How to Challenge Evidence in a Drug Crime Case in North Carolina

Facing drug crime charges in North Carolina can be overwhelming, but an effective legal strategy often involves challenging the evidence presented by the prosecution. The burden of proof lies with the state, and if key pieces of evidence can be questioned or excluded, the chances of a favorable outcome increase significantly. 

There are various ways to challenge evidence in a drug crime case, from constitutional violations to forensic flaws. Many drug crime cases rely heavily on evidence gathered by law enforcement, including physical substances, witness statements, and forensic analysis. However, not all evidence presented by the prosecution is admissible or reliable. 

Mistakes in law enforcement procedures, violations of constitutional rights, and forensic inaccuracies can all provide opportunities for a strong defense. Understanding how to scrutinize and challenge the prosecution's case can make a significant difference in the outcome of a drug-related charge.

Here, you’ll discover how Rodrick A. Rouse, Attorney at Law helps clients challenge evidence in drug crime cases in Greensboro, North Carolina, including the legality of search and seizure, the chain of custody, forensic analysis, and more.

Challenging the Legality of the Search and Seizure

One of the most effective ways to challenge evidence in a drug case is by arguing that law enforcement violated the Fourth Amendment, which protects individuals from unreasonable searches and seizures, according to Constitution Annotated.

Searches and seizures are allowed in investigations when there’s permission from the person or place being searched, probable causes that the person or place being searched has evidence of a crime or a warrant.

One key way to challenge the evidence in a drug crime case is to challenge the legality of the search and seizure where the evidence was obtained. Search and seizure evidence can be challenged in the following ways:

Lack of a Warrant or Probable Cause

In North Carolina, police must typically have a valid search warrant or probable cause to conduct a search. If officers obtained evidence without either, the defense can file a motion to suppress, which can lead to the exclusion of the evidence in court.

Illegal Traffic Stops

If drugs were discovered during a traffic stop, the defense can argue that the stop itself was unlawful. Police must have reasonable suspicion that a crime or traffic violation occurred to pull someone over. If the stop was unwarranted, any evidence found during the search could be deemed inadmissible.

Unlawful Consent Searches

Sometimes, officers rely on consent to conduct a search. However, if consent was obtained through coercion or intimidation, it may not be legally valid. A skilled attorney can challenge whether the defendant truly gave voluntary consent.

Questioning the Chain of Custody

Secondly, the prosecution must establish a clear chain of custody for the drugs in question. This means tracking every step, from seizure to presentation in court. If the chain of custody is broken, it can create doubt about the integrity of the evidence.

The chain of custody can be challenged in the following ways:

Mishandling or Tampering of Evidence

Evidence must be properly documented and stored. If there’s any indication that the drugs were misplaced, altered, or contaminated, the defense can argue that the evidence is unreliable and should be dismissed.

Gaps in Documentation

Incomplete records of who handled the drugs and when can be a basis for exclusion. Defense attorneys often scrutinize police reports and lab records to identify inconsistencies.

If it can be proven that the evidence was mishandled or there are gaps in documentation, your defense lawyer can create doubt about the integrity of the evidence. If you’re facing a drug crime in North Carolina, Rodrick A. Rouse may use this method to strengthen your defense.

Challenging the Forensic Analysis

Additionally, forensic errors can be another avenue for challenging drug evidence. Lab tests are crucial in proving that a substance is illegal, but forensic testing is not always foolproof.

Inaccurate Lab Results

Crime labs can make mistakes, whether due to human error, equipment malfunctions, or contamination. A defense attorney can request independent testing to verify the prosecution’s claims.

Questionable Expert Testimony

The credibility of forensic experts can be challenged by scrutinizing their qualifications, testing procedures, and prior cases. If an expert witness lacks proper credentials or has a history of inaccurate analyses, their testimony may be discredited.

Arguing Entrapment

Another way to challenge evidence in a drug crime case is by arguing entrapment. Entrapment occurs when law enforcement induces a person to commit a crime they otherwise would not have committed. This defense is based on the principle that the government shouldn’t manufacture crime but instead detect and prevent criminal activity.

To successfully argue entrapment, the defendant must demonstrate that they were not predisposed to commit the drug-related offense and that law enforcement used coercion, deception, or undue persuasion to encourage their participation. 

This can include tactics such as repeated requests, intimidation, fraudulent assurances, or exploiting a defendant’s vulnerabilities, such as financial hardship or addiction.

If the defendant can prove entrapment, the charges may be dismissed, as courts aim to prevent law enforcement from overstepping ethical and legal boundaries in securing drug crime convictions.

Disputing Possession

In drug cases, the prosecution must prove that the defendant had possession of the controlled substance. There are two types of possession: actual and constructive.

Lack of Actual Possession

If the drugs were not found on the defendant’s person, the prosecution must prove constructive possession—that the defendant had control over the drugs. If multiple people were present where the drugs were found, the defense can argue that the drugs did not belong to the defendant.

Proving Lack of Knowledge

A defendant may claim that they were unaware of the drugs’ presence. For example, if drugs were found in a shared vehicle or residence, the defense can argue that another person was responsible.

Challenging Witness Testimony

Furthermore, witness testimony, including that of confidential informants, is often a key part of drug crime prosecutions. However, such testimony can be unreliable.

Bias and Motives

Informants often have incentives to provide testimony, such as reduced sentences or financial rewards. A defense attorney can question their credibility by highlighting their motives.

Contradictory Statements

If witnesses provide inconsistent accounts or change their testimony over time, this can be used to cast doubt on their reliability.

Filing a Motion to Suppress Evidence

If evidence was obtained unlawfully, the defense can file a motion to suppress before trial. A successful motion can prevent the prosecution from using crucial evidence, potentially leading to case dismissal or reduced charges.

Negotiating a Plea Bargain

If challenging evidence weakens the prosecution’s case, it may be possible to negotiate a plea deal for reduced charges or sentencing. This can be an alternative strategy if complete dismissal is unlikely.
