OTTAWA - A judge threw out breath samples that showed Dr. Christy Natsis had more than double the legal limit of alcohol in her blood after a fatal crash, ruling Monday that an OPP officer violated her right to counsel.

Judge Neil Kozloff found that Const. Ryan Besner made "deliberate, systematic and unwarranted" interruptions -- six in all -- before cutting off the Pembroke dentist's call to a lawyer.

That was the "death blow" to any reasonable opportunity to consult a lawyer, Kozloff said.

Natsis, 48, has pleaded not guilty to impaired driving causing death, dangerous driving and having over 80 mg of alcohol in her bloodstream in the head-on crash on Hwy. 17 that killed Bryan Casey almost two years ago.
