Felony carnal knowledge of a juvenile in Louisiana is sexual intercourse between a person 17 or older and a minor aged 13 through 16 when the age gap is four years or more, and a conviction carries up to 10 years in prison, a fine of up to $5,000, and 25 years on the sex offender registry.1Louisiana State Legislature. Louisiana Revised Statutes Title 14 RS 14:80 – Felony Carnal Knowledge of a Juvenile The consequences reach well past the sentence, including federal firearm restrictions, a marked passport, and, for non-citizens, mandatory removal from the country.
What Counts as the Offense
Louisiana Revised Statutes 14:80 creates two paths to a felony charge. The first, and the one most charges are built on, is a person aged 17 or older having sexual intercourse with someone aged 13 through 16 when the two are at least four years apart in age and are not married to each other.1Louisiana State Legislature. Louisiana Revised Statutes Title 14 RS 14:80 – Felony Carnal Knowledge of a Juvenile “Sexual intercourse” is defined broadly to cover oral, anal, and vaginal intercourse, and penetration of any degree completes the crime.
The second path applies when a person commits a second or subsequent misdemeanor carnal knowledge offense, or when a person already required to register as a sex offender commits even a first misdemeanor offense. In those situations the conduct is prosecuted as a felony rather than a misdemeanor.1Louisiana State Legislature. Louisiana Revised Statutes Title 14 RS 14:80 – Felony Carnal Knowledge of a Juvenile
The statute is written for situations where the minor agreed to the contact. That is what separates this offense from rape and sexual battery, which turn on force or absence of consent. The legislature’s view is that the age gap itself creates a power imbalance the law refuses to recognize, so apparent willingness from the younger person does not take the conduct outside the statute.
Prison Time and Fines
A conviction exposes the defendant to imprisonment for up to 10 years, with or without hard labor, and a fine of up to $5,000.1Louisiana State Legislature. Louisiana Revised Statutes Title 14 RS 14:80 – Felony Carnal Knowledge of a Juvenile The range leaves the sentencing judge wide latitude. Where a given case lands depends on factors like the specific ages, the nature of the relationship, and the defendant’s criminal history.
For many defendants the sentence itself is the smaller problem. A felony record closes off jobs and professional licenses on its own, and because this particular felony triggers sex offender registration, the day-to-day restrictions on housing, employment, and movement last for decades after any prison term ends.
Why Consent and Not Knowing the Age Won’t Help
Two defenses people reach for first are unavailable. The statute states directly that “lack of knowledge of the juvenile’s age shall not be a defense.”1Louisiana State Legislature. Louisiana Revised Statutes Title 14 RS 14:80 – Felony Carnal Knowledge of a Juvenile It does not matter that the minor looked older, showed a fake ID, or lied about their age. If the minor was under 17 and the age gap was four years or more, the offense is complete.
Consent is not a defense either, for the reason given above: the statute was designed for consensual encounters. In practical terms, the only factual defenses available are challenges to whether sexual intercourse actually occurred or whether the ages and the gap are what the state claims.
25 Years on the Sex Offender Registry
Anyone convicted of this offense must register as a sex offender in Louisiana, and because the victim is a minor, the registration period is 25 years.2Louisiana State Legislature. Louisiana Revised Statutes Title 15 RS 15:543.1 – Sex Offender Notification Form The clock starts at release from prison, or at sentencing if no prison time is ordered.
Registration is handled in person at the sheriff’s office in every parish where the offender lives, works, or attends school. The offender provides name and aliases, home address, employer address, school address, and two forms of proof of residence, and must report any changes promptly.3Louisiana State Legislature. Louisiana Revised Statutes Title 15 RS 15:542 – Registration of Sex Offenders and Child Predators
Community Notification
Louisiana’s notification rules reach further than most people assume. The offender must mail written notice to at least one person in every residence and business within a one-mile radius in rural areas, or three-tenths of a mile in urban and suburban areas. Each notice includes the offender’s name, address, physical description, photograph, and the crime of conviction.4Louisiana State Legislature. Louisiana Revised Statutes Title 15 RS 15:543.1 – Sex Offender Notification Form Because the victim was a minor, notice also goes to the superintendent of the local school district and to the superintendent of any nearby park, playground, or recreation district.
The offender must also publish notice in the official parish journal on two separate days. The entire notification process has to happen within 21 days of conviction if the offender is not taken into custody, or within 21 days of release from prison. It repeats with every move, and at least every five years even when nothing changes.
Penalties for Failing to Register
Missing a registration deadline or giving false information is itself a felony. A first offense carries a fine of up to $1,000 and two to ten years of hard labor, with no parole, probation, or suspended sentence. A second offense raises the fine to $3,000 and the prison range to five to twenty years, again with no parole or probation.5Louisiana State Legislature. Louisiana Revised Statutes Title 15 RS 15:542.1.4 – Failure to Register and Notify as a Sex Offender or Child Predator Courts have no discretion to go below those minimums.
Firearm, Immigration, and Passport Consequences
Federal law bars anyone convicted of a crime punishable by more than one year in prison from possessing firearms or ammunition.6Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts A ten-year exposure easily crosses that line, so a conviction triggers a lifetime federal ban, and Louisiana imposes its own firearm prohibition on felons. Violating either ban is itself a new felony.
For non-citizens, the stakes are higher still. Federal immigration law treats “sexual abuse of a minor” as an aggravated felony,7Office of the Law Revision Counsel. 8 USC 1101 – Definitions a classification that brings mandatory removal from the United States, a permanent bar on re-entry, and a permanent bar on establishing the good moral character required for naturalization.8USCIS. Volume 12 Part F Chapter 4 – Permanent Bars to Good Moral Character A plea that looks favorable on the criminal side can be devastating on the immigration side, so a non-citizen facing these charges should talk to an immigration lawyer before accepting any disposition.
Travel is also restricted. A registered offender planning to leave the United States must notify the jurisdiction of residence at least 21 days before departure.9eCFR. 28 CFR Part 72 – Sex Offender Registration and Notification The State Department is required to place a visible identifier on the passport of a covered sex offender in a conspicuous location,10Office of the Law Revision Counsel. 22 USC 212b – Unique Passport Identifiers for Covered Sex Offenders and many countries deny entry to travelers carrying that marking.
How This Differs From the Misdemeanor Version
Louisiana draws a sharp line between the felony and misdemeanor forms. Misdemeanor carnal knowledge of a juvenile, at R.S. 14:80.1, covers the same kind of conduct when the age gap is less than four years. The penalty is a fine of up to $1,000, up to six months in jail, or both. No hard labor, and nothing like the 25-year registration attached to the felony.
The four-year gap is the whole hinge. A 19-year-old with a 16-year-old is a three-year gap and falls under the misdemeanor. A 20-year-old with a 16-year-old crosses into the felony, with up to ten years in prison, a quarter-century on the registry, and the federal consequences on top. One year in the older person’s age can be the difference between six months in parish jail and a decade in state prison.
