MPC: The Tension Between the Rejection of Factual Impossibility and the Strong Corroboration Requirement
Consider the MPC’s substantial step test.
The original formulation says that a defendant must purposely engage in conduct that, under the circumstances as he believes them to be, constitutes a substantial step.
It later says that conduct is not a substantial step under the above formulation unless it is strongly corroborative of the defendant’s criminal purpose.
This creates some ambiguity as to what set of facts “strongly corroborative” is evaluated under.
A natural reading may say to evaluate it in the defendant’s belief-world, because then the second requirement is merely defining substantial step, which is then modified by the “circumstances as he believes them”
But that would make the strongly corroborative requirement basically meaningless, because you could get acts that do not strongly corroborate the purpose at all (like snapping your fingers or telling the truth) to be defined as substantial steps (if the defendant believes that snapping their fingers kills somebody or that the truth is actually a false statement).
So what is the best way to read the strongly corroborative language?
