"You will observe that, to constitute murder in the first degree, the act causing death must have been perpetrated from premeditated design. Premeditated design to kill means intent to kill. "Design" means intent, and both words essentially imply premeditation or design formed before the act. The premeditation of the statute does not exclude sudden intent, and need not be slow or last long." (Eckman v. State, 191 Wis. 63 (1926))

“I find he manifested an intent to kill, but it was a sudden intent to kill at the time of his swinging,” the judge said. (Los Angeles Times)
