The purpose of the defence is to prevent injustices where the “state approving conduct with one hand and seeking to bring criminal sanction for that conduct with the other”
The defence arises in part out of the overly complex nature of regulation. 
A successful application will result in a stay of proceedings.

- The error was one of law or mixed law and fact
- The accused considered the legal consequences of her actions
- The advice obtained came from an appropriate official
- The advice was reasonable in the circumstances
- The advice obtained must be erroneous
- The accused must demonstrate reliance on the official advice
Each element must be proven on a balance of probabilities by the accused.
