Offence Specific Defences
Self Defence or Defence of Another
An individual has the right to use force to protect themselves if necessary. If person B assaults or attempts to assault person A, person A is legally entitled to use force (i.e., commit an assault) against person B in self defence. Person B cannot use any more force than is necessary to stop person A’s assault. An individual may also use the force necessary to defend an attack on another person. This legal defence is outlined in section 34(1) of the Criminal Code.
Defence of Property
An individual has the right to use force to protect their property or to remove someone from their property. The force used must be reasonable and only what is necessary to expel the person from the property. If a person does not have a legal right to the property, they may not use force to remove another person. This legal defence is outlined in section 35(1) of the Criminal Code.
Person A loses balance while walking down a flight of stairs and in an attempt to regain balance, reaches out and hits person B with their bag. Person A did not intend to hit Person B with the bag, instead their reflex action when falling caused them to make contact with person B.
An assault occurs when the recipient of physical force does not consent to the physical force. If the person being touched does consent to the touch, an assault has not occurred. It is important to note a person cannot consent to bodily harm.
An accused charged with assault with a weapon may argue that they did not have a weapon at the time of the alleged incident. The Crown must prove beyond a reasonable doubt that the accused had a weapon at the time of the alleged incident for there to be a conviction. If the accused establishes this, they could still be charged and convicted with simple assault, however.
