A pardon is a government decision to allow a person to be absolved of guilt for an alleged crime or other legal offense, as if the act never occurred. The pardon may be granted before or after conviction for the crime, depending on the laws of the jurisdiction.
Pardons can be granted in many countries when individuals are deemed to have demonstrated that they have "paid their debt to society", or are otherwise considered to be deserving of them. Pardons are sometimes offered to persons who were either wrongfully convicted or who claim that they were wrongfully convicted. In some jurisdictions of some nations, accepting a pardon may implicitly constitute an admission of guilt; the offer is refused in some cases. Cases of wrongful conviction are in recent times more often dealt with by appeal rather than by pardon; however, a pardon is sometimes offered when innocence is undisputed in order to avoid the costs that are associated with a retrial. Clemency plays a critical role when capital punishment is applied.
Pardons are sometimes seen as a mechanism for combating corruption, allowing a particular authority to circumvent a flawed judicial process to free someone that is seen as wrongly convicted. Pardons can also be a source of controversy. In extreme cases, some pardons may be seen as acts of corruption by officials in the form of granting effective immunity as political favors.
In Australia, the traditional pardon power is referred to as the royal prerogative of mercy, an executive power that is vested in the Queen and may be exercised by the Governor-General. The prerogative of mercy is a broad discretionary power that may be exercised by a state governor who is acting on the advice of the state executive council and the state attorney general. Courts in Australia may also exercise their traditional power to exercise mercy when the circumstances of the defendant or offense warrant relief.
In 2012, the Parliament of Canada passed the Safe Streets and Communities Act, which changed many of elements regarding the criminal justice system. The Act replaced the term "pardon" with "record suspension", and the pardon system was similarly changed.
The RCMP removes all information about the conviction for which an individual received the pardon from the Canadian Police Information Centre (CPIC). Federal agencies cannot give out information about the conviction without approval from the Minister of Public Safety Canada.
A pardon does not, however, erase the fact that an individual was convicted of a crime. The criminal record is not erased, but it is kept separate and apart from other (non-pardoned) criminal records.
If an individual in receipt of a pardon is convicted of a new offence, the information may lead to a reactivation of the criminal record for which the pardon was received in CPIC.
A pardon does not guarantee entry or visa privileges to another country. Before travelling to another country, individuals must still contact the authorities of the country in question to find out what the requirements are to enter that country.
Processing of pardons by the Parole Board of Canada generally takes six months for a summary offence and twelve months for an indictable offence. If the Parole Board proposes to deny the application, it can take 24 months to process.
Individuals can apply for a pardon if they were convicted as an adult of a criminal offense in Canada, or of an offense under a federal act or regulation of Canada, or if they were convicted of a crime in another country and were transferred to Canada under the Transfer of Offenders Act or International Transfer of Offenders Act. Non-Canadian citizens are not eligible for a Canadian pardon unless they were convicted of a crime in Canada.
To be eligible for a pardon or record suspension, individuals must have completed all of their sentences and a waiting period.
Individuals are considered to have completed all of their sentences if they have:
Before to 2012, following completion of all of their sentences, individuals must have completed a waiting period, as follows:
Effective 13 March 2012, the eligibility criteria and waiting periods changed:
Applicants for a record suspension must be able to show that they have completed their sentences in full and provide proof of payment.
Individuals can apply for a pardon by filling out the application forms available from the Parole Board and by paying a $631 pardon application fee.
In Canada, clemency is granted by the Governor-General of Canada or the Governor in Council (the federal cabinet) under the royal prerogative of mercy. Applications are also made to the National Parole Board, as in pardons, but clemency may involve the commutation of a sentence, or the remission of all or part of the sentence, a respite from the sentence (for a medical condition) or a relief from a prohibition (e.g., to allow someone to drive who has been prohibited from driving).
In Chile, the institution of pardon (indulto) is regulated in the Criminal Code (article 93, Nº 4º), which deals with the extinction of criminal liability. A pardon "only grants the remission or the commutation of the sentence; it does not remove the condition of having been condemned". The pardon may be either general, when it is granted to all those covered by a specific law passed by qualified quorum in National Congress, or particular, when it is granted by Supreme Decree of the President of the Republic. In Chile's presidential regime, the President is the Head of State; in this capacity, he or she has the discretionary power to grant particular pardons. He or she is not obliged to seek opinion or approval from other authorities, although, the granting of pardons is limited by the norms of Law No. 18.050 (1981), and its Regulations (Decree No. 1542 of 1981 on particular pardons), which forbid particular pardons for those convicted of a crime of terrorism.
On September 23, 2015, Al Jazeera journalists, Canadian Mohamed Fahmy and Egyptian Baher Mohamed, were among 100 activists released from prison after Egyptian president Abdel Fattah el-Sisi issued a pardon which he announced on his Facebook page. This marks the occasion of Eid al-Adha and the President's visit to the 70th session of the United Nations General Assembly which will take place later this week. The Al Jazeera Media Network has welcomed their release but continues to demand all charges and sentences against its journalists are dropped.
Pardons and acts of clemency (grâces) are granted by the President of France, who, ultimately, is the sole judge of the propriety of the measure. It is a prerogative of the President which is directly inherited from that of the Kings of France. The convicted person sends a request for pardon to the President of the Republic. The prosecutor of the court that pronounced the verdict reports on the case, and the case goes to the Ministry of Justice's directorate of criminal affairs and pardons for further consideration.
If granted, the decree of pardon is signed by the President, the Prime Minister, the Minister of Justice, and possibly other ministers involved in the consideration of the case. It is not published in the Journal Officiel.
The decree may spare the applicant from serving the balance of his or her sentence, or commute the sentence to a lesser one. It does not suppress the right for the victim of the crime to obtain compensation for the damages it suffered, and does not erase the condemnation from the criminal record.
When the death penalty was in force in France, all capital sentences resulted in a presidential review for a possible clemency. Executions were carried out if and only if the President rejected clemency, by signing a document on which it was written: "decides to let justice take its course".
The Parliament of France, on occasions, grants amnesty. This is a different concept and procedure from that described above, although the phrase "presidential amnesty" (amnistie présidentielle) is sometimes pejoratively applied to some acts of parliament traditionally voted upon after a presidential election, granting amnesty for minor crimes.
Similar to the United States, the right to grant pardon in Germany is divided between the federal and the state level. Federal jurisdiction in matters of criminal law is mostly restricted to appeals against decisions of state courts. Only "political" crimes like treason or terrorism are tried on behalf of the federal government by the highest state courts. Accordingly, the category of persons eligible for a federal pardon is rather narrow. The right to grant a federal pardon lies in the office of the President of Germany, but he or she can transfer this power to other persons, such as the chancellor or the minister of justice.
In early 2007, there was a widespread public discussion about the granting of pardons in Germany after convicted Red Army Faction terrorist Christian Klar, who was serving six consecutive sentences of life imprisonment, filed a petition for pardon. President Horst Köhler ultimately denied his request.
For all other (and therefore the vast majority of) convicts, pardons are in the jurisdiction of the states. In some states it is granted by the respective cabinet, but in most states the state constitution vests the authority in the state prime minister. As on the federal level, the authority may be transferred. Amnesty can be granted only by federal law.
The Constitution of Greece grants the power of pardon to the President of the Republic (Art. 47, § 1). He/She can pardon, commute or remit punishment imposed by any court, on the proposal of the Minister of Justice and after receiving the opinion (not the consent necessarily) of the Pardon Committee.
Prior to the transfer of the sovereignty in 1997, the power of pardon was the royal prerogative of mercy of the monarch of the United Kingdom. This was used and cited the most often in cases of convicts who had been given the death penalty: from 1965 to 1993 (when the death penalty was formally abolished) death sentences were automatically commuted to life imprisonment under the royal prerogative.
Since the transfer, the Chief Executive of Hong Kong now exercises the power to grant pardons and commute penalties under section 12 of article 48 Basic Law of Hong Kong. "The Chief Executive of the Hong Kong Special Administrative Region shall exercise the following powers and functions ... to pardon persons convicted of criminal offences or commute their penalties".
Under the Constitution of India (Article 72), the President of India can grant a pardon or reduce the sentence of a convicted person, particularly in cases involving capital punishment. A similar and parallel power vests in the governors of each state under Article 161.
The Constitution of India vests sovereign power in the president and governors. The governance in the centre and states is carried out in the name of the president and governor respectively. The president is empowered with the power to pardon under Article 72 of the Indian Constitution. Article 72 says that the president shall have the power to grant pardons, reprieves, respites or remissions of punishment or to suspend, remit or commute the sentence of any person convicted of any offence. The meaning of these terms is as follows:
The pardoning powers of the Indian President are elucidated in Art 72 of the Indian Constitution. There are five different types of pardoning which are mandated by law.
Article 72 reads:
(1) The President shall have the power to grant pardons, reprieves, respites or remission of punishment or to suspend remit or commute the sentence of any persons convicted of any offence-
(a) in all cases where the punishment or sentence is by a court martial;
(b) in all cases where the punishment or sentence is for an offence against any law relating to a matter to which the executive power of the Union extends;
(c) in all cases where the sentence is a sentence of death.
(2) Nothing in sub- clause (a) of clause (1) shall alter the power conferred by law on any officer of the Armed Forces of the Union to suspend, remit or commute a sentence passed by a Court Martial.
(3) Nothing in sub-clause (c) of clause (1) shall affect the power to suspend remit or commute a sentence of death exercisable by the Governor of a State under any law for the time being in force.
Similarly, as per article 161: Governor of a State has the power to grant pardons, reprieves, respites or remissions of punishment or to suspend, remit or commute the sentence of any person convicted of any offence against any law relating to a matter to which the executive power of the state extends. Please note that President can grant pardon to a person awarded death sentence. But a governor of a state does not enjoy this power.
The question is whether this power to grant pardon is absolute or this power of pardon shall be exercised by the President on the advice of Council of Ministers. The pardoning power of the president is not absolute. It is governed by the advice of the Council of Ministers. This has not been discussed by the constitution but is the practical truth. Further, the constitution does not provide for any mechanism to question the legality of decisions of President or governors exercising mercy jurisdiction. But the SC in Epuru Sudhakar case has given a small window for judicial review of the pardon powers of President and governors for the purpose of ruling out any arbitrariness. The court has earlier held that court has retained the power of judicial review even on a matter which has been vested by the Constitution solely in the Executive.
However, it is important to note that India has a unitary legal system and there is no separate body of state law. All crimes are crimes against the Union of India. Therefore, a convention has developed that the governor's powers are exercised for only minor offenses, while requests for pardons and reprieves for major offenses and offenses committed in the Union Territories are deferred to the President.
Both the President and Governor are bound by the advice of their respective Councils of Ministers and hence the exercise of this power is of an executive character. It is therefore subject to Judicial Review as held by the Supreme Court of India in the case of Maru Ram v. Union of India  INSC 213, 1981 (1) SCC 107, Supreme Court. It was subsequently confirmed by Kehar Singh v. Union of India  INSC 370, 1989(1) SCC 204, Supreme Court. In the case of Epuru Sudhakar & Anr vs Govt. Of A.P. & Ors  INSC 638, Supreme Court, it was held that "clemency is subject to judicial review and that it cannot be dispensed as a privilege or act of grace". The court made these observation while quashing the decision of then Governor of Andhra Pradesh Sushil Kumar Shinde in commuting the sentence of a convicted Congress activist.
The Irish constitution states (in Article 13.6) that
The right of pardon and the power to commute or remit punishment imposed by any court exercising criminal jurisdiction are hereby vested in the President, but such power of commutation or remission may also be conferred by law on other authorities.
The power of clemency is nominally exercised by the president. However, the President of Ireland must act "on the advice" of the Government (cabinet), so in practice the clemency decisions are made by the government of the day and the president has no discretion in the matter. The responsibility can also be delegated to people or bodies other than the president.
Amnesty and immunity, on the other hand, are usually dealt with by an Act of the Oireachtas rather than by a general form of pardon or a slate of individual pardons.
There are two methods by which a pardon may proceed:
In the first procedure, aimed at miscarriages of justice, the Minister for Justice may recommend to the Government that they formally advise the President to grant a pardon, and any conditions along with it. 1993 Criminal Procedure Act provides the method by which a person convicted of an offense may apply for a pardon. Under this procedure, the person must:
Then they can apply in writing to the Minister for Justice for a pardon. The minister may then "make or cause to be made such inquiries as they consider necessary" and may refuse to grant the pardon on his/her own initiative, or if they think the person should be pardoned, bring such argument to cabinet.
Section six of the act allows a Minister for Justice to seek or receive a pardon request from someone whose case is not a 'miscarriage of justice', but has some other fault, such as an archaic law, a law being misapplied by a rogue judge, a reduction in the harshness of a sentence or a substitution of a sentence, without having to go through the procedure above, gone through appeals, or presented new facts. It also allows the minister to waive the procedure in a case of miscarriage of justice if the specific case warrants it. It may also allow prospective pardons as it allows the minister to pardon someone who has not been convicted yet, which the other procedure requires.
The government itself may assemble a committee to study the case in more detail on their behalf. This may consist of anyone, and any number, but the chair must be:
This special committee may look to any material it sees fit to make its decision, even if it was not, or would not be, available to a jury or trial judge in a normal court. The government do not have to be bound by the committee recommendations.
Under Section 7(5) of the act, the same powers of the Minister for Justice apply to the Minister for Defense in the case of military officers and enlisted convicted by courts martial.
The Minister for Justice or Defense may also, in their absolute discretion, pay compensation, determined by them alone, to any person given a pardon, if this compensation is applied for. If they think the compensation is too low they may challenge for a higher figure in the High Court.
The power is used very infrequently compared to, for example, pardons in the United States.
In Italy, the President of the Republic may "grant pardons, or commute punishments" according to article 87 of the Italian Constitution. Like other acts of the president, the pardon requires the countersignature of the competent government minister. The Constitutional Court of Italy has ruled that the Minister of Justice is obliged to sign acts of pardon.
The pardon may remove the punishment altogether or change its form. Unless the decree of pardon states otherwise, the pardon does not remove any incidental effects of a criminal conviction, such as a mention in a certificate of conduct (174 c.p.) or the loss of civil rights.
According to article 79 of the Italian Constitution the Parliament may grant amnesty (article 151 c.p.) and pardon (article 174 c.p.) by law deliberated a majority of two-thirds of the components. The last general pardon, discounting 3 years from sentences, was approved in 2006.
In Poland, the President is granted the right of pardon by Article 139 of the Constitution of the Republic of Poland. As of October 2008, 7,819 people were pardoned, while 3,046 people's appeals were declined.
The President of the Russian Federation is granted the right of pardon by Article 89 of the Constitution of the Russian Federation. The chain of pardon committees manage lists of people eligible for pardon and directs them to the President for signing. While President Boris Yeltsin frequently used his power of pardon (1998 - 7,000 to 8,000 cases), his successor Vladimir Putin is much more hesitant; he granted five pardons in 2014 and two in 2015.
Pardon can be requested in any time. The next request can be submitted one year after the previous one.
The prerogative of mercy is a form of pardon that can be exercised by the President of Rwanda. The prerogative is one of the powers of the president defined by the Constitution of Rwanda, which came into effect in 2003 following a national referendum. According to the Constitution of Rwanda, "The President of the Republic has authority to exercise the prerogative of mercy in accordance with the procedure determined by law and after consulting the Supreme Court on the matter."
Under section 84(2)(j) of the Constitution of the Republic of South Africa, 1996 (Act 108 of 1996), the President of the Republic of South Africa is responsible for pardoning or reprieving offenders. This power of the President is only exercised in highly exceptional cases.
To pardon a person is to forgive a person for his/her deeds. The pardon process is therefore not available to persons who maintain their innocence and is not an advanced form of appeal procedure.
Pardon is only granted for minor offences after a period of ten years has elapsed since the relevant conviction.
For many serious offences (for example if the relevant court viewed the offence in such a serious light that direct imprisonment was imposed) pardon will not be granted even if more than ten years have elapsed since the conviction.
The derecho de gracia ("right of grace") or indulto ("pardon") is acknowledged by the Spanish Constitution of 1978 as a privilege of the King of Spain (article 62.i: "Functions of the King"). The Spanish Constitution defines it as a renounce on the State's part of its own punitive power on behalf of an individual, founded on reasons of equity or public interest. The Constitution subjects royal pardons to the Law and forbids general pardons, so they have to be granted individually. Theoretically, a royal pardon can be granted for a general offense or accessory offenses alone; if it is granted for a general offense, the accessory ones it implies are also pardoned, with the exception of punishments involving political rights (i.e., removal of the right to run for a public office as a result of a sentence), which have to be explicitly mentioned in the pardon decree if they are going to be pardoned.
The procedure and requirements for the grant of the pardon are given by the Law of 18 June 1870, modified by the Law 1/1988 of 14 January. The application for royal pardon has to be carried out by the convicted person himself, his relatives or any other person in his name. The convicting court will then issue a report of the case, which shall be considered along with the public comments of the Prosecutor and the victims of the crime if there were any. All of this is gathered by the Minister of Justice, who will present the pardon issue to the Cabinet of Ministers. If the Cabinet decides a pardon should be granted, then the Minister of Justice will recommend as such to the King. Pardons are issued by Royal Decree and have to be published in the Boletín Oficial del Estado ("Public Journal").
Pardons are not commonly conceded in Spain but for offenders convicted for minor crimes who are about to complete their sentence and have shown good behaviour and repentance. Dating back to medieval times, several organisations and religious brotherhoods still hold the right of granting pardons as part of some privilege or other granted to them by the King of Spain. The scope of this privilege depends on the royal charter received by the organisation when their right to concede pardons was granted, though it usually holds only for minor offenses in very especial conditions; this right is implicitly acknowledged by the public offices nowadays, though it is not exercised but following the usual procedure for royal pardons. Traditionally, they will propose some petty criminal about to end his sentence for pardon being granted to him, and he/she will be released following the tradition to which the pardon holds, usually during the Holy Week. This type of pardons are distinguished from the usual ones in that they only release the prisoner from jail, halting the sentence, but do not pardon the offense itself.
In Sri Lanka, under the Sri Lankan Constitution the President can grant a pardon, respite or substitute a less severe form of punishment for any punishment imposed to any offender convicted of any offence in any court within the Republic of Sri Lanka. It is generally referred to as a Presidential pardon.
In Switzerland, pardons may be granted by the Swiss Federal Assembly for crimes prosecuted by the federal authorities. For crimes under cantonal jurisdiction, cantonal law designates the authority competent to grant pardons (if any). In most cantons, the cantonal parliament may pardon felonies, and the cantonal government may pardon misdemeanors and minor infractions.
The president of Turkey is granted the right of pardon under certain circumstances defined in the constitution, article 104. According to the article, the president can "remit, on grounds of chronic illness, disability, or old age, all or part of the sentences imposed on certain individuals". After the convict's or his or her proxy's application, if the Council of Forensic Medicine determines that the convict suffers from chronic illness, disability, or old age, the Ministry of Justice presents the situation to the president, and the president can choose to grant a pardon.
Additionally, the parliament of Turkey has the power to announce general amnesty.
The power to grant pardons and reprieves in the United Kingdom is known as the royal prerogative of mercy. It was traditionally in the absolute power of the monarch to pardon an individual for a crime, whether or not he or she had been convicted, and thereby commute any penalty; the power was then delegated both to the judiciary and the sovereign's ministers. Since the creation of legal rights of appeal, the royal prerogative of mercy is no longer exercised by the person of the sovereign, or by the judiciary, but only by the government.
In constitutional terms, under the doctrine of the rule of law, the power of ministers to overrule the judiciary by commuting criminal sanctions imposed resolves different and sometimes conflicting public interests. In civil matters, only the legislative branch, and not ministers, have the power to override the judiciary.
Until the nineteenth century, for many crimes the sentence was mandatory and was formally pronounced in court immediately upon conviction, but judges and ministers were given powers to exercise the royal prerogative of mercy out of court, in order to mitigate the rigour of the law. Before there was any general form of criminal appeal, a judge might grant a pardon either by way of clemency, because he felt in his opinion that the law was unduly harsh (for example, in the case of convictions of minors), that the verdict was dubious, to seek public approval, or it was otherwise in the public interest. Capital sentences imposed by the assizes were generally executed when the assize was concluded and as the circuit judge left the town, so there was a limited window of time to apply to a judge or directly to the Crown for a pardon. Especially for assizes that were far away from the then capital and major cities of London, York, Durham, Edinburgh, or Dublin, a pardon might well arrive too late. Perhaps as a form of temporary punishment, to give solace, to avoid public disorder, to consult or obtain further evidence, or to maximise the public approval of the King's mercy, judges often did not grant their pardons until their departures; the convict often hoped until his last moments that the sentence of death would not actually be executed, and it was generally popular for a reprieve to arrive at the scaffold at the very moment of the execution.
The first known general pardon in post-Conquest England was issued during the celebrations at the coronation of King Edward III in 1327. In 2006, all soldiers from England, Wales, Scotland, and Ireland who were executed for cowardice during the First World War were given a statutory pardon by an Act of Parliament (the Armed Forces Act 2006), resolving a long-running controversy about the justice of their executions.
Today the sovereign only grants pardons upon the advice of her ministers: currently they are the Lord Chancellor, for England and Wales; the First Minister of Scotland; or the Secretary of State for Northern Ireland. The Secretary of State for Defence is responsible for military cases. It is the standard policy of the government to only grant pardons to those who are considered "morally" innocent of the offence, as opposed to those who may have been wrongly convicted by a misapplication of the law. Pardons are generally no longer issued prior to a conviction, but only after the conviction. The use of the royal prerogative of mercy is now a rare occurrence, given that the Criminal Cases Review Commission and the Scottish Criminal Cases Review Commission are now avenues to statutory remedies against miscarriages of justice.
Therefore, the grant of pardons is now very rare occurrence indeed, and the vast majority of acknowledged miscarriages of justice were decided upon by the courts. During the Birmingham Six case, Home Secretary Douglas Hurd stressed that he could only make the decision for a pardon if he was "convinced of [their] innocence", which at the time he was not.
One recent case was that of two drug smugglers, John Haase and Paul Bennett. They were pardoned in July 1996 from their sentences of imprisonment both of 18 years, having served some ten months, on the advice of Home Secretary Michael Howard. This was intended as a reward for their information given to the authorities, but there were speculations as to the motives of the Home Secretary. In 2008 they were sentenced to imprisonment for 20 and 22 years, respectively, after subsequent discovery that the information they gave was unreliable.
In 1980, after the courts had dismissed their appeals, the Home Secretary, William Whitelaw, used the royal prerogative of mercy to free David Cooper and Michael McMahon from their imprisonment, both having been convicted of murder on poor evidence.
Under the Act of Settlement 1701, a pardon cannot prevent a person from being impeached by Parliament, but a pardon may commute any penalties imposed for the conviction. In England and Wales no person may be pardoned for an offence under Section 11 of the Habeas Corpus Act 1679 (unlawfully transporting prisoners out of England and Wales).
In the United States, the pardon power for offenses against the United States is granted to the President of the United States under Article II, Section 2 of the United States Constitution which states that the President "shall have power to grant reprieves and pardons for offenses against the United States, except in cases of impeachment". The U.S. Supreme Court has interpreted this language to include the power to grant pardons, conditional pardons, commutations of sentence, conditional commutations of sentence, remissions of fines and forfeitures, respites, and amnesties.
The pardon power of the President applies only to convictions under federal law. Additionally, the power extends to military court-martial cases, as well as convictions in the Superior Court of the District of Columbia.
Almost all pardon petitions are addressed to the President, who grants or denies the request. In some cases, the President will, of his own accord, issue a pardon. Typically, applications for pardons are referred for review and non-binding recommendation by the Office of the Pardon Attorney, an official of the United States Department of Justice.
The governors of most of the 50 states have the power to grant pardons or reprieves for offenses under state criminal law. In other states, that power is committed to an appointed agency or board, or to a board and the governor in some hybrid arrangement (in some states the agency is merged with that of the parole board, as in the Oklahoma Pardon and Parole Board).
Nine states in the United States have boards of pardons and paroles that exclusively grant all state pardons. These states are: Alabama (Board of Pardons and Paroles), Connecticut (Board of Pardons and Paroles), Georgia (Board of Pardons and Paroles), Idaho (Commission of Pardons and Paroles), Minnesota (Board of Pardons), Nebraska (Board of Pardons), Nevada (Board of Pardon Commissioners), South Carolina (Board of Probation, Parole and Pardon), and Utah (Board of Pardons and Parole).
On at least three occasions, state governors--George Ryan of Illinois in 2003,Toney Anaya of New Mexico in 1986, and Martin O'Malley of Maryland in 2014--have commuted all death sentences in their respective states prior to leaving office.
Some criminals who testify for the prosecution put their life in jeopardy by doing so. To encourage witnesses to testify, the government may offer witness protection. In the United States Federal Witness Protection Program, about "95% of [witnesses in the program] are ... criminals." Those who testify for the prosecution may be offered immunity from prosecution for their own crimes.
