Mandatory sentencing
Mandatory sentencing requires that people convicted of certain crimes serve a predefined term of imprisonment, removing the discretion of judges to take issues such as extenuating circumstances and a person's likelihood of rehabilitation into consideration when sentencing. Research shows the discretion of sentencing is effectively shifted to prosecutors, as they decide what charges to bring against a defendant. Mandatory sentencing laws vary across nations; they are more prevalent in common law jurisdictions because civil law jurisdictions usually prescribe minimum and maximum sentences for every type of crime in explicit laws. They can be applied to crimes ranging from minor offences to extremely violent crimes including murder.
Mandatory sentences are considered a "tough on crime" approach that intend to serve as a general deterrence for potential criminals and repeat offenders, who are expected to avoid crime because they can be certain of their sentence if they are caught. However, studies have shown that the effects of mandatory sentencing are mixed, and that in some cases crime increases following their implementation. Mandatory sentencing is not cost-effective compared to other methods of reducing crime, and has been found to disproportionately impact Indigenous peoples and other minorities in several countries. In the United States, several mandatory sentencing laws have been overturned by the Supreme Court for being unconstitutional, and mandatory sentencing has resulted in prison terms that are considered extremely disproportionate compared to the crimes committed.
History
North America
Throughout US history, prison sentences were primarily founded upon discretionary sentencing. Mandatory sentencing and increased punishment were enacted when the United States Congress passed the Boggs Act of 1951. The act made a first time cannabis possession offense a minimum of two to ten years with a fine up to $20,000; however, in 1970, the United States Congress repealed mandatory penalties for cannabis offenses. With the passage of the Anti-Drug Abuse Act of 1986 Congress enacted mandatory minimum sentences for drugs, including marijuana, with 2-3 years for a first offence and 5-10 years for a second. The Anti-Drug Abuse Act of 1986 also implemented mandatory sentencing for offences related to cocaine. In 1994, Safety Valve laws were created to reduce mandatory sentencing for certain nonviolent, non-managerial drug offenders with little or no criminal history.Individual states in the US can have mandatory sentences. In 1994, California introduced a three-strikes law, which imposed a mandatory term of life-imprisonment for a third felony conviction; the law was intended to reduce crime by deter repeated offenders. However, the laws have created cases where sentences are considered extremely disproportionate to the crimes committed. For example, Santos Reyes was sentenced to life imprisonment with a non-parole period of 29 years after he was convicted of perjury in relation to cheating on his drivers licence test in 1997. Reyes had previous convictions for burglary and armed robbery more than 11 years earlier, making the perjury charge his third strike. Other examples include Curtis Roberts, who was sentenced to life imprisonment with a non-parole period of 50 years for three non-violent thefts which combined only obtained $116.
Following their implementation in California, three-strike laws were subsequently adopted in many American jurisdictions. The state of Florida has a very strict minimum sentencing policy known as 10-20-Life, which includes the following minimums: 10 years' imprisonment for using a gun during a crime, 20 years' imprisonment for firing a gun during a crime, and 25 years' imprisonment in addition to any other sentence for shooting somebody, regardless of whether they survive or not.
Separate from each state's own courts, federal courts in the United States are guided by the Federal Sentencing Guidelines. When a guideline sentencing range is less than the statutory mandatory minimum, the latter prevails. Under the Controlled Substances Act, prosecutors have great power to influence a defendant's sentence and thereby create incentives for defendants to accept a plea agreement. For example, defendants with prior drug felonies are often subject to harsh mandatory minimums, but a prosecutor can exercise discretion to not file a prior felony information. Then the mandatory minimum will not be applied. United States federal juries are generally not allowed to be informed of the mandatory minimum penalties that may apply if the accused is convicted because the jury's role is limited to a determination of guilt or innocence. However, defense attorneys sometimes have found ways to impart this information to juries; for instance, it is occasionally possible, on cross-examination of an informant who faced similar charges, to ask how much time he was facing. It is sometimes deemed permissible because it is a means of impeaching the witness. However, in at least one state court case in Idaho, it was deemed impermissible.
In 2013, United States Attorney General Eric H. Holder, Jr. announced that the Justice Department would follow a new policy restricting mandatory minimum sentences in certain drug cases. Prosecutions dropped, drug enforcement agent morale dropped, and fentanyl and heroin overdoses soared, reported The Washington Post in 2019. In Alleyne v. United States the Supreme Court held that increasing a sentence past the mandatory minimum requirement must be submitted by a jury and found factual beyond a reasonable doubt. It increases the burden on the prosecutor to show that the sentence is necessary for the individual crime by requiring that a mandatory minimum sentence be denied for a defendant unless they fulfill certain criteria. Attorney General Holder held that the charges placed on an individual should reflect the uniqueness of the case and consideration in assessing and fairly representing his/her given conduct. This purpose is to prevent recidivism.
Some mandatory sentence laws have been found to be unconstitutional by the Supreme Court of the United States. In 1976, mandatory death sentences were determined to be unconstitutional, following the decision in Woodson v. North Carolina. In 2005, United States v. Booker found that mandatory federal sentencing guidelines violated the Sixth Amendment right to a trial by jury. This resulted in the guidelines becoming advisory rather than mandatory. In 2010, the case of Graham v. Florida ruled it is unconstitutional to sentence people under 18 to mandatory life-imprisonment without parole for non-homicide offenses.
Mandatory sentencing in the US is more likely to affect minority groups. In US federal prisons, Black Americans sentenced under mandatory minimum drug laws grew from under 10% in 1984 to 28% by 1990, representing a significantly larger shift than found in the federal prison population in general. As of 2011, of the people convicted of an offense carrying a mandatory minimum punishment and who remained subject to that penalty at sentencing, 38.5 percent were Black, 31.8 percent were Hispanic, and 27.5 percent were White.
In Canada, life imprisonment and a period of parole ineligibility are mandatory for murder. The minimum parole ineligibility periods for first-degree murder are 25 years for an adult or youth tried and sentenced as an adult, and 10 years for a youth. Until 1961, murder in Canada was punishable only by death, provided that the offender was a sane adult. Until September 1, 1999, the National Defence Act specified a mandatory death sentence for certain acts if done traitorously.
Europe
Denmark has mandatory minimum sentences for murder and regicide, deadly arson is punished with imprisonment from 4 years to life, and for an illegal loaded gun one year in state prison.In Germany, murder for pleasure, sexual gratification, greed or other base motives, by stealth or cruelly or by means that pose a danger to the public or to facilitate or cover up another offense is mandatorily punished by life imprisonment.
In Ireland, Acts of the Oireachtas specify a mandatory sentence of life imprisonment for murder and treason, and mandatory minimum sentences for various lesser offences. A mandatory minimum sentence may be truly mandatory or may be presumptive, giving a judge discretion to impose a lesser sentence in exceptional circumstances. Mandatory sentences have been challenged on grounds that they violate the separation of powers required by the constitution, by allowing the Oireachtas to interfere in the judicial process. In 2012, the Supreme Court ruled that the mandatory sentence of life imprisonment for murder was constitutional. However, in 2019, it ruled that a mandatory minimum sentence had to apply for all offenders, not for certain classes of offenders. It struck out a sentence of five years for possession of a firearm, because it was truly mandatory only for a second offence, whereas it would have been presumptively mandatory for a first offence. A mandatory sentence for a second offence of drug trafficking was struck out in 2021 for similar reasons; the conviction was upheld but the sentence referred back to the Circuit Court for reconsideration.
In the United Kingdom, upon conviction for murder, the court must sentence the defendant to life imprisonment. The law requires that courts must set a minimum term before they become eligible for parole. For this purpose five "starting points" are in place that give guidance to a judge to impose a sentence in each different case of murder. These range from 12 years' imprisonment for cases of murder committed by a person under 18, to a whole life order, in cases that involve such "exceptionally" high aggravating factors, such as the murder of two or more persons, or the murder of a child following abduction or with sexual/sadistic motivation. The United Kingdom also has three other mandatory minimum sentences for certain offences, namely: a minimum of 7 years' imprisonment for a person over 18 convicted of trafficking, supplying or producing Class A drugs for the third or subsequent time; a minimum of 5 years' imprisonment or 3 years' imprisonment for possession, purchase, acquisition, manufacture, transfer or sale of a prohibited firearm or weapon for the first or subsequent time; and a minimum of 3 years' imprisonment for a person over 18 convicted of a domestic burglary for the third or subsequent time.
A "three strikes" policy was introduced to the United Kingdom by the Conservative government in 1997. This legislation enacted a mandatory life sentence on a conviction for a second "serious" violent or sexual offence, a minimum sentence of seven years for those convicted for a third time of a drug trafficking offence involving a class A drug, and a mandatory minimum sentence of three years for those convicted for the third time of burglary. An amendment by the Labour opposition established that mandatory sentences should not be imposed if the judge considered it unjust. According to figures released by the British government in 2005, just three drug dealers and eight burglars received mandatory sentences in the next seven years, because judges thought a longer sentence was unjust in all other drug and burglary cases where the defendant was found guilty. However, in 2005 a new "two strikes" law became effective, requiring courts to presume that a criminal who commits his second violent or dangerous offence deserves a life sentence unless the judge is satisfied that the defendant is not a danger to the public. This resulted in far more life sentences than the 1997 legislation. In response to prison overcrowding, the law was changed in 2008 to reduce the number of such sentences being passed, by restoring judicial discretion and abolishing the presumption that a repeat offender is dangerous.
