"A conspiracy involves an agreement expressed or implied. A conspiratorial agreement is not a contract, not legally binding, because it is unlawful. But as an agreement it has its three stages, namely (1) making or formation (2) performance or implementation (3) discharge or termination. When the conspiratorial agreement has been made, the offence of conspiracy is complete, it has been committed, and the conspirators can be prosecuted even though no performance has taken place ... But the fact that the offence of conspiracy is complete at that stage does not mean that the conspiratorial agreement is finished with. It is not dead. If it is being performed, it is very much alive. So long as the performance continues, it is operating, it is being carried out by the conspirators, and it is governing or at any rate influencing their conduct. The conspiratorial agreement continues in operation and therefore in existence until it is discharged (terminated) by completion of its performance or by abandonment or frustration or however it may be."
