TITLE ONE
CHAPTER I
Fundamental rights
Article 16
Only judicial authority can issue an arrest warrant. Such arrest warrant shall always be preceded by a formal accusation or charge of misconduct considered as criminal offence, punishable with imprisonment, provided that there is evidence to prove that a crime has been committed and that the defendant is criminally liable.
The authority executing an arrest warrant shall bring the accused before the judge without any delay and under its sole responsibility. Fail to comply with this provision will be punished under criminal law.
In cases of flagante delicto, any person may arrest the offender, turning him over without delay to the nearest authorities, which in turn, shall bring him before the Public Prosecution Service. A record of such arrest must be done immediately.
The Public Prosecution Service may order arrest of the accused, explaining the causes of such decision, only under the following circumstances all together: a) in urgent cases, b) when dealing with serious offence, c) under reasonable risk that the accused could evade the justice and, d) because of the time, place or circumstance, accused cannot be brought before judicial authority.
In cases of urgency or flagrancy, the judge before whom the prisoner is presented shall immediately confirm the arrest or order his release, according to the conditions established in the law.
