Ticket of leave, which was a document issued to prisoners granting them conditional release, was a commonly used term during the 19th and early 20th centuries. In modern times, this term has been replaced by several synonymic terms, such as 'parole', 'early release', 'conditional release', and 'probation'. These new terms indicate the same concept of releasing prisoners before the completion of their sentence, based on certain conditions. The practice of ticket of leave may not exist anymore, but the concept remains relevant in the contemporary prison system. It is essential to continue evolving the prison system and providing effective measures for rehabilitation and reintegration of offenders back into society.
