The law has rules that say when you can be excused for doing something wrong. These rules are from the common law and they still apply to charges under this Act or other laws, unless this Act or another law says something different.

If you are charged with something, the things talked about in this part of the law can be used as a justification or excuse, if they apply to your situation. This means you might not be in trouble if you can show that one of these justifications or excuses applies to what you did.

The law is saying that these justifications or excuses are valid for all charges that they apply to, so you can use them to defend yourself if you are charged with something. You can look at the Compare section to see how this law relates to other laws, like the 1908 No 32 s 40 law.
