When the police collect evidence like a breathalyzer test, there are rules that they must follow.
Breathalyzer tests have to be done properly and legally. Where evidence has been “improperly collected” in a criminal matter it may provide a defence for the accused.
If the police are going to use the results of a breathalyzer test to prove an impaired driving care & control charge, the tests have to be:
- taken within time limits,
- by a qualified breathalyzer technician,
- usually within two (2) hours of the time of the offence,
- properly served notice on the accused
- properly reported to the court.
When the case comes to trial, either the breathalyzer technician has to come to court, or the arresting officer to prove that the breathalyzer readings and notice were properly served on the accused.
When it comes to breathalyzer tests the police have time limits, rules and procedures that must be followed. Where the police have have made errors or improperly conducted a breathalyzer test the charges can be dismissed.
If there is a mistake or your rights have been violated, the proper thing for the judge to do is to dismiss or “stay” your charge.
