For self-defence to apply when you are charged with a crime, the following must be the case:

  2. Your response to the threat was reasonable in the circumstances.

How can it be established that I believed my conduct was necessary for self-defence to be applicable?

Defend yourself or another person OR

Prevent or stop your false imprisonment of the false imprisonment of another person OR

Protect property from damage or unlawful taking OR

Prevent or remove a person from trespassing on your land or premises.

What is a reasonable response in the circumstances?

This will be assessed objectively on a case-by-case basis. Conduct will be found to be reasonable if it was proportionate to the threat and not excessive.
