Wondering how to successfully fight a DUI charge in Ontario? You're not alone. One of the key elements in many DUI cases is the breathalyzer test, also known as the "Over 80" test in Ontario. In this simplified guide, we'll walk you through how to challenge DUI breathalyzer results and the reasons why your DUI case could be dropped.

What is the Over 80 DUI Charge in Ontario?

If you're facing an "Over 80" DUI charge in Ontario, it means you've been tested and found to have more than 80 milligrams of alcohol per 100 millilitres of blood. The prosecutors, commonly known as crown lawyers, will try to use these breathalyzer readings to prove you're guilty of DUI.

How to Challenge the Integrity of DUI Breathalyzer Results

Challenging the validity of your breathalyzer test is a common defence strategy used by DUI lawyers. Here's how it can be done:

1. Was the Observation Period Properly Followed?

Before you blow into the breathalyzer, the technician needs to observe you for a certain period. They're making sure you aren't eating, drinking, or belching—any of which could skew the results. If they fail to properly monitor you, the breathalyzer test results could be thrown out, weakening the crown's case against you.

2. Was There a Technician Error?

People aren't perfect, and that includes breathalyzer technicians. If the technician made errors while setting up, calibrating, or taking breath samples, those mistakes could invalidate your test results. If this happens, there's a good chance your DUI case could be dismissed.

3. Were Your Rights Violated?

In Ontario, you have the right to consult with a lawyer upon arrest, thanks to the Charter of Rights and Freedoms. If, for instance, the police eavesdrop on your lawyer consultation, your rights are violated. This breach could lead to your case being withdrawn, even if your DUI breathalyzer results were otherwise valid.

4. Were There Legitimate Grounds for Your Arrest?

According to the Charter, police must have a valid reason to believe you were driving under the influence. Simply smelling alcohol or seeing red eyes isn't enough. If the police can't prove they had a good reason to arrest you, your breathalyzer results may not be considered valid evidence.

Summary: How to Win Your DUI Case by Challenging the Breathalyzer

Challenging the DUI breathalyzer test in Ontario can be an effective way to fight an "Over 80" charge. Whether the issue lies with the observation period, technician errors, violations of your rights, or the legitimacy of your arrest, any one of these factors could weaken the crown's case against you. Remember, consult a legal expert for personalized advice on how to best handle your DUI case.
