Section 2
SEC. 2. The fiscal of any province may, if he deems it wise, conduct investigations of crimes and misdemeanors by taking oral evidence of reputed witnesses, and for this purpose may issue subpoenas summoning witnesses to appear and testify under oath before him. and the attendance or evidence of absent or recalcitrant witnesses may be enforced by application to the justice of the peace of the municipality in which the investigation is being held, or the Court of First instance of the province. No witness summoned to testify under this section shall be under obligation to give testimony tending to criminate himself. This section shall not be construed to authorize a provincial fiscal to act as justice of the peace in any preliminary investigation, but only as authorizing him to secure the attendance of witnesses before him in making necessary investigation for the purpose of instituting or carrying on criminal prosecutions. For the purposes named in this section each provincial fiscal is hereby authorized to administer oaths.
