The defendant was charged with assaulting his wife and causing bodily harm on July 20, 2013.
The incident arose from a dispute over whether the defendant should take their seven-year-old son to a Muay Thai class.
The case turned on credibility and reliability of the complainant and defendant's accounts of the altercation.
The defendant claimed self-defence, asserting that the complainant initiated physical contact by punching him repeatedly in the head and eye while he was kneeling in front of her on the couch, and that he hit her twice to make her stop.
He further claimed that when she later swung a picture frame at him, he pushed her away in self-defence, causing her to fall accidentally.
The complainant's evidence was marked by significant memory gaps, including periods of unconsciousness, and contradictions between her trial testimony and her earlier statement to police.
The court found the defendant's evidence more credible and coherent despite some concerns about his testimony, and acquitted him.
