The Indeterminate Sentence Law of 1933 lets courts impose a range of imprisonment (minimum and maximum) and allows parole after the minimum term, except for certain serious offenses. A Board of Indeterminate Sentence evaluates prisoners for parole and oversees their release and supervision.

Who it affects: It applies to persons convicted of offenses punishable by Philippine statutes (excluding those listed in Section 2) who are sentenced to more than one year of imprisonment.

Key provisions

  • Indeterminate sentencing framework. Courts must set a minimum term that is at least the statutory minimum and a maximum term that does not exceed the statutory maximum; after serving the minimum, a prisoner may be released on parole under this Act. [Section 1]
  • Offenses excluded from the Act. The law does not apply to death‑penalty or life‑imprisonment cases, treason‑related crimes, sedition, espionage, piracy, habitual delinquents, escapees, those who broke a conditional pardon, offenses with a maximum term of one year or less, and persons already sentenced before the Act took effect (except as provided in Section 5). [Section 2]
  • Creation of the Board of Indeterminate Sentence. A Board is created, chaired by the Secretary of Justice and composed of four members appointed by the Governor‑General with Senate consent; the board must include a sociologist, a clergyman or educator, a psychiatrist (or employ one), and at least one woman. [Section 3]
  • Board compensation and rules. Each board member receives ten pesos per meeting, not exceeding one thousand pesos per year, plus actual travel expenses; the board may adopt its own meeting rules and procedures. [Section 4]
  • Parole eligibility criteria. After a prisoner serves the minimum term, the Board may grant parole if the prisoner’s work and conduct reports show he is fit for release, likely to remain law‑abiding, and not a danger to society. [Section 5]
  • Parole supervision. Paroled prisoners must report to parole officers designated by the Board for a surveillance period equal to the remaining maximum sentence or until the Board issues a final release certificate; the Board may set and change residence limits. [Section 6]
  • Consequences of parole violation. If a parolee breaks any parole condition or commits a new crime and is convicted, he is re‑arrested and must serve the remaining unexpired portion of the original maximum sentence unless the Board grants a new parole. [Section 8]
  • Benefits for parolees. A prisoner released on parole is entitled to the benefits listed in Section 1751 of the Revised Administrative Code. [Section 10]
