1 Defences

2 Alibi An alibi is proof that the accused could not have committed the actus reus as they were not near the crime scene. Some alibis are better than others Example: Your wife/husband may not be a credible alibi

3 Mental State Defences Automatism This refers to a condition in which a person acts without being aware of what they are doing. There are 2 types 1. Insane Automatism: a person is not criminally responsible due to a mental disorder

4 A mental disorder is defined as a disease of the mind. It is used after it is shown the defendant committed the guilty act but is not criminally responsible due to a mental disorder. The defence must show one of the following.

5 1. The disorder left the accused incapable of appreciating the nature and quality of their actions. 2. The disorder made them incapable of knowing the act or omission was wrong

6 2. Non-Insane Automatism : This is caused by an external factor like a concussion, medication or sleepwalking. Example: Mr. O’Reilly suffers a stroke at school. He becomes violent and assaults 2 students.

7 Parasomnia or Sexomnia Parasomnia is an unusual behavior, which includes, talking, walking, eating, driving or sexual behavior during sleep. http://topnews.co.uk/26126-recent-study-reveals-sexomnia-more-prevalent-previously-thought http://www.wayodd.com/sexomnia-defense-gets-man-acquittal-on-sexual-assault-charges/v/1426/

8 If someone is found not criminally responsible they may receive: 1. A term in a psychiatric hospital 2. An absolute discharge 3. A conditional discharge

12 Mistake of Law Ignorance of the law is not a defence but a justifiable mistake of law can be. Example: Your tax attorney gives you incorrect information which causes you to break the law

13 Mistake of Fact An honest mistake can be used as a defence. Example: You walk off with someone else's purse, knapsack or cell phone because it is the exact same as yours.

14 Double Jeopardy A person cannot be tried or punished twice for the same offence.

15 Justifications Self-Defence A person may use force to defend against an unprovoked assault They may only use the amount of force (reasonable) necessary to defend against the attack

16 Duress/Compulsion A defence in which the accused is forced by threats to commit a criminal act against their will The threatener must be physically present when the offence is committed

17 The treat has to be immediate Duress is not a defence for violent crimes such as murder, sexual assault, robbery

18 Consent Used when the victim of a crime supposedly gave consent for the criminal act Example: Hockey player charged with assault

19 Entrapment A police action that encourages or aids a person commit an offence Not really a defence but rather an abuse by police that will have the charge quashed
