Frequently Asked3
How does directing a weapon at a vital part allow inference of intent to kill?+
At common law, when a defendant intentionally uses a deadly weapon directed at a vital part of the victim's body, the factfinder may infer an intent to kill. This inference satisfies the malice aforethought element of murder. The neck, chest, head, and temple are recognized as vital areas because injury there is likely to prove fatal.
Supporting sources
Does the inference of intent to kill require proof that the defendant verbally expressed a desire to kill?+
No. The common-law inference arises from the objective circumstances of using a deadly weapon against a vital area. Direct evidence of subjective intent is not required. Circumstantial proof from the choice of weapon and target is sufficient.

Cases
Examples2
Forum Clause in Cruise Contract
Velocity Logistics and its passenger entered a ticket agreement containing a forum-selection clause. The clause was central to the parties' negotiations and pricing decisions. A court may treat the clause as a vital part of the agreement when assessing its enforceability.
Carnival Cruise Lines, Inc. v. Shute499 U.S. 585 (1991)
Forum Clause in Offshore Tow
Vortex Energy contracted with a German tug owner to tow its drilling rig across the Atlantic. The parties negotiated a London forum clause as a key term that shaped the monetary and risk allocations. A court may enforce the clause because it formed a vital part of the overall bargain.
Frequently Asked2
What makes an activity a vital part of a ship's operations under the Jones Act?+
An activity is a vital part when it is essential to the vessel's total operations and cannot lawfully be abandoned. Transporting injured seamen to medical care and unloading cargo have both been held to qualify. The employer remains liable for negligence in performing such tasks even when delegated to third parties.
Supporting sources
How does the vital-part concept affect enforcement of forum-selection clauses?+
When a forum clause is shown to have been a vital part of the parties' bargain, courts treat it as central to the negotiated terms and pricing. This factor supports enforcement absent a strong showing of unreasonableness. The clause's prominence in negotiations weighs heavily in the reasonableness analysis.
Can a defendant avoid the inference by claiming the act was only meant to frighten or wound?+
Post-act statements that the defendant intended only to scare the victim do not automatically negate the inference. The factfinder evaluates intent at the moment of the act based on the weapon, target, and manner of use. The jury may accept the inference despite later disclaimers.
