Alaska Criminal Law: Felonies, Misdemeanors, and Infractions

Alaska's criminal law framework organizes offenses into three principal tiers — felonies, misdemeanors, and infractions — each carrying distinct procedural consequences, sentencing ranges, and collateral effects. This classification structure governs how charges are filed, which courts hold jurisdiction, and what penalties attach upon conviction. The Alaska Statutes (Title 11 and Title 12) and the Alaska Rules of Criminal Procedure establish the operative boundaries that define how the criminal justice system processes offenses from citation through sentencing.

Definition and scope

Alaska criminal law draws its foundational classification scheme from AS Title 11 (Criminal Law) and AS Title 12 (Code of Criminal Procedure), administered through the Alaska Court System and prosecuted by the Alaska Department of Law. The three-tier taxonomy works as follows:

Felonies are the most serious category, subdivided into four classes under AS 11.81.250:
1. Unclassified felonies — reserved for the gravest offenses (e.g., murder in the first degree); no standard statutory maximum applies because sentences may include life imprisonment.
2. Class A felonies — carry a maximum sentence of 20 years under AS 12.55.125(c).
3. Class B felonies — carry a maximum sentence of 10 years under AS 12.55.125(d).
4. Class C felonies — carry a maximum sentence of 5 years under AS 12.55.125(e).

Misdemeanors are divided into two classes under AS 11.81.250:
1. Class A misdemeanors — maximum sentence of 1 year under AS 12.55.135(a).
2. Class B misdemeanors — maximum sentence of 90 days under AS 12.55.135(b).

Infractions are civil violations under AS 11.81.900(b)(18), punishable by fines only, carrying no possibility of incarceration and no criminal record attachment.

Scope, coverage, and limitations: This page addresses Alaska state criminal law as defined under Alaska Statutes and enforced in Alaska state courts. Federal criminal offenses prosecuted in the U.S. District Court for the District of Alaska fall under Title 18 of the United States Code and are not covered here. Tribal criminal jurisdiction — exercised through Alaska Native tribal courts — operates under separate sovereign authority and is addressed in that dedicated resource. Juvenile matters are governed by the separate Alaska Juvenile Justice System framework rather than the adult criminal classification described on this page.

How it works

The Alaska criminal procedure framework, detailed in the Alaska Rules of Criminal Procedure, structures the process through discrete stages that differ based on offense classification.

Charging and arraignment: Felonies are typically initiated by grand jury indictment or a preliminary hearing to establish probable cause under Alaska R. Crim. P. 5.1. Misdemeanors may be charged by information filed directly by a prosecutor. Infractions are issued as citations.

Court jurisdiction by offense class:
- Felonies are heard in the Alaska Superior Court.
- Misdemeanors are heard in the Alaska District Court.
- Infractions are handled administratively or in District Court without jury trial rights.

Bail and pretrial detention: Under AS 12.30.011, a defendant charged with an unclassified or Class A felony may be detained without bail if the court finds clear and convincing evidence that no conditions would reasonably protect the public.

Plea and trial rights: Defendants charged with felonies or Class A misdemeanors hold a constitutional right to jury trial under Alaska Constitution Article I, Section 11. Class B misdemeanor defendants and infraction recipients do not hold the same jury trial entitlement.

Sentencing: The Alaska Sentencing Guidelines, maintained by the Alaska Court System and informed by AS 12.55, prescribe presumptive ranges for felonies. Judges may impose aggravated or mitigated terms supported by specific statutory factors. Misdemeanor sentences fall within the statutory maximums noted above, with judicial discretion largely unrestricted by presumptive ranges. The full sentencing structure is documented in the Alaska sentencing guidelines reference.

Common scenarios

The three-tier classification surfaces across a predictable range of criminal matter types:

• DUI (Driving Under the Influence): A first DUI offense is a Class A misdemeanor under AS 28.35.030(n). A third DUI within 10 years becomes a Class C felony, triggering felony procedural requirements and a mandatory minimum sentence.
• Assault: Fourth-degree assault (recklessly causing physical injury) is a Class A misdemeanor under AS 11.41.230. First-degree assault (causing serious physical injury with a dangerous instrument) is a Class B felony under AS 11.41.200.
• Theft: Theft of property valued at less than $750 is a Class A misdemeanor under AS 11.46.150. Theft of property valued at $25,000 or more is a Class B felony under AS 11.46.130.
• Minor in possession of alcohol: Classified as a Class B misdemeanor under AS 04.16.050.
• Parking and traffic infractions: Handled under Title 28 as civil infractions with monetary penalties only.

The contrast between a Class B misdemeanor and a Class C felony is operationally significant: the felony classification triggers collateral consequences including loss of voting rights during incarceration, firearm possession restrictions under AS 11.61.200, and professional licensing impacts — none of which attach to misdemeanor convictions.

Decision boundaries

Classification boundaries in Alaska criminal law turn on three primary variables: the type of conduct, the value of harm or property involved, and whether aggravating circumstances apply under AS 12.55.155.

The regulatory context for Alaska's legal system situates these classifications within the broader framework of constitutional requirements and prosecutorial standards. The broader Alaska Legal Services Authority reference structure provides access to adjacent areas including civil procedure, family law, and administrative hearings.

Prosecutors exercise charging discretion within statutory ranges, meaning a charged classification is not always the ceiling. Plea agreements routinely resolve felony charges to misdemeanor pleas, altering sentencing exposure substantially. Courts cannot impose a felony sentence on a misdemeanor conviction regardless of conduct severity — the statutory classification controls.

Offense-specific statutes throughout Title 11 define elements; absent proof of each element beyond reasonable doubt, conviction is not permissible regardless of the classification charged. This element-based structure is the foundational boundary between criminal and non-criminal liability in Alaska state law.
