A Nelson resident is suing a Nelson Police Department officer and the provincial government following an unusual traffic incident in December.

Sarah Cogswell was arrested for impaired driving and her car was impounded while she was a passenger in a car driven by her adult son, Tiernan Cogswell.

According to a notice of claim filed in B.C. Supreme Court in Vancouver on March 6, Const. Alain Therrien stopped the vehicle in a roadblock on Dec. 13. Tiernan Cogswell passed a blood alcohol test administered by Therrien.

By prior arrangement with his mother, Tiernan was giving her and her husband a ride home from a party at which the pair had been drinking.

Therrien was working as a part of the West Kootenay Integrated Safety Unit, which is a collaboration, run by the province of B.C., between the RCMP and municipal police forces to provide traffic enforcement.

The narrative outlined in this article is based on Cogswell’s notice of claim. Neither Therrien nor the province have yet filed a response.

Tiernan Cogswell’s driver’s licence was a Class 7 learner’s licence, which required him to be supervised by a person over 25 with a full licence sitting in the front passenger seat. That’s where his mother was seated when Therrien stopped them.

Therrien conducted a blood alcohol test on Sarah Cogswell, which she failed.

The court documents allege that Therrien then repeatedly admonished her for transporting her son when she was under the influence of alcohol, calling her a “bad mother” and saying, “It is a good thing [she] didn’t kill anyone tonight.”

He held her for 45 minutes in his car, arrested her for impaired driving, imposed a 90-day driving prohibition and impounded her car, the notice of claim says.

The B.C. Motor Vehicle Act does not specify that the supervisor of a learning driver must be sober.

On Dec. 20, Sarah Cogswell requested a formal review of the incident, but before the review was held, the driving suspension was lifted and the vehicle returned.

Cogswell’s lawsuit asks for $30,000 in damages for physical and mental pain and suffering, wrongful arrest and detainment, lost income, and violation of a number of her Charter rights including the right to liberty and security of the person.

The legal basis of the case is that Sarah Cogswell had not committed an offence and that Therrien had no reason to believe she had, that Therrien did not meet accepted standards of police conduct, and that his comments about her gender and family status were discriminatory and an aggravating factor.

An earlier version of this story mistakenly stated that Therrien was an RCMP officer. He is a member of the Nelson Police Department.
