⚡ 10-Second Rule
Getting drunk on purpose only helps if the crime needed a plan your foggy brain truly couldn't form.
🧒 ELI-10 Scene
After ten rounds of the spinning game, Dev is dizzy and giggling. Ask him to run the scavenger hunt — pick teams, hide clues, plan routes — and he simply can't. His brain won't build a plan. But if dizzy Dev stumbles around swinging his arms and smacks his cousin, nobody says "the spinning excuses it." He chose to spin. Fuzzy heads can erase careful plans, but they never excuse plain reckless flailing.
⚖️ Actual Rule
Voluntary intoxication — self-induced by a substance the defendant knows can intoxicate — is, under the majority rule, a defense only to specific intent crimes, and only when the intoxication actually prevented the defendant from forming the required specific intent. It may also negate the premeditation and deliberation required for first-degree murder, reducing the charge to second-degree. It is no defense to general intent crimes, malice crimes, crimes of recklessness or negligence, or strict liability offenses; the choice to become intoxicated is itself viewed as reckless. Paraphrasing MPC § 2.08: intoxication is relevant only when it negates an element of the offense, and when recklessness suffices, unawareness of a risk due to voluntary intoxication is no excuse. A defendant who drinks to build the nerve to commit the crime gets no defense at all. Involuntary intoxication — substances taken without knowledge of their nature, under duress, or as an unanticipated reaction to prescribed medication — is treated like a mental disease: it excuses the crime entirely if it leaves the defendant unable to satisfy the jurisdiction's insanity test at the time of the act.
[NJ-VARIANT: flagged for future Eli Explains NJ Law module] ELI-10 translation: chosen drunkenness can only erase a required plan; unchosen drunkenness is judged like a sick mind.
🔍 Ask These Questions
- Was the intoxication voluntary or involuntary? (Did the person choose the substance, knowing what it does?)
- If involuntary, apply the insanity framework to the moment of the act. (Treat the surprise poisoning like a temporarily broken mind.)
- If voluntary, is the charged crime specific intent? (Only plan-crimes can be erased by a chosen fog.)
- Did the intoxication actually prevent forming that intent? (Being drunk isn't enough; the plan must have been truly impossible.)
- Is the charge general intent, malice, recklessness, or strict liability? If so, the defense fails. (For every non-plan crime, chosen drunkenness is no help.)
- Did the defendant drink for courage to commit the crime? (Drinking to work up the nerve kills the defense completely.)
⚠️ Bar Trap
Exam language: Examiners offer voluntary intoxication as a defense to a general intent crime, a malice crime such as arson or common-law murder, or a recklessness-based offense — where it is categorically unavailable. The mirror trap runs the other way: testers make the defendant merely tipsy and invite you to negate a specific intent the defendant plainly still formed.
ELI-10: First name the crime's thinking-level, then ask if the fog was thick enough. Drunkenness never excuses act-crimes or careless-crimes, only truly unformed plans.
🧪 Question
At a holiday party, a man drank a dozen shots of whiskey over two hours. Stumbling home well past midnight, he pried open the window of a darkened house that he believed, in his profound confusion, to be his own, climbed inside, and passed out on the living room couch. In fact the house belonged to a stranger. The man is charged with common-law burglary, defined in the jurisdiction as breaking and entering the dwelling of another at night with the intent to commit a felony therein. Expert testimony establishes that his blood alcohol level rendered him incapable of forming any purpose beyond finding a place to sleep.
What is the man's strongest argument against the burglary charge?
(A) His voluntary intoxication negated the intent to commit a felony inside, an element of the offense. (B) His voluntary intoxication rendered the breaking and entering involuntary acts. (C) Intoxication is a complete defense to any crime committed while too impaired to appreciate wrongdoing. (D) The charge fails because he lacked a motive to steal from a stranger.
Answer: (A). Burglary is a specific intent crime requiring intent, at entry, to commit a felony inside. His extreme intoxication prevented him from forming any such intent — he meant only to sleep in what he thought was his own home — so an essential element is missing.
💡 Why the Wrong Answers Are Wrong
- (B) confuses impaired judgment with involuntariness; his climbing through the window was a willed bodily movement.
- (C) overstates the doctrine — voluntary intoxication is never a general excuse and never reaches non-specific-intent crimes.
- (D) relies on motive, which is not an element of burglary and need never be proved.
- ELI-10: The misconception is treating drunkenness as one all-purpose excuse. It is only a scalpel that removes missing plans.
