The accused was charged with sexual assault and two counts of assault against his wife.
The complainant alleged the offences occurred on New Year's Eve 2017 but did not report them to police until October 2018, during a marital separation and concurrent family court proceedings for sole custody of their child.
The court found the timing and circumstances of the disclosure, along with inconsistencies in the complainant's accounts, provided a powerful motive to fabricate and raised a reasonable doubt.
The accused was found not guilty on all counts.
