What are the stages of felony?
ART. 6. Consummated, frustrated, and attempted felonies. - Consummated felonies, as well as those which are frustrated and attempted, are punishable.
A felony is consummated when all the elements necessary for the for its execution and accomplishment are present; and it is frustrated when the offender performs all the acts of execution which would produce the felony as a consequence but which, nevertheless, do not produce it by reason or causes independent of the will of the perpetrator.
There is an attempt when the offender commences the commission of a felony directly by overt acts, and does not perform all the acts of execution which should produce the felony by reason of some cause or accident other than his own spontaneous desistance.
Based on the foregoing provision, the distinctions between frustrated and attempted felony are summarized as follows:1.) In frustrated felony, the offender has performed all the acts of execution which should produce the felony as a consequence; whereas in attempted felony, the offender merely commences the commission of a felony directly by overt acts and does not perform all the acts of execution.
2.) In frustrated felony, the reason for the non-accomplishment of the crime is some cause independent of the will of the perpetrator; on the other hand, in attempted felony, the reason for the non- fulfillment of the crime is a cause or accident other than the offender's own spontaneous desistance.[1]
