Breaking Down Probable Cause and Preliminary Hearings: Your First Line of Defense in Tennessee Criminal Cases

In the criminal justice system, probable cause plays a critical role in determining whether law enforcement can proceed with actions like arrests and searches. In Tennessee, the preliminary hearing is a key step where probable cause is tested before a case moves forward to trial. If you or someone you know is facing criminal charges, understanding both probable cause and the function of the preliminary hearing is essential to building an effective defense.

What is Probable Cause?

Probable cause is a standard required by the Fourth Amendment of the U.S. Constitution and Tennessee law, which states that there must be enough credible evidence to justify an arrest or search. It requires more than mere suspicion but less than the proof needed for a conviction.

Probable cause can be based on a variety of sources, including:

• Witness statements: Reliable eyewitnesses or victims can provide crucial information.
  

• Physical evidence: Tangible items like weapons, drugs, or stolen goods can support probable cause.
  

• Police observations: Law enforcement officers can make arrests based on their observations of illegal activity.
  

However, probable cause must be based on concrete facts, not mere hunches or speculation.

How Probable Cause Influences Arrests and Searches

In Tennessee, law enforcement must demonstrate probable cause when seeking an arrest warrant from a judge. For searches, the same standard applies unless an exception (like consent or exigent circumstances) exists. If police make an arrest or conduct a search without a warrant, they must still be able to justify their actions based on probable cause.

If it turns out that probable cause was lacking, any evidence obtained during the arrest or search could be ruled inadmissible in court under the exclusionary rule. This can lead to the dismissal of charges if that evidence is essential to the prosecution’s case.

What Happens if There’s No Probable Cause?

If probable cause is challenged and found lacking, the following consequences can occur:

• Suppression of evidence: Illegally obtained evidence cannot be used in court.
  

• Case dismissal: If there is no admissible evidence to support the charges, the case could be thrown out.
  

The Preliminary Hearing: Evaluating Probable Cause

The preliminary hearing is one of the first critical phases in the criminal justice process, where a judge determines whether enough evidence exists to justify the charges. This hearing is designed to protect individuals from being prosecuted without sufficient legal grounds.

When Does a Preliminary Hearing Take Place?

In Tennessee, a preliminary hearing usually occurs within a few weeks of the defendant’s initial appearance in court, especially for felony charges. This hearing is held in General Sessions Court, and its primary purpose is to determine whether probable cause exists to believe that a crime was committed and that the defendant was the person who committed it.

The defendant has the right to waive the preliminary hearing, which sometimes happens if both sides are negotiating a plea agreement or if the defense believes that skipping the hearing is strategically beneficial.

What Happens During the Preliminary Hearing?

During the preliminary hearing, the prosecution presents evidence to establish probable cause. This can include:

• Testimony from witnesses: Police officers, victims, or others may testify to support the state’s case.
  

• Documentary or physical evidence: Items like reports, weapons, or drugs may be introduced.
  

The defense has the opportunity to:

• Cross-examine witnesses: Defense attorneys can question the state’s witnesses to challenge their credibility or the strength of their testimony.
  

• Present their own evidence: Although rare at this stage, the defense can introduce evidence or witnesses to dispute probable cause.
  

• Argue for dismissal: If the evidence presented by the prosecution is weak, the defense can argue that there is no probable cause and request that the charges be dismissed.
  

The judge’s role at this stage is not to determine whether the defendant is guilty, but simply whether there is sufficient evidence to justify moving the case forward. This is why the standard of proof is lower than at trial.

Strategies at the Preliminary Hearing

The preliminary hearing is a key opportunity for the defense to:

1. Challenge the State’s Case: If the prosecution’s evidence is flimsy, the defense can expose those weaknesses, potentially leading to the dismissal of charges.
   

2. Gather Information for Trial: Even if the case moves forward, the preliminary hearing can provide insight into the prosecution’s strategy, witnesses, and evidence.
   

3. Set Up Pretrial Motions: Evidence or testimony revealed during the preliminary hearing may be the basis for future pretrial motions, such as motions to suppress evidence.
   

Can the Defense Win at a Preliminary Hearing?

While dismissals at the preliminary hearing are rare, they do happen, especially if the state’s evidence is insufficient or based on unconstitutional actions (like an illegal search). In some cases, the defense can also leverage a weak case to negotiate a favorable plea deal.

The Judge’s Role in the Preliminary Hearing

The judge in the preliminary hearing does not decide whether the defendant is guilty or innocent. Instead, they assess:

1. Whether a crime has likely been committed.
   

2. Whether the defendant is reasonably connected to that crime.
   

If the judge finds probable cause, the case will proceed to the grand jury or trial court. If the judge does not find probable cause, the charges could be dismissed at that stage, although the state may still present the case to a grand jury for possible indictment.

Common Defenses During the Preliminary Hearing

There are several common defenses used at this stage, including:

1. Lack of Probable Cause: Arguing that the state has not presented enough credible evidence to justify the charges.
   

2. Constitutional Violations: Challenging the legality of the arrest or search that led to the charges (e.g., illegal search and seizure, lack of Miranda warnings).
   

3. Credibility of Witnesses: Questioning the reliability or accuracy of witness testimony, especially if based on inconsistent or biased statements.
   

Conclusion

In Tennessee, probable cause and the preliminary hearing serve as essential safeguards in the criminal justice process. While the preliminary hearing is not as formal as a trial, it is a critical moment where a skilled defense attorney can challenge the state’s case, gather crucial information, and begin building a robust defense.
