Quebec Court Judge Thierry Nadon has tossed out charges against a woman whose driving led to two deaths on the West Island. 

Overzealous police violated Stacey Snider's privacy by listening in on hospital conversations concerning Snider's blood-alcohol level, Nadon ruled.

Stacey Snider was driving on August 14, 2012 when she collided with a bus at 55th and Lindsay in an impact so severe the bus was knocked on its side, killing driver Sylvain Ferland, 49. Janet Stoddard Snider, 61, the driver’s mother, was also killed in the crash.

Police only thought of testing Snider for alcohol after an officer overheard a hospital staffer say that Snider had a high blood alcohol level, which led to the request to take a blood sample.

That sequence of events constituted a violation of Snider’s privacy, Snider’s lawyer Pierre Joyal argued.

"Basically it's the right of everyone who was hospitalized to have his privacy and dignity,” Joyal said Friday. "Anyone who is admitted to a hospital and fighting for his life should never worry about policemen snooping around, getting private medical information."

One of the 14 bus riders expressed disappointment with the ruling.  “I don’t feel justice has been served,” said injury victim Stephany Ezard who attended much of the trial. "She knew what she was doing."
