Do you have a Defence of Honest and Reasonable Mistake of Fact?? Mar 6, 2017 12:00:00 AM ![driving.jpg](https://blog.eastcoastlaw.com.au/hubfs/Family%20Law/driving.jpg) Since the introduction of roadside drug testing, there has been much controversy and public outcry. ** There are two types of offences being:** 1. Use or attempted use of under the influence of alcohol or any other drug 2. Drive a motor vehicle with the presence of a prescribed illicit substance. The road side test, test for the three most common classes of drugs being, Ecstasy, methylamphetamine, and cannabis. With the offence of “drive with the presence of prescribed illicit drug”, there is no obligation for the Police or Prosecution to prove that the defendant was in actual fact under the influence of the drug at the relevant time.  The mere fact that the drug was present in your system in enough to prosecute the charge. However, this brings to question when a driver is “safe” to drive, having previously taken a drug days, or in the case of Cannabis, weeks before.  A driver, after taking a drug, may feel absolutely no further effect of the drug and reasonably believe that they are fine to drive. Or alternatively a person’s drink may have been spiked, or they may have unintentionally passively inhaled a drug at a party, and as such have no knowledge that there is traces of a drug in their system. If this is the case, there may be a defence of “Honest and reasonable mistake of fact” to the offence.   If this defence is to be relied upon, the Defendant must raise some evidence that goes towards a mistake of fact.  But once the Defendant raises this evidence, it is up to the prosecution to prove beyond a reasonable doubt that no such mistake of fact was reasonably and honestly held by the Defendant. This defence was recently used and successfully argued in a matter in Lismore Local Court whereby the Defendant was charged with driving with the presence of cannabis in his system. However, the Defendant argued that he was under the mistaken belief that he was fine to drive as he had previously been told by a Police Office that Cannabis would be out of your system within a couple of weeks. The defendant relied on this information. Ultimately the Magistrate dismissed the charge and found that the Defendant did honestly and reasonably believed that he would be ok to drive and the drug would be out of his system.
