CALIFORNIA CRIMINAL LAW AND PROCEDURE DISTINCTIONS
California criminal law is statutory — the Penal Code defines the offenses — and while it tracks common-law concepts of homicide, theft, and inchoate crimes, it departs from the national/majority approach in several heavily tested ways. The biggest recent changes are reformatory: Senate Bill 1437 dramatically narrowed felony murder and abolished the natural-and-probable-consequences theory of murder, and Proposition 47 reclassified many theft and drug felonies as misdemeanors. California also defines burglary far more broadly than the common law, requires an overt act for conspiracy, and bars conviction on uncorroborated accomplice testimony. On the procedure side, Proposition 8 conforms California search-and-seizure and confession law to the federal standard. This page isolates those Penal Code and procedural departures; the universal elements of crimes and the federal constitutional-criminal-procedure framework are in the MBE outline.
📘 This page covers only California's departures from national/majority law. For the full doctrine, see the MBE Criminal Law & Procedure Long Outline.
I. HOMICIDE — MURDER, DEGREES, AND FELONY MURDER
California's homicide statutes define malice and the degrees of murder by code, and recent reform sharply limited the felony-murder and accomplice-liability theories.
A. Malice and the Degrees of Murder (Penal Code §§ 187–189)
CA Rule: Penal Code § 187 defines murder as the unlawful killing of a human being (or fetus) with malice aforethought. Malice may be express (intent to kill) or implied (no considerable provocation, or an abandoned and malignant heart — the California formulation of depraved-heart murder). Section 189 divides murder into first degree (willful, deliberate, premeditated killing; killing by specified means such as poison, lying in wait, torture; or killing in the commission of an enumerated felony) and second degree (all other murder). National: same general structure, but California's statutory definition of implied malice and its enumerated first-degree felonies are code-specific. California: apply the Penal Code definitions of express/implied malice and the § 189 degree categories.
B. Felony-Murder Reform — SB 1437 (Penal Code § 189(e))
CA Rule: Senate Bill 1437 (effective 2019) fundamentally narrowed felony murder. Under Penal Code § 189(e), a participant in the underlying felony is liable for murder only if the person (1) was the actual killer; (2) was not the actual killer but, with intent to kill, aided and abetted the actual killer; or (3) was a major participant in the felony who acted with reckless indifference to human life. SB 1437 also abolished the natural-and-probable-consequences doctrine as a basis for murder liability, and Penal Code § 1170.95/§ 1172.6 allows resentencing of those convicted under the old theories. National: the traditional felony-murder rule imposes murder liability on all participants for any death during an inherently dangerous felony, regardless of individual mens rea. California: liability now requires actual killing, intent, or major participation with reckless indifference.
EXAMPLE: Two people commit a robbery; one unexpectedly shoots and kills the victim. Under traditional felony murder, both are guilty of murder. Under SB 1437, the non-shooter is guilty of murder only if he intended to kill or was a major participant who acted with reckless indifference to human life; otherwise he is not guilty of murder (though he remains liable for the robbery).
C. Implied-Malice "Watson" Murder (DUI)
CA Rule: Under People v. Watson (1981), a defendant who drives under the influence and kills can be convicted of second-degree murder on an implied-malice theory if the defendant knew of the life-endangering risk (often shown by a prior DUI conviction and a "Watson advisement") and acted with conscious disregard for human life. National: most states would charge vehicular manslaughter or DUI homicide. California: a repeat or aggravated DUI killing can be charged as implied-malice murder.
ESSAY WRITING TIP: For homicide, start with § 187 malice, classify express vs. implied, then apply § 189 to fix the degree. If a felony killing is involved, run the SB 1437 § 189(e) test (actual killer / intent / major participant with reckless indifference) and remember the natural-and-probable-consequences theory is gone for murder. For a DUI death with prior knowledge of risk, raise Watson implied-malice murder.
CA BAR TIP: SB 1437 is the most important recent California criminal-law change — examiners love it. Do not apply the old all-participants felony-murder rule; require the § 189(e) mental state for accomplices. And remember natural-and-probable-consequences still supports lesser crimes, just not murder.
II. MANSLAUGHTER
California codifies the manslaughter categories with its own definitions.
A. Voluntary, Involuntary, and Vehicular (Penal Code § 192)
CA Rule: Penal Code § 192 defines manslaughter as the unlawful killing without malice and identifies three kinds: voluntary (upon a sudden quarrel or heat of passion), involuntary (in the commission of an unlawful act not amounting to a felony, or a lawful act done without due caution), and vehicular (killings arising from driving). Notably, California's involuntary-manslaughter statute by its terms excludes acts committed in the driving of a vehicle, which are handled under the separate vehicular-manslaughter provisions. National: heat-of-passion voluntary and criminal-negligence involuntary manslaughter are general concepts. California: the three statutory categories and the vehicular carve-out are code-specific.
ESSAY WRITING TIP: Distinguish the three § 192 categories explicitly. For a sudden-quarrel killing, analyze adequate provocation and lack of cooling time for voluntary manslaughter; for a careless killing, use involuntary manslaughter unless a vehicle is involved, in which case shift to vehicular manslaughter.
CA BAR TIP: Watch the vehicle distinction — a negligent driving death is vehicular manslaughter (or Watson murder if aggravated), not ordinary involuntary manslaughter, because § 192 carves driving out of the involuntary category.
III. THEFT CRIMES — CONSOLIDATION AND PROP 47
California consolidated the common-law acquisitive offenses and then, by initiative, reclassified many theft felonies as misdemeanors.
A. Theft Consolidation and Thresholds (Penal Code §§ 484, 487, 488)
CA Rule: Penal Code § 484 consolidates larceny, embezzlement, larceny by trick, and false pretenses into a single crime of "theft." Section 487 defines grand theft (generally property valued over $950, or specified property like a firearm or automobile), while § 488 defines petty theft (value of $950 or less). National: many states retain separate larceny/embezzlement/false-pretenses offenses. California: one consolidated theft crime graded by value, with the $950 grand/petty line.
B. Proposition 47 Reclassification
CA Rule: Proposition 47 (2014) reclassified a range of low-level theft and drug offenses as misdemeanors rather than felonies — including most thefts of $950 or less (creating "shoplifting" under Penal Code § 459.5), petty theft, receiving stolen property under $950, forging/passing small checks, and simple drug possession — and allows resentencing of those previously convicted. It also created the § 459.5 offense of shoplifting (entering an open commercial establishment during business hours with intent to commit larceny of $950 or less), which must be charged instead of burglary. National: theft and drug felony thresholds vary, generally higher exposure. California: many former felonies are now misdemeanors, and shoplifting displaces burglary for small in-store thefts.
EXAMPLE: A defendant walks into an open store during business hours intending to steal merchandise worth $200. Under Proposition 47 this is shoplifting (Penal Code § 459.5), a misdemeanor — it cannot be charged as commercial burglary even though the entry-with-intent elements of burglary are met.
ESSAY WRITING TIP: For acquisitive-crime essays, identify the single consolidated theft offense (§ 484), fix grand vs. petty using the $950 line (§§ 487/488), and apply Proposition 47 to determine whether the crime is a misdemeanor. If the facts show entry of an open store to steal $950 or less, charge § 459.5 shoplifting rather than burglary.
CA BAR TIP: Proposition 47's $950 threshold and the shoplifting/burglary interplay are favorite tested points. Do not over-charge a minor in-store theft as commercial burglary; § 459.5 controls.
IV. BURGLARY — BROAD DEFINITION (Penal Code § 459)
California's burglary statute is far broader than the common-law crime.
A. No Breaking, Any Structure, Day or Night
CA Rule: Penal Code § 459 defines burglary as entering any house, room, apartment, shop, warehouse, store, vehicle (when locked), or other specified structure with intent to commit grand or petit larceny or any felony. There is no breaking requirement, no requirement that the structure be a dwelling, and no nighttime requirement — and California recognizes first-degree burglary (inhabited dwelling) and second-degree burglary (all other) under § 460. National: common-law burglary requires breaking and entering the dwelling of another at night with intent to commit a felony. California: entry alone (no breaking) of a wide range of structures, day or night, with intent to commit larceny or any felony, suffices — though Prop 47's § 459.5 shoplifting carve-out applies to open commercial premises.
ESSAY WRITING TIP: Apply § 459 element by element — entry (not breaking), of a covered structure, with the intent formed at the time of entry to commit larceny or any felony. Then classify first vs. second degree under § 460, and check whether Prop 47 shoplifting (§ 459.5) displaces a burglary charge for a small theft from an open store.
CA BAR TIP: The absence of breaking and nighttime requirements is the recurring trap. A person who walks through an unlocked door of any structure intending to commit a felony commits California burglary. Just confirm the felonious intent existed at entry.
V. ROBBERY AND OTHER OFFENSES
CA Rule: Penal Code § 211 defines robbery as the felonious taking of personal property in the possession of another, from the person or immediate presence, against the will, accomplished by force or fear. California recognizes degrees of robbery (§ 212.5). California also follows the "Estes robbery" rule, under which force or fear used to retain property or effect escape during a continuing theft can elevate a theft to robbery. National: general robbery elements are similar. California: the continuing-offense/Estes approach and the statutory degree scheme are the code-specific points.
ESSAY WRITING TIP: For robbery, confirm the taking was from the person or immediate presence by force or fear, and remember that under Estes, force used during the asportation or escape phase of a theft can convert it into robbery even if no force accompanied the initial taking.
CA BAR TIP: If force or fear appears only when the thief is confronted while leaving, do not dismiss robbery — California's continuing-offense view (Estes) may still make it robbery.
VI. INCHOATE CRIMES AND ACCOMPLICE RULES
California requires an overt act for conspiracy and bars conviction on uncorroborated accomplice testimony.
A. Conspiracy Requires an Overt Act (Penal Code §§ 182, 184)
CA Rule: Penal Code § 184 requires that, in addition to the agreement, at least one of the conspirators commit an overt act in furtherance of the conspiracy before the crime is complete. National: the common law (and some states) require no overt act; the agreement alone completes conspiracy, though many modern statutes require one. California: an overt act by any conspirator is required.
B. Accomplice-Corroboration Rule (Penal Code § 1111)
CA Rule: Penal Code § 1111 provides that a conviction cannot be based on the testimony of an accomplice unless it is corroborated by other evidence tending to connect the defendant with the offense; the corroboration may not come from another accomplice. National: at common law and in many states, a conviction may rest on uncorroborated accomplice testimony (with a cautionary instruction). California: corroboration is mandatory.
C. Abolition of Common-Law Crime Distinctions
CA Rule: California has largely abolished the common-law distinctions among principals and accessories before the fact — all who aid, abet, or directly commit the crime are principals (Penal Code § 31) — while accessories after the fact (§ 32) are treated as a separate, lesser offense. National: modern jurisdictions have similarly merged parties. California: § 31 principals vs. § 32 accessories-after-the-fact is the statutory framework.
ESSAY WRITING TIP: For conspiracy, always state and apply the overt-act requirement (§ 184) — the agreement alone is not enough in California. When the prosecution's case rests on a co-participant's testimony, raise the § 1111 corroboration requirement; uncorroborated accomplice testimony cannot sustain a conviction.
CA BAR TIP: The overt-act and accomplice-corroboration rules are easy points that candidates forget. If a fact pattern leans on a snitch co-defendant, flag § 1111 corroboration; if a conspiracy charge appears, confirm an overt act occurred.
VII. CRIMINAL PROCEDURE — PROPOSITION 8 CONFORMITY
California criminal procedure largely conforms to the federal constitutional standard because of Proposition 8.
A. Truth in Evidence (Cal. Const. Art. I, § 28(f))
CA Rule: Proposition 8 (1982) added the "Truth in Evidence" provision, the practical effect of which is that California applies federal Fourth Amendment (search and seizure), Fifth Amendment (Miranda/confessions), and Sixth Amendment (right to counsel, confrontation, identification) standards in criminal cases; California courts may no longer suppress relevant evidence under a broader independent state ground. National: federal constitutional-criminal-procedure standards apply. California: post-Prop 8, the state floor matches (does not exceed) the federal standard for suppression — apply the federal analysis directly.
ESSAY WRITING TIP: On a California suppression issue, run the standard federal Fourth/Fifth/Sixth Amendment analysis (warrant requirement and exceptions, custodial-interrogation Miranda, right to counsel) and note that Proposition 8 prevents California from suppressing on any broader independent state ground. Statutory exclusionary rules (e.g., wiretap statutes) survive Prop 8; constitutional state-ground suppression does not.
CA BAR TIP: This is the inverse of California's usual "we protect more" posture — for criminal evidence, Prop 8 pulls California down to the federal standard. Do not invent a broader California suppression rule.
VIII. PUNISHMENT AND SPECIAL CIRCUMSTANCES
CA Rule: First-degree murder is punishable by death or life without parole only when a statutory special circumstance (Penal Code § 190.2) is found — for example, multiple murders, murder for financial gain, murder of a peace officer, or felony murder accompanied by the SB 1437 mental state. Note that as a practical matter California's death penalty has been under an executive moratorium since 2019, and capital cases continue to be litigated but executions are suspended. National: death-penalty availability and aggravators vary widely by state. California: the § 190.2 special-circumstances framework governs death eligibility, with executions currently on hold.
ESSAY WRITING TIP: If an essay raises capital exposure, identify the § 190.2 special circumstance and tie felony-murder special circumstances to the SB 1437 mental-state requirement (major participant acting with reckless indifference). Mention the current execution moratorium for completeness.
CA BAR TIP: Death eligibility requires a pleaded and proven special circumstance — first-degree murder alone is not enough. Connect this to SB 1437 when the theory is felony murder.
IX. CALIFORNIA DISTINCTIONS CHECKLIST
- Murder is statutory (Penal Code §§ 187–189) with express/implied malice and first/second-degree categories; first-degree includes enumerated-felony killings.
- SB 1437 (Penal Code § 189(e)) limits felony murder to the actual killer, an intent-to-kill aider, or a major participant acting with reckless indifference; it abolished natural-and-probable-consequences as a theory of murder (resentencing under § 1172.6).
- Watson implied-malice second-degree murder applies to aggravated/repeat DUI killings.
- Manslaughter (Penal Code § 192) has voluntary, involuntary, and vehicular categories; involuntary excludes vehicle killings (handled as vehicular manslaughter).
- Theft is consolidated (§ 484); grand vs. petty turns on the $950 line (§§ 487/488).
- Proposition 47 reclassified many theft/drug felonies as misdemeanors and created shoplifting (§ 459.5), which displaces burglary for entry of an open store to steal $950 or less.
- Burglary (§ 459) requires no breaking, no dwelling, and no nighttime — just entry of a covered structure with intent to commit larceny or any felony (degrees under § 460).
- Robbery (§ 211) follows the continuing-offense/Estes rule: force or fear to retain property or escape can elevate theft to robbery.
- Conspiracy requires an overt act (Penal Code § 184).
- A conviction cannot rest on uncorroborated accomplice testimony (Penal Code § 1111).
- All who aid, abet, or commit are principals (§ 31); accessories after the fact are a separate lesser offense (§ 32).
- Proposition 8 (Art. I, § 28(f)) conforms California search-and-seizure, Miranda, and counsel standards to federal law; no broader state-ground suppression.
- Death eligibility requires a § 190.2 special circumstance; executions are currently under a moratorium.
