P.R. Laws tit. 1, § 594
Once the order has been dictated and the immunity granted the witness may not refuse to comply with said order invoking his/her privilege against self-incrimination. No testimony or information obtained from said witness in compliance with the order, nor any other evidence obtained directly or indirectly after that testimony or information, may be used against the witness in any criminal proceeding against him/her, except in a perjury proceeding for giving false testimony when testifying in compliance with the order. If after the testimony offered in compliance with the order a criminal action is filed against the witness, the public prosecutor must establish beyond a reasonable doubt that neither knowledge of the crime, nor the evidence for the prosecution were directly or indirectly obtained through the testimony or the information given by the witness in compliance with the order. If the witness were to have obtained transactional, civil or administrative immunity or all the aforesaid, every process already initiated shall be dismissed and no process whatsoever affected by the immunity will be initiated.
