2. the designation of the offense by a statute

People v. Dela Cruz, G.R. No.137967 (2001)
   The non-inclusion of some of the names of the eyewitnesses
   in the information does not preclude the prosecutor from
   presenting them during trial.

PURPOSE: to safeguard the constitutional right of an accused
to be informed of the nature and cause of the accusation
against him so that he can duly prepare his defense.

Purpose: To inform the accused of the nature and cause of the
accusation against him, which is a constitutional right. The
objectives of the right are:
1) to furnish the accused with such a description of the charge
   against him as will enable him to make the defense
2) to avail himself of his conviction or acquittal for
   protection against further prosecution for the same cause;
3) to inform the court of the facts alleged, so that it may
   decided whether they are sufficient in law to support a
   conviction, if should be had.

NOTE: Substantial defect in the information cannot be cured by
evidence that would jeopardize the accused’s right to be
informed of the true nature of the offense he is charged with.
