Ms Moyagh Murdock:

We recognise this is a complex topic. We are mirroring the process involved in mandatory alcohol testing and random roadside checks. We are aware of the challenges that were raised in previous court cases and some of the provisions in the Bill are aimed at addressing ambiguities and loopholes. However, we have learned lessons in this regard and as a result we are taking a simpler approach. Rather than attempt to list the entire gamut of proscribed drugs, we recognise that drug combinations, trace drugs and prescribed drugs might also be involved. In addition to enforcement, the Bill also aims to deter people from taking the risk of driving while under the influence of drugs. I still expect some challenges to be brought but we will work to ensure the legislation and associated regulations are as straightforward as possible. Given that drug driving is becoming more prevalent, it would be wrong to decide against introducing the legislation out of fear it will be challenged. We will learn from our mistakes and fix loopholes when they arise but under our Constitution people have the right to challenge a charge made against them. We believe the methodology underpinning the legislation is sufficiently robust to support the majority of court challenges and we will be ready to deal with them when they arise.
