Legislative Updates in Tennessee Criminal Law

Tennessee’s criminal laws have changed substantially in recent sessions — and many of the changes make outcomes harsher, restrict release, and add conditions that begin the moment of arrest. If you are facing a charge, the law that applies to your case may not be the law you remember. Below is an overview of the developments that most often affect our clients, from the team at Brooks Law Firm in Memphis.

Domestic Assault and Mandatory GPS Monitoring

The most significant recent change in this area is the Debbie and Marie Domestic Violence Protection Act, effective July 1, 2024. Named for Debbie Sisco and Marie Varsos, who were killed by a man released on bail after a prior strangulation and firearm incident, the Act expanded the use of pretrial GPS monitoring in domestic violence cases — and it was described as the first law of its kind in the country.

What it does, in practice:

  • GPS monitoring as a condition of bail for defendants arrested for qualifying offenses — including stalking, aggravated stalking, and especially aggravated stalking; criminal offenses against a domestic abuse victim, sexual assault victim, or stalking victim; and violations of an order of protection.
  • “Shall” versus “may” — and why it matters. The statute directs that the court shall order a monitoring device for felony-level domestic assault defendants, while it may do so for misdemeanor domestic assault defendants. That single word is where much of the defense work happens.
  • Victim notification. The defendant is generally required to pay for the device and for the alleged victim’s access to an app or receptor that alerts them if the defendant enters an exclusion zone or comes into proximity.
  • The defendant bears the cost. A separate electronic monitoring indigency fee also applies in certain aggravated assault convictions involving a domestic abuse victim.

There is a presumption in favor of monitoring in qualifying cases, and avoiding it generally requires an affirmative showing that the defendant is not a danger to the alleged victim or the community. That showing happens before release, which means the defense has to be working from the moment bond is set — not at arraignment.

Related conditions still apply as well: a mandatory hold period after a domestic assault arrest (commonly 12 hours, and potentially longer if a judge finds a continuing threat), no-contact orders, and immediate firearm restrictions. Lawmakers have also continued to push proposals that would expand GPS monitoring as a bail condition into a broader range of cases — so this area remains in motion.

Truth in Sentencing: How Much Time Is Actually Served

Tennessee’s Truth in Sentencing Act, applying to offenses committed on or after July 1, 2022, dramatically changed how much of a sentence a person actually serves. It sharply limited sentence-reduction credits and, for a set of offenses, eliminated early release altogether. For anyone weighing a plea, this is often the single most important thing to understand: the number of years in the plea offer is no longer the whole story — the percentage is.

The 100% Offenses (No Release Eligibility)

For offenses committed on or after July 1, 2022, these must generally be served at 100%, undiminished by sentence credits:

  • Attempted first degree murder
  • Second degree murder
  • Vehicular homicide resulting from the driver’s intoxication
  • Aggravated vehicular homicide
  • Especially aggravated kidnapping
  • Especially aggravated robbery
  • Especially aggravated burglary
  • Carjacking

The 85% Offenses

These require service of at least 85% before release eligibility, with credits limited:

  • Aggravated assault involving a deadly weapon, strangulation or attempted strangulation, or resulting in serious bodily injury or death — including aggravated assault against a first responder or nurse
  • Voluntary manslaughter and reckless homicide
  • Vehicular homicide (other than from intoxication)
  • Aggravated kidnapping
  • Aggravated robbery
  • Aggravated burglary
  • Aggravated arson
  • Involuntary labor servitude and trafficking persons for forced labor or services
  • Employing or possessing a firearm during the commission of a dangerous felony
  • Manufacture, delivery, or sale of a controlled substance as a Class A, B, or C felony with two or more prior such convictions

Standard Release Eligibility (Everything Else)

Offenses outside those lists still follow Tennessee’s standard offender ranges, where release eligibility is calculated as a percentage of the sentence imposed:

  • Range I (standard offender) — 30%
  • Range II (multiple offender) — 35%
  • Range III (persistent offender) — 45%
  • Career offender — 60%

For misdemeanors, the court sets the percentage of the sentence to be served before eligibility for work release or other programs — commonly up to 75%. DUI carries its own mandatory minimum service requirements that must be served day-for-day.

Because a person’s range depends on prior convictions, and because the offense charged determines which percentage applies, the classification fight and the range fight are often worth more to a client than the number of years.

Burglary and Aggravated Burglary

Tennessee reorganized its burglary statutes, and aggravated burglary is now codified within the reorganized burglary provisions (Tenn. Code § 39-13-1003). The practical takeaway for defendants is the sentencing consequence: aggravated burglary now falls within the 85% service category, and especially aggravated burglary is a 100% offense under Truth in Sentencing.

That makes the distinction between simple burglary, aggravated burglary, and especially aggravated burglary enormously consequential. The difference often turns on whether the structure was a habitation and whether serious bodily injury occurred — facts that are contestable, and worth contesting hard.

DUI: Testing, Warrants, and Consequences

DUI enforcement in Tennessee continues to tighten, and the law around chemical testing is where most cases are won or lost. Under Tennessee’s implied consent framework, a breath or blood test may be required based on implied consent, a driver’s express consent, a search warrant, a lawful DUI arrest, or an officer’s probable cause in specific circumstances — including where the driver is alleged to have caused an accident while impaired, was driving impaired with a minor under 16 in the vehicle, or has a prior DUI conviction.

Key points for anyone facing a DUI:

  • Refusal has its own penalty. An implied consent violation carries license consequences separate from the DUI itself.
  • Warrants and blood draws are a frequent and fertile area for suppression motions. How the sample was obtained matters enormously.
  • Penalties escalate sharply with each prior offense, and mandatory minimum jail time must be served.
  • DUI is not expungeable in Tennessee, and it is not eligible for judicial diversion — which is precisely why fighting the charge, or securing a reduction, carries such long-term value.

What These Changes Mean for Your Case

Taken together, the trend is clear: earlier restrictions, longer actual time served, and fewer second chances. That raises the value of everything that happens early in a case — the bond hearing, the charging decision, the classification of the offense, and the negotiation over what a plea is actually to.

It also means old assumptions are dangerous. A sentence that once meant a fraction of time served may now mean nearly all of it. A domestic assault arrest that once meant a bond and a court date may now mean an ankle monitor you pay for. Knowing the current law is not a technicality — it is the difference between a plan that works and one that fails.
