What is the legal test for a charge of conspiracy to commit second-degree murder?

In deciding it, I would adhere to this court's view in People v. Horn (1974) 12 Cal.3d 290, 115 Cal.Rptr. 516, 524 P.2d 1300, that conspiracy to commit first degree murder and conspiracy to commit second degree murder are separate crimes distinguished by whether the intent to kill reflected in the conspirators' agreement is deliberate and premeditated or not. I would further conclude that under the Penal Code, each type of conspiracy to murder is subject to the punishment prescribed for the corresponding degree of murder.
