Officially Induced Error
A valid excuse for violating the law is on the basis of an officially induced error of law.  The defence arises where the accused is given advice in error that the accused relies upon in doing the criminal act.
Officially induced error is available as a defence to prevent morally blameless individuals, who believe they are acting in a lawful manner, from being convicted.
This is an exception to the principle that ignorance of the law is no excuse.
This defence cannot be invoked for bad advice from court-house duty counsel as legal aid is not part of the government.
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 elements that must be proven are:
- 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.
