What Is Kidnapping Under California Law?
Kidnapping is the unlawful confinement of another person that involves either significant movement (asportation) or concealment in a secret place. California Penal Code § 207(a) defines simple kidnapping as unlawfully moving another person by force or fear a “substantial distance.” Penal Code § 209 separately defines aggravated kidnapping — kidnapping combined with robbery, rape, carjacking, extortion, or ransom — and carries a mandatory life sentence.
California’s approach is genuinely unusual, and the California Bar Exam tests it precisely because it differs from both the common law and the Model Penal Code: California uses two different asportation tests, depending on which tier of kidnapping is charged.
California’s Two-Tier Asportation Test
This is the single most important thing to know about California kidnapping law. Simple kidnapping and aggravated kidnapping do not share the same movement standard:
- Simple kidnapping (§ 207(a)): uses the People v. Martinez totality-of-the-circumstances test — asking whether the movement was “substantial in character,” considering the actual distance, whether it increased the risk of harm, decreased the likelihood of detection, or increased the danger of the victim’s foreseeable escape attempts. There is no fixed minimum distance.
- Aggravated kidnapping (§ 209): uses the older, stricter People v. Daniels test — the movement must not be merely incidental to the underlying felony (robbery, rape, etc.) and must substantially increase the risk of harm beyond what is inherent in that felony.
Applying the lenient Martinez standard to an aggravated-kidnapping fact pattern, or vice versa, is one of the most common and serious errors on California-flagged essays.
The Incidental-Movement Trap
Bar examiners love pairing kidnapping with another crime — usually robbery or rape — plus some movement of the victim, to test whether that movement is independently substantial or merely incidental to the other offense. A defendant who forces a victim into a car to drive three blocks for a robbery has moved the victim, but the movement does not independently increase danger beyond the robbery itself, so kidnapping may not apply. A defendant who drives a robbery victim across state lines to a hideout has clearly moved the victim in a way that increases danger and duration of confinement, supporting an independent kidnapping charge.
Asportation vs. Secret Confinement
Two alternative conduct routes satisfy kidnapping: moving the victim a meaningful distance (asportation), or hiding the victim in a concealed location without significant movement at all (secret confinement). Consent obtained by force, threat, or fraud is not valid consent — a victim tricked into “voluntary” movement under false pretenses has still been kidnapped once the deception is discovered and confinement continues against her will.
Comparing California’s Two Kidnapping Tiers
| Factor | Simple kidnapping (§ 207(a)) | Aggravated kidnapping (§ 209) |
|---|---|---|
| Underlying felony required? | No | Yes (robbery, rape, carjacking, extortion, ransom) |
| Governing test | Martinez — totality of circumstances, “substantial in character” | Daniels — not incidental to, and substantially increases risk beyond, the underlying felony |
| Minimum distance | None fixed | None fixed, but movement must be independently significant |
| Sentence | Standard felony range | Mandatory life sentence |
Kidnapping vs. False Imprisonment
False imprisonment is the lesser-included offense of kidnapping: it requires only unlawful confinement, with no asportation or concealment required. If a defendant is charged with kidnapping but the evidence proves only confinement without substantial movement, kidnapping fails but false imprisonment remains available. This lesser-greater relationship is regularly tested on sufficiency-of-the-evidence questions.
Worked Example: The Bar Exam Fact Pattern
Don points a gun at Harriet on her porch and says, “Come with me.” Harriet does not move. Police arrive and arrest Don before any movement occurs. Don later claims the gun was a toy.
Analysis: Attempted kidnapping requires specific intent to kidnap plus a substantial step toward that objective. Pointing the gun and ordering Harriet to come with him constitutes a substantial step, so Don is guilty of attempted kidnapping even though Harriet never actually moved. Don’s belief that the gun was a toy is factual impossibility, which is never a defense to attempt.
Common Law and MPC Contrasts
The Model Penal Code, under § 212.1, requires that the movement or confinement serve one of several enumerated unlawful purposes (ransom, terrorism, facilitating a felony, among others) and go beyond what is merely incidental to another offense — a purpose-driven framework rather than a pure distance inquiry. California’s statutory scheme instead splits kidnapping into two tiers with two different asportation tests, without requiring proof of one of the MPC’s enumerated purposes for simple kidnapping under § 207(a). Bar candidates studying multiple jurisdictions should not import the MPC’s purpose requirement into a California fact pattern.
Frequently Asked Questions
What is the difference between simple and aggravated kidnapping in California?
Simple kidnapping under Penal Code § 207(a) requires only substantial movement by force or fear. Aggravated kidnapping under § 209 requires that the kidnapping accompany another felony like robbery or rape, and applies the stricter Daniels asportation test.
How far must a victim be moved to satisfy kidnapping in California?
There is no fixed minimum distance. Under People v. Martinez, courts ask whether the movement was “substantial in character” given the totality of the circumstances, including whether it increased danger or decreased the likelihood of detection.
Can a defendant be convicted of kidnapping if the victim never actually moved?
Yes, as an attempt. If the defendant took a substantial step toward confining or moving the victim — such as forcing them at gunpoint toward a vehicle — attempted kidnapping is viable even without completed movement.
Key Takeaways
- California Penal Code § 207(a) governs simple kidnapping; § 209 governs aggravated kidnapping combined with robbery, rape, carjacking, or ransom.
- Simple kidnapping uses the flexible Martinez totality-of-the-circumstances test; aggravated kidnapping uses the stricter Daniels incidental-movement test.
- Movement that is merely incidental to another crime does not independently support a kidnapping conviction.
- False imprisonment is kidnapping’s lesser-included offense, requiring confinement but not movement.
- Consent obtained through force, threat, or fraud does not defeat a kidnapping charge.
