?
Four legislatures answer in their own words, and they do not agree — not on the purposes, and not even on whether the question belongs in sentencing law at all. Where a system puts its answer turns out to be as informative as the answer.
Is being sentenced one decision, or several?
Three, and in some systems three different decision-makers. Brazil gives execution its own judge — the Juízo da Execução — which makes visible a stage most descriptions of criminal justice leave out entirely.
What is a prison system supposed to have achieved by the time someone leaves?
Two legislatures answer in their own text, and neither answer is “that the person has been reformed”. One names a capacity; the other names conditions the state must provide. The difference is where the obligation sits.

Where this connects

Institutions: Correctional service.

The authoritative German text of § 2 of the Prison Act, headed "Aufgaben des Vollzuges" — the tasks of execution — read directly. Supports verbatim: "Im Vollzug der Freiheitsstrafe soll der Gefangene fähig werden, künftig in sozialer Verantwortung ein Leben ohne Straftaten zu führen (Vollzugsziel). Der Vollzug der Freiheitsstrafe dient auch dem Schutz der Allgemeinheit vor weiteren Straftaten." In the execution of a custodial sentence the prisoner shall become capable of leading a life in social responsibility without offences — this is named as THE Vollzugsziel, the goal of execution — and execution ALSO serves the protection of the general public from further offences. Cited for the fact that a statute can state the purposes of imprisonment expressly, and for the specific two-purpose structure Germany states. It supports no claim about whether the goal is achieved, no claim about any other country, and no normative theory of punishment. Note also that since the 2006 federalism reform prison law is substantially a Land competence and the Länder have enacted their own execution statutes; this federal provision is cited for what it states, not as a description of every German prison regime.

The authoritative Portuguese text, read in full. Supports the corrections framework: penal execution 'tem por objetivo efetivar as disposições de sentença ou decisão criminal e proporcionar condições para a harmônica integração social do condenado' (Art. 1); the órgãos da execução penal include the Juízo da Execução, the Ministério Público, the Conselho Penitenciário and the Departamentos Penitenciários (Art. 61); the Departamento Penitenciário Nacional is 'subordinado ao Ministério da Justiça' as the federal executive body (Art. 71); and the 'Departamento Penitenciário local, ou órgão similar, tem por finalidade supervisionar e coordenar os estabelecimentos penais da Unidade da Federação a que pertencer' (Art. 74) — i.e. each state runs its own prisons.

Supports the internationally agreed minimum standards for the treatment of people in detention, including the requirement of independent inspection of prisons. Standards, not a description of conditions in any particular prison system. WAVE 17 ADDITION, read from the primary UNODC PDF, text-extracted locally. Supports Rule 83(1): "There shall be a twofold system for regular inspections of prisons and penal services: (a) Internal or administrative inspections conducted by the central prison administration; (b) External inspections conducted by a body independent of the prison administration, which may include competent international or regional bodies"; and Rule 83(2): that in both cases the objective is to ensure prisons are managed in accordance with existing laws, regulations, policies and procedures, with a view to bringing about the objectives of penal and corrections services, and that the rights of prisoners are protected. Supports Rule 84(1): inspectors shall have authority to access all information on the numbers of prisoners and places and locations of detention and all information relevant to the treatment of prisoners including their records and conditions of detention; "to freely choose which prisons to visit, including by making unannounced visits at their own initiative, and which prisoners to interview"; to conduct private and fully confidential interviews with prisoners and prison staff; and to make recommendations to the prison administration and other competent authorities. Supports Rule 84(2): external inspection teams shall be composed of qualified and experienced inspectors appointed by a competent authority and shall encompass health-care professionals, with due regard to balanced gender representation. Supports Rule 85(1): every inspection shall be followed by a written report to the competent authority, with due consideration given to making external inspection reports publicly available excluding personal data unless the prisoner has given explicit consent; and Rule 85(2): the administration or other competent authorities shall indicate within a reasonable time whether they will implement the recommendations. Supports Rule 54: on admission every prisoner shall be promptly provided with written information about the prison law and regulations, their rights including authorized methods of seeking information and access to legal advice and procedures for making requests or complaints, their obligations including applicable disciplinary sanctions, and all other matters necessary to adapt to prison life; and Rule 55: that this information shall be available in the most commonly used languages, with interpretation assistance where the prisoner understands none of them, conveyed orally to an illiterate prisoner, and provided appropriately to prisoners with sensory disabilities. Supports Rule 56: every prisoner shall have the opportunity each day to make requests or complaints to the prison director or an authorized staff member; that it shall be possible to make them to the inspector of prisons during inspections, with the opportunity to talk to the inspector "freely and in full confidentiality, without the director or other members of the staff being present"; that every prisoner shall be allowed to make a request or complaint regarding their treatment "without censorship as to substance" to the central prison administration and to the judicial or other competent authorities including those vested with reviewing or remedial power; and that these rights extend to the prisoner's legal adviser and, failing that, to a family member or other person with knowledge of the case. Supports Rule 57: every request or complaint shall be promptly dealt with and replied to without delay, and if rejected or unduly delayed the complainant shall be entitled to bring it before a judicial or other authority; that safeguards shall ensure requests can be made safely and confidentially where requested, and that a complainant "must not be exposed to any risk of retaliation, intimidation or other negative consequences"; and that allegations of torture or other cruel, inhuman or degrading treatment shall be dealt with immediately and result in a prompt and impartial investigation by an independent national authority. Supports Rule 87: that before the completion of the sentence it is desirable that the necessary steps be taken to ensure for the prisoner a gradual return to life in society.
