The conditions of release are classified as a licence and parole is released on licence. There are seven standard licensing conditions for all prisoners:  “He violated his probation contract and was not released until 2014.” Most agree that the probation system, as originally planned, focuses on rehabilitation, despite its current problems, which are the subject of wide discussion. Critics note that it is becoming more and more costly for the taxpayer, with no evidence of a successful rehabilitation of prisoners. Probation conditions themselves are often attacked, criticized for its rapid and continuous mass surveillance and a permanent state of incarceration that does little to ensure a smooth reintroduction into society.  Critics point out that greater discretion is needed to decide which probation sentences would reimburse costly prudential resources and those that are not, rather than imposing numerical, physical and structural restrictions on any probation officer.  Despite its resemblance to the word “watchword,” the parol rule of evidence has nothing to do with criminal law. The Parol rule of evidence is a contractual doctrine that prevents parties to a written contract from providing “extrinsic” evidence of contract terms that contradict, alter or alter the terms of a written agreement if that written agreement is considered complete and concluded.  The second case in which parol evidence is admitted is proof of a security agreement. Penologist Zebulon Brockway introduced a suspended sentence when he became superintendent of Elmira Reformatory in Elmira, New York. To manage the prison population and rehabilitate inmates, it has implemented a two-part strategy of indefinite sentences and probation conditions.  This was important in prison reform, as prisoners began their rehabilitation during incarceration, as evidenced by a probation committee.  It also emphasized the protection of prisoners from cruel and unusual punishment. According to a review of academic literature by economist Jennifer Doleac, reducing probation supervision was one of the most cost-effective ways to improve the reintegration and rehabilitation of former inmates.
  Before being granted parole privilege, the inmate meets with members of the probation committee and is interviewed, the probation officer also has a psychological examination. The inmate must first agree to comply with the probation conditions set by the paraolar authority. In prison, the inmate signs a probation certificate or contract. On this contract, there are the conditions that the detainee must comply with. These conditions generally require the probation officer to meet regularly with his probation officer or community agent, who assesses the probation officer`s behaviour and accommodation and determines whether the probation officer is in breach of any of his or her conditions of detention (as a general rule, being at home for certain hours described as a curfew, maintaining a stable job , not escape, by renouncing illegal drug use and sometimes non-alcohol use), participation in drug or alcohol counselling and lack of contact with their victim. The inmate indicates an address that will be validated by probation officers before the inmate is released on parole. The courts are not allowed to enter into a contract for the parties. If the parties do not have an explicit or tacit agreement on the essential terms of the contract, there is no contract. Courts have the power only to apply contracts for the parties, not to write them down.
To be enforceable, a contract must be valid. The Tribunal`s role is to enforce agreements only if they exist and not to create them by imposing conditions that the court deems appropriate. Since the 1990s, parole and indeterminate convictions have been at the centre of debate in the United States, with some insisting on reforming the probation system and others calling for its total abolition.
