Probation in criminal law is a period of supervision over an offender, ordered by a court instead of serving time in prison.
In some jurisdictions, the term probation only applies to community sentences (alternatives to incarceration), such as suspended sentences. In others, probation also includes supervision of those conditionally released from prison on parole.
An offender on probation is ordered to follow certain conditions set forth by the court, often under the supervision of a probation officer. During the period of probation an offender faces the threat of being incarcerated if found breaking the rules set by the court or probation officer.
Offenders are ordinarily required to refrain from possession of firearms, and may be ordered to remain employed or participate in an educational program, abide to a curfew, live at a directed place, obey the orders of the probation officer, or not . The probationer might be ordered as well to refrain from contact with the victims (such as a former partner in a domestic violence case), with potential victims of similar crimes (such as minors, if the instant offense involves child sexual abuse), or with known criminals, particularly co-defendants. Additionally, the restrictions can include a ban on possession or use of alcoholic beverages, even if alcohol was not involved in the original criminal charges. Offenders on probation might be fitted with an electronic tag (or monitor), which signals their whereabouts to officials. Also, offenders have been ordered to submit to repeat alcohol/drug testing or to participate in alcohol/drug or psychological treatment, or to perform community service work.
The concept of probation, from the Latin, probatio, "testing," has historical roots in the practice of judicial reprieve. In English common law, prior to the advent of democratic rule, the courts could temporarily suspend the execution of a sentence to allow a criminal defendant to appeal to the monarch for a pardon. Probation first developed in the United States when John Augustus, a Boston cobbler, persuaded a judge in the Boston Police Court in 1841 to give him custody of a convicted offender, a "drunkard," for a brief period and then helped the man to appear rehabilitated by the time of sentencing. Even earlier, the practice of suspending a sentence was used as early as 1830 in Boston, Massachusetts, and became widespread in U.S. courts, although there was no statutory provision for such a practice. At first, judges, most notably Peter Oxenbridge Thatcher of Boston, used "release on recognizance" or bail and simply refrained from taking any further action. In 1878 the mayor of Boston had hired a former police officer, the ironically named "Captain Savage," to become what many recognize as the first official probation officer. By the mid-19th century, however, many Federal Courts were using a judicial reprieve to suspend sentence, and this posed a legal question. In 1916, the United States Supreme Court, in the Killets Decision, held that a Federal Judge (Killets) was without power to suspend a sentence indefinitely. This decision led to the passing of the National Probation Act of 1925, thereby, allowing courts to suspend the imposition of incarceration and place an offender on probation. Probation developed from the efforts of a philanthropist, John Augustus, who looked for ways to rehabilitate the behavior of criminals.
