The defendant was charged with assaulting her six-month-old son on December 3, 2017, in Beamsville, Ontario.
The Crown's case relied entirely on statements made by the defendant to police during interviews in December 2017 and March 2018.
The defendant was subjected to a polygraph examination followed by an extended interrogation using techniques consistent with the Reid Technique.
The court found that the defendant's statements were inadmissible both under the common law confessions rule and as a violation of section 10(b) of the Canadian Charter of Rights and Freedoms.
The charge was dismissed.
