There are Four stages in commission of a Crime.
This is the first stage in commission of a crime. Intention to commit a crime is not punishable unless it is made known to others either by words or conduct. Eg: Waging a War against the Government is punishable. In this case, mere intention to commit is punishable. Similarly, mere assembly of persons to commit a dacoity is punishable even though there is no preparation to it.
It is difficult for the prosecution to prove that necessary preparation has been made for the commission of the offence. Eg: In case a person purchases a pistol and loads it with bullets, it is not possible to prove that the person is carrying the pistol to kill some other person.
In the Indian Law, Mere Preparation to commit an offense is punishable in the following offenses.
It is also known as the 'Preliminary Crime'. Section XXIII of the IPC, 1860 deals with 'of Attempt to Commit Offences' and provides the punishment for attempt.
This is the last stage in the commission of a crime. The accused is guilty of the offence only if he succeeds in his act. Otherwise, he is guilty of attempt only.
