Probable Cause and Preliminary Hearings in Tennessee
Probable cause and preliminary hearings sit at the lowest evidentiary bar in the whole case, and most people misunderstand the hearing in both directions. Winning it does not end the case, and losing it does not mean much either.
Probable Cause Is the Lowest Bar Anyone Has to Clear
A preliminary hearing asks one question: is there probable cause to believe an offense was committed and that this person committed it. Not whether the State can prove it, not whether the evidence is admissible, and not whether anyone is guilty. It is the same standard that supports an arrest, applied by a judge instead of an officer.
That is why probable cause and preliminary hearings disappoint people who expect a trial and get written off by people who treat them as a formality. The hearing decides very little and it reveals a great deal, and those two facts are the whole point of the morning.
The constitutional root is article I, section 7 of the Tennessee Constitution, which secures the people "from unreasonable searches and seizures" and condemns general warrants issued "without evidence of the fact committed." The idea underneath the standard is old and simple. The State has to be able to point at something before it takes hold of a person.
What probable cause requires in practice is facts rather than a hunch, and considerably less than proof. Officer observation, a witness account, physical evidence, or some combination can carry it. A single witness the defense believes is lying can carry it, because credibility at this stage is not weighed the way a jury would weigh it.
The Hearing Is Not Where Suppression Gets Decided
Whether a search was lawful, whether a statement was taken in violation of Miranda, whether evidence comes in at trial, these are admissibility questions. The preliminary hearing decides probable cause. They are different questions, asked at different stages, and a motion to suppress belongs in the trial court after indictment.
The page this one replaces listed illegal search and lack of Miranda warnings among the "common defenses during the preliminary hearing." That sets an expectation the morning cannot meet. A person who walks in expecting his search to be thrown out walks out believing something went wrong, when nothing did.
The connection is real but indirect. What a witness says under oath at the hearing about how a stop began, what was said, and in what order, is exactly the material a suppression motion is later built from. The hearing does not decide the issue. It supplies the record the issue gets decided on.
What the Preliminary Examination Statutes Actually Give You
Chapter 10 of Title 40 is titled Preliminary Examination, and almost nothing written for the public about this hearing mentions it. It contains four provisions worth knowing before you walk in.
| Section | What it provides |
|---|---|
| § 40-10-101 | The magistrate shall immediately inform you of the offense charged and of your right to aid of counsel "in every stage of the proceedings" |
| § 40-10-102 | The magistrate shall allow a reasonable time to send for counsel and "if necessary, shall adjourn the examination for that purpose" |
| § 40-10-103 | The magistrate shall, "on demand of either party, put all witnesses under the rule" On demand |
| § 40-10-104 | The bail amount is endorsed on the commitment and signed, and the sheriff may discharge on sufficient bail |
The third row is the one worth the reading. Putting witnesses under the rule means they are separated and cannot sit in the courtroom listening to each other testify. Section 40-10-103 makes it mandatory on demand rather than discretionary, which matters most in exactly the cases where two accounts have had time to converge.
The second row matters for anyone who arrives at a first appearance without a lawyer and is asked whether they want to go ahead. A reasonable time to send for counsel is not a courtesy, and the statute contemplates adjourning the examination to make it real.
You Can Usually Waive the Hearing, and the State Can Object
Section 40-10-114 provides that the preliminary hearing "may not be waived by the defendant if the state makes a timely objection, for good cause shown." Waiver is the norm and it is often correct, but it is not something the defense decides alone.
Waiving makes sense when a plea is already being negotiated, when the hearing would hand the State a chance to lock in testimony it does not yet have, or when a witness who might not appear later will certainly appear that day. Holding it makes sense when the account is the case and nobody has heard it under oath yet.
That is a real strategic decision with reasons running both directions, and it is made early, usually within days of an arrest, often before anyone has seen much of the file. It is one of the strongest arguments for having a lawyer involved before the first court date rather than after it.
A Dismissal at the Preliminary Hearing Does Not End the Case
If the judge finds no probable cause, the charge is dismissed in General Sessions. The State may still take the same facts to the grand jury, and an indictment starts the case again in the trial court. Article I, section 14 of the Tennessee Constitution says "no person shall be put to answer any criminal charge but by presentment, indictment or impeachment," and the grand jury is its own route to exactly that.
Section 40-13-101 defines an indictment as "an accusation in writing presented by the grand jury of the county charging a person with an indictable offense." The grand jury hears the State. There is no defense case there, no cross-examination and no judge weighing both sides.
The same mechanism runs in the other direction and removes the hearing entirely. A grand jury can indict before any preliminary hearing is held, and when that happens the General Sessions case ends and the defendant answers in the trial court. Nothing has gone wrong. It is simply the most common reason a hearing a client was waiting for vanishes from the docket. Our post on General Sessions versus Criminal Court maps where each stage happens.
So the honest framing is this. The preliminary hearing is not a gate that closes. It is a look at the case, under oath, earlier than you will get one anywhere else, and the value is in what you learn and preserve rather than in the ruling.
Testimony Given Once, Before Anyone Has Smoothed It Out
-
The account gets fixed in place
An officer or a complaining witness answers questions under oath, on the record, close to the events and before months of preparation. Whatever is said becomes the version that any later account has to be reconciled with.
-
Cross-examination, with nothing to lose
The judge is not deciding guilt, so the ordinary risk of a bad answer is much lower than at trial. Questions that would be too dangerous in front of a jury can be asked here, and the answer is useful either way.
-
The suppression motion gets its raw material
Sequence is everything in a stop. When the lights came on, when the question was asked, when consent was requested, when the dog arrived. That timeline is built from testimony, and this is the first chance to get it on a record.
-
You see the shape of the State's case
Which witnesses they lead with, what they do not bother to call, and how much of the file they are willing to show. That is information the defense does not otherwise receive until well after indictment.
Probable Cause and Preliminary Hearings FAQ
What does a judge decide at a preliminary hearing in Tennessee?
Only whether there is probable cause to believe an offense was committed and that the defendant committed it. Guilt is not decided and the standard is far below what a conviction requires.
Can I get evidence suppressed at the preliminary hearing?
The hearing decides probable cause, not admissibility. A motion to suppress belongs in the trial court after indictment. What the hearing does supply is sworn testimony about how the stop or search unfolded, which is often what the later motion is built from.
What happens if the judge finds no probable cause?
The charge is dismissed in General Sessions, but the State may still present the same facts to a grand jury. Section 40-13-101 defines an indictment as an accusation in writing presented by the grand jury, and an indictment starts the case in the trial court.
Can I waive my preliminary hearing?
Usually, but not unilaterally. Section 40-10-114 provides that the hearing may not be waived by the defendant if the state makes a timely objection for good cause shown.
Can I keep the witnesses from hearing each other testify?
Yes, on request. Section 40-10-103 provides that the magistrate shall, on demand of either party, put all witnesses under the rule, meaning they are kept separate and excluded during other testimony.
Why did my preliminary hearing get cancelled?
Most often because the grand jury indicted before the hearing was held. The General Sessions case then ends and the case is answered in the trial court. It is a normal path rather than a sign anything went wrong.
The Decisions Here Get Made Early and Are Hard to Revisit
Austin Tomlinson handles preliminary hearings in Davidson County and across Middle Tennessee, and takes every case himself. Whether to hold the hearing or waive it is decided within days of an arrest, which is why the call is worth making before that date rather than after it.
