CHAPTER 2 Fundamental Human and Civil Rights and Freedoms

Article 42. A person shall not be compelled to be a witness against himself or herself or against his or her spouse, or against a close relative.

A punishment may not exceed that which could have been met by the law in effect when the crime was committed. A person shall not be considered to be guilty for a crime if at the time of its commission the act was not legally considered a crime. Laws limiting or increasing liability shall not have retroactive effect.
