10.2 Degrees of Murder, Premeditation & Deliberation

Degrees of Murder, Premeditation & Deliberation

Doctrinal Foundation: At English common law, there were no degrees of murder. All unlawful killings committed with malice aforethought were simply "murder" and carried a mandatory sentence of capital punishment. To mitigate the severity of automatic capital sentencing, American legislatures—led by the Pennsylvania Statute of 1794—divided murder into First-Degree Murder and Second-Degree Murder. On the FYLSE, understanding the dividing lines between the degrees of murder, the mechanics of premeditation and deliberation, and the multifaceted limitations of the Felony Murder Rule (FMR) is essential for bar exam mastery.

I. Statutory Degrees of Murder

Modern penal statutes classify common law murders into two primary statutory grades:

                          ┌──────────────────────────────────────┐
                          │     Statutory Degrees of Murder      │
                          └──────────────────┬───────────────────┘
                                             │
         ┌───────────────────────────────────┴───────────────────────────────────┐
         ▼                                                                       ▼
 [FIRST-DEGREE MURDER]                                                  [SECOND-DEGREE MURDER]
1. Premeditated & Deliberate Killings                                   - All other common law murders
   - Cool-blooded reflection; prior design                                - Unpremeditated intent to kill
2. Heinous / Specific Statutory Means                                    - Intent for grievous bodily harm
   - Lying in wait, poison, torture, explosives                           - Depraved heart extreme recklessness
3. Statutory Enumerated Felonies (BARRK)                                 - Non-enumerated inherently dangerous
   - Burglary, Arson, Robbery, Rape, Kidnapping                             felony murders (majority rule)

1. First-Degree Murder: Three Recognized Categories

Under California Penal Code § 189 and standard modern penal codes, first-degree murder is strictly confined to three categories:

Category A: Premeditated and Deliberate Killings

A willful, deliberate, and premeditated killing requires proof of a specific intent to kill accompanied by cold-blooded reflection:

• Premeditation: Thinking about and planning the killing beforehand. While the quantity of time required to form premeditation can be relatively brief, the law demands an appreciable period of prior reflection.
• Deliberation: The decision to kill must be formed in a cool, calm, and dispassionate state of mind, capable of weighing the reasons for and against the choice. Deliberation cannot be formed in the throes of sudden unconsidered passion, violent panic, or frenzy.

[!IMPORTANT] The Anderson Evidentiary Framework (People v. Anderson, 70 Cal. 2d 612 (1968)): California courts evaluate whether premeditation and deliberation exist by assessing three types of evidence:

1. Planning Activity: Facts regarding what the defendant did prior to the killing showing preparation (e.g., obtaining a weapon, casing the location, laying a trap, following the victim);
2. Motive: Facts concerning the defendant's prior relationship or conduct with the victim showing a reason to kill (e.g., prior hostility, financial gain, jealousy, silencing a witness);
3. Manner of Killing: Facts showing that the physical mechanism of the killing was so particular, exacting, and calculated that the slayer must have acted pursuant to a preconceived design (e.g., execution-style shot to the temple, ligature strangulation, methodical poison administration).

Category B: Killings by Heinous, Atrocious, or Specific Statutory Means

Statutes explicitly elevate certain homicides to first-degree murder regardless of whether independent deliberation is proven, because the means employed inherently manifest calculated depravity:

• Poison: Methodical chemical administration implies stealth, concealment, and cold design;
• Lying in Wait: Requires concealment of purpose, a period of watching and waiting for an opportune moment, and a surprise assault from a position of advantage;
• Torture: Requires the intentional infliction of extreme and prolonged physical pain with a sadistic intent to cause suffering for revenge, extortion, persuasion, or personal gratification;
• Explosives, Destructive Devices, or Armor-Piercing Ammunition.

Category C: Statutory Enumerated Felony Murder (The BARRK Felonies)

Any killing occurring during the perpetration or attempted perpetration of specific felonies statutorily designated as first-degree predicates. The classic bar exam mnemonic is BARRK:

• Burglary;
• Arson;
• Robbery;
• Rape (and designated sexual assaults);
• Kidnapping. (California Penal Code § 189(a) also enumerates mayhem, carjacking, train wrecking, the specified sexual offenses, and murder by discharging a firearm from a motor vehicle at a person outside it; other modern codes list their own variants. Learn the mnemonic as the core, not as a closed list.)

2. Second-Degree Murder: The Residual Category

Second-degree murder encompasses all other common law murders that do not meet the statutory criteria for first-degree murder. Second-degree murder is established by:

1. Unpremeditated Intent to Kill: An intentional killing executed upon sudden impulse without cool deliberation or prior reflection;
2. Intent to Inflict Grievous Bodily Harm: Defendant intended to cause severe, disabling trauma, but did not premeditate a death;
3. Depraved Heart Murder: Extreme recklessness manifesting an abandoned and malignant heart and wanton indifference to human life;
4. Non-Enumerated Inherently Dangerous Felony Murder: A killing occurring during an inherently dangerous felony that is not specifically listed in the first-degree murder statute (e.g., manufacturing methamphetamine, shooting at an inhabited aircraft).

II. Working the Degree Ladder

1. "No Time Is Too Short" — and the Limit of That Slogan

Courts repeat that no particular period of time is required for premeditation; the reflection may occupy only moments. Read carelessly, that sentence erases the line between the degrees, because every intentional killing involves some decision. The controlling idea is qualitative rather than temporal: the question is whether the defendant actually reflected on the decision to kill, however briefly, or simply acted on an impulse that formed at the same instant as the killing. A killing that follows immediately on a sudden quarrel is second degree; the same killing after the defendant walked to the car, retrieved a weapon, and returned can be first, because the interval supplied an opportunity for reflection that the defendant used.

2. Intoxication and Mental Condition Move the Degree, Not the Verdict

Because premeditation and deliberation describe a specific mental state, evidence that the defendant was voluntarily intoxicated, or suffering a mental condition short of legal insanity, is admissible to show the state never formed. The effect is a reduction, not an acquittal: malice may still be established, so the killing remains murder and simply drops to the second degree. California states the principle cleanly in Penal Code section 29.4(b), which makes voluntary intoxication admissible "solely on the issue of whether or not the defendant actually formed a required specific intent, or, when charged with murder, whether the defendant premeditated, deliberated, or harbored express malice aforethought." The same evidence does nothing against a general-intent or implied-malice theory — which is precisely why it lands the defendant in second degree rather than out of the case.

3. Sorting Fact Patterns to Degrees

Scope reminder. The State Bar states that the FYLSX tests "legal theories and principles of general applicability" and that "[d]etailed knowledge of California-specific law is not required." Penal Code section 189 and People v. Anderson appear here as a well-drafted illustration of the standard American degree scheme — not because California trivia is tested. Where a question gives you a statute, apply the statute it gives you.
