Facing criminal charges is a daunting experience, but the legal system allows defendants the chance to present a defence. Whether someone is accused of theft, assault, or a more serious crime, having a solid legal strategy can make all the difference. But what exactly are the most common defences used in criminal cases? Here’s a breakdown of the key arguments lawyers use to challenge charges and protect their clients.
1. Innocence – “I Didn’t Do It”
The simplest and most straightforward defence is claiming innocence. If someone is falsely accused, their criminal defence lawyer Oakville will focus on proving that they were not involved in the crime. This might involve presenting alibi evidence, surveillance footage, witness testimony, or forensic analysis that contradicts the prosecution’s claims.
2. Lack of Evidence – “You Haven’t Proven Your Case”
In any criminal case, the prosecution must prove guilt beyond a reasonable doubt. If there isn’t enough solid evidence to support the charges, the defence can argue that the case should be dismissed. Lawyers may challenge the credibility of witnesses, question the reliability of forensic evidence, or highlight gaps in the prosecution’s argument.
3. Self-Defence – “I Had to Protect Myself”
Self-defence is commonly used in cases involving violent crimes like assault or even homicide. The key argument is that the accused only used force to protect themselves or others from imminent harm. However, for this defence to succeed, the response must be proportional to the threat faced. Excessive or unnecessary force could weaken the argument.
4. Defence of Others – “I Was Protecting Someone Else”
Similar to self-defence, this argument applies when the accused took action to protect another person from harm. The same principles apply—the force used must be necessary and reasonable under the circumstances. This defence is often seen in cases where someone intervenes in a physical altercation or prevents an attack on another individual.
5. Defence of Property – “I Was Protecting My Home or Belongings”
In some situations, people are legally allowed to use force to defend their property. This defence is often used in cases of trespassing or burglary, where the accused claims they acted to prevent unlawful intrusion. However, just like self-defence, the level of force used must be proportionate to the threat.
6. Mistaken Identity – “You’ve Got the Wrong Person”
A mistaken identity defence is used when the accused argues that they have been wrongly identified as the perpetrator. This is particularly relevant in cases based on witness testimony, which can be unreliable. Lawyers may use DNA evidence, surveillance footage, or alibi witnesses to prove their client wasn’t at the scene of the crime.
7. Duress – “I Was Forced to Commit the Crime”
Duress occurs when someone is threatened or coerced into committing a crime against their will. If the accused can prove they acted under extreme pressure—such as a threat to their life or their family’s safety—their legal responsibility may be reduced or even eliminated. However, this defence is rarely successful in cases involving serious violent crimes like murder.
8. Entrapment – “I Was Set Up by Law Enforcement”
Entrapment is used when the accused argues that they only committed the crime because they were pressured or induced by law enforcement. This defence often comes up in cases involving drug offences or undercover operations. However, for entrapment to be valid, the defence must prove that the accused would not have committed the crime without the police’s involvement.
9. Insanity – “I Was Not in My Right Mind”
The insanity defence applies when the accused was not mentally capable of understanding their actions at the time of the crime. This defence is based on medical evidence, such as psychiatric evaluations and expert testimony. If successful, the accused may be committed to a mental health facility instead of prison. However, proving insanity is extremely difficult and requires substantial evidence.
10. Involuntary Intoxication – “I Didn’t Know What I Was Doing”
While voluntary intoxication is rarely a defence, involuntary intoxication can be used in certain cases. If the accused was drugged or unknowingly consumed a substance that impaired their judgment, they might argue that they weren’t in control of their actions. This defence is rare but can apply in cases where someone is unknowingly given drugs or alcohol and then commits an offence.
How These Defences Work in Court
Each of these defences requires strong evidence and a strategic legal approach. Lawyers must not only argue the case effectively but also anticipate and counter the prosecution’s challenges. In some cases, multiple defences might be combined to strengthen the accused’s position.
The Importance of Legal Representation
Regardless of the circumstances, having an experienced criminal defence lawyer is essential. A strong legal team can examine the details of the case, gather evidence, and build the most effective argument. Every case is different, and the right defence strategy can mean the difference between conviction and acquittal.

The right legal defence can make all the difference in securing justice.
