Both alcohol and drug-related 24-hour suspensions are issued under different parts of Section 215 of the Motor Vehicle Act.
While drivers allegedly impaired by alcohol have the right to a review, drivers suspended for drug use either have to convince the ticketing officer to reconsider or file a petition in B.C. Supreme Court for a judicial review.
It's an issue flagged by the director of Simon Fraser University's School of Criminology, Neil Boyd, in a recent report on the enforcement of marijuana-related offences in B.C.
"You shouldn't be driving under the influence of either drug," Boyd said.
"But I don't know why we would treat people who drive under the influence of alcohol somewhat more leniently in this context than people who drive under the influence of cannabis."
Vancouver lawyer Kyla Lee, who specializes in drinking-driving related cases, says the lack of a formal review process places an undue burden on people accused of driving while impaired by drugs.
"It does seem like people are being treated differently, and certainly it raises concerns for me about access to justice and about people's ability actually to challenge these prohibitions," Lee said.
"Not every prohibition is validly or justly issued, and there's a danger here that innocent people are being issued these prohibitions that have more consequences than just removal from the road for 24 hours."
In 2012, the Superintendent of Motor Vehicles issued 7,326 24-hour suspensions for alcohol and 3,800 suspensions for drugs. Of the alcohol-related cases, 172 drivers appealed and the Superintendent revoked 33 suspensions.
Lee says the impact of a roadside suspension can last a lot longer than 24 hours. The penalty can be used as the basis for a longer driving prohibition, and the fact of the suspension becomes part of a driver's record.
"It will say '24-hour prohibition' and then there will be a dash and then it will say the reason for it: alcohol or drugs," she said.
"I think the public is largely uninformed... about the significance of the consequences that can result from one of these on your driving record."
A number of people have gone to B.C. Supreme Court to quash their prohibitions, including a Victoria teen who filed a petition last month against a police officer who handed him a suspension at a roadblock. The teen claims his two passengers admitted to smoking marijuana while he abstained.
A driver in a Vancouver case — Trevor Maxwell Jeanes-McBean — successfully overturned his suspension in similar circumstances last February when the Superintendent declined to appear at the court hearing.
Justice Mark McEwan commented on the lack of a review process in a strongly-worded judgment this summer.
"I reject the (police officer's) submission that there is no recourse to the exercise of the summary power granted under s.215(3) of the Motor Vehicle Act, whether or not the long term consequences for a person's permanent driving record is unfair," McEwan wrote. "That is simply not so."
Reviews of alcohol-related suspension largely focus on questions surrounding the application of screening devices. But drug-related suspensions rely on a police officer's opinion and expertise in assessing signs of impairment.
Boyd says a number of the people he interviewed felt they were wrongly suspended after trying to do the right thing.
"They had been designated drivers for the evening. Sure, the friends in the back smelled of cannabis and the car smelled of cannabis, but they were going to a party and they agreed that they would not consume. Just as people often do with alcohol," he said.
"To the extent that that's an honest statement, it should be respected. Or it should be at least appealable."
The time frame for introducing a more formal review process has not yet been determined.
