Ms Angela Denning:

In general, right across the courts, whenever there is a new process or a new piece of legislation, it will be tested. I remember when the Intoxilyzer came in for drink-driving, there were multiple cases related to it. Whenever there is new legislation or a new process, people will test it to see what the words mean and so on. That is the reality we see every day. Every time there is a change, a few cases come out of it.
