Types of defenses in criminal law

When you face criminal charges, the defense strategy chosen can seriously impact the outcome of your case.

In criminal law, defenses are critical tools to challenge the prosecution's claims and protect your rights. Depending on the the specifics of your case, your criminal defense lawyer might employ various defenses. Understanding these options can empower you as you navigate through the legal process.

At Genesis DUI & Criminal Defense Lawyers, we know that criminal defenses come in many shapes and forms. Each defense strategy serves a unique purpose, from proving your innocence to highlighting constitutional violations during your arrest. These defenses can range from alibi evidence that you were not at the crime scene to claims of self-defense.

Your attorney's role is to evaluate the evidence, understand the legal nuances, and apply the most effective defense. Learn more about major criminal law defenses below. Then, contact us to schedule a free case consultation.

Importance of Choosing the Right Defense

Selecting the appropriate defense is pivotal in a criminal trial. A well-chosen defense can create reasonable doubt among the jury, potentially leading to an acquittal. It's about proving innocence and strategically challenging the prosecution's evidence.

A solid defense can also limit the potential consequences if a conviction does occur. For instance, by demonstrating mitigating circumstances, your lawyer might reduce the severity of your sentencing.

It is important to work with a skilled criminal defense attorney who can navigate the complex legal system and advocate effectively on your behalf.

How To Choose the Right Criminal Defense Lawyer

How to chooese the right criminal defense lawyer
  • Experience in criminal law. It would help if you had a lawyer who specializes in criminal law. They should have a strong track record of handling cases similar to yours. Experience brings insight into the nuances of the law and familiarity with court procedures.
  • Local court experience. Choosing a lawyer with experience in the court where your case is being heard is beneficial. They are likely familiar with the preferences and tendencies of the judges and prosecutors in that jurisdiction.
  • Client testimonials. Look for a criminal defense lawyer who has been highly recommended by past clients. Positive testimonials can provide insight into the lawyer's ability to handle cases successfully.
  • Communication skills. Your lawyer should communicate clearly and keep you informed throughout your case. They should be accessible to answer your questions and explain complex legal concepts in understandable terms.
  • Analytical skills. A defense attorney can analyze a case from multiple angles to craft the best defense strategy. They should identify weaknesses in the prosecution's case and highlight them in their defense.

Affirmative Defenses

Affirmative defenses involve denying the charges and presenting additional facts that justify the alleged criminal act.

They require proving certain elements that can absolve the defendant of responsibility for the crime. This proactive defense strategy can be very effective if handled correctly.


Self-defense is an affirmative defense used when a person reasonably believes they are in imminent danger of harm. The law allows individuals to protect themselves, even using force.

However, the force used must be proportional to the threat faced.

Defense of Others

Similar to self-defense, the defense of others allows you to act on behalf of another person under threat. This defense applies when you believe another person is in immediate danger and needs protection.

Like self-defense, the response must be reasonable and proportional to the danger presented.

Procedural Defenses

Procedural defenses

Procedural defenses focus on errors in the way law enforcement handled the investigation or prosecution. These errors can sometimes lead to the dismissal of charges if they violate the defendant's rights. Your rights must be respected, even if you have been charged with a crime.

Illegal Search and Seizure

This defense challenges evidence obtained through a search and seizure that violates the Fourth Amendment. If law enforcement searches without a warrant or probable cause, the evidence might be excluded from the trial. We can examine your case to see if your rights were violated.

Violation of Miranda Rights

Your self-incriminating statement may not be admissible in court if you did not read your Miranda rights during your arrest. This defense protects against self-incrimination and ensures that defendants know their rights.

Alibi Defense

An alibi defense is used when you claim to have been elsewhere when the crime occurred. This defense requires solid evidence to confirm your whereabouts during the alleged criminal act.

You need credible witnesses or physical evidence confirming your location to establish an alibi. This could include video footage, transaction records, or eyewitness accounts.

Collecting strong evidence is key to substantiating an alibi. This might involve gathering security camera footage, credit card receipts, or mobile phone location data that can place you away from the crime scene.

Insanity Defense

Insanity defense

The insanity defense is challenging to prove but can be effective if successful. It argues that you were mentally incapable of understanding the nature or wrongfulness of your actions due to a severe mental disorder.

Legal standards for the insanity defense vary by state, but generally, you must demonstrate a serious mental illness or defect at the time of the crime. This often requires expert testimony from mental health professionals.

Proving Insanity in Court

Proving insanity involves demonstrating that mental illness impaired your ability to distinguish right from wrong. This usually requires detailed medical records, expert evaluations, and compelling testimony.

For a criminal defendant to prove insanity in court, we need to partner with experts in the field. This can be one of the more challenging legal defenses to leverage.

Duress and Coercion

Duress and coercion can excuse criminal behavior if you are forced to commit the act under threat of immediate harm. This defense argues that you would not have committed the crime under normal circumstances.

Duress involves scenarios where you act out of fear for your safety or the safety of others. Examples include being forced to commit a crime at gunpoint or under threat of serious harm. We will examine your case to see if duress and coercion may have played a role.

Legal Requirements for Duress

To successfully claim duress, you must show you had no reasonable opportunity to escape or alert authorities. The threat must be immediate and credible, substantially influencing your decision to commit the crime.

Entrapment Defense

Entrapment occurs when a law enforcement officer causes a person to commit a crime they would not have otherwise committed. This defense is based on protecting individuals from overzealous police tactics.

The entrapment defense hinges on proving that law enforcement initiated and persuaded the defendant to commit the crime.

It focuses on the police's conduct rather than the defendant's. We always look closely at how the police handled themselves during the arrest.

How to Prove Entrapment

Proving entrapment involves demonstrating that you were not inclined to commit the crime before the law enforcement's involvement.

Evidence may include communication records or undercover interactions. It can be difficult to prove entrapment, but all options are on the table regarding your defense.

How Your Lawyer Chooses the Right Defense Strategy for Your Case

  • Case review and fact-gathering. Your criminal defense lawyer begins by thoroughly reviewing your case's details. They collect information, speak with witnesses, and review the evidence law enforcement has gathered. This comprehensive review forms the foundation of your defense strategy.
  • Legal analysis. The next step involves a detailed legal analysis of the charges against you. Your lawyer will identify applicable laws and precedents that can influence your case. They assess all legal options to determine the most viable defense under current laws.
  • Expert consultation. Often, cases require insights from professionals outside the legal field, such as forensic analysts, medical experts, or psychologists. Your attorney might consult these experts to bolster your defense with scientific or specialized evidence that supports your case.
  • Assessment of prosecution's case. Developing a defense strategy means understanding and predicting the prosecution's moves. Your lawyer will critically assess the strength of the prosecution's evidence and strategy. Identifying weaknesses or gaps in the prosecution's case can be pivotal.
  • Client collaboration and strategy formation. Finally, your lawyer will collaborate closely to ensure that the chosen defense strategy aligns with your best interests and legal goals. They will review your options and the possible outcomes of each, allowing you to make informed decisions about how to proceed in your defense.
