Right to be Informed of the Nature and Cause of the Accusation Against Him (Sec. 14 (2), Art. III)

It is necessary that the offense which a person is accused of should be made known to him. The criminal complaint or information should be sufficiently clear to a person of ordinary intelligence as to what the charge is in order to enable him to prepare his defense.

In case of a violation of this right, the accused may challenged the validity and ask for the annulment of the proceedings before the proper court.
