Former vice-admiral Haydn Edmundson has been found not guilty of sexual assault and committing an indecent act in a case that dates back to 1991.

Edmundson was head of the military含羞草研究社檚 personnel in 2021 when he was accused of assaulting another member of the navy during a deployment three decades earlier.

The complainant, Stephanie Viau, testified during the trial that she was 19 years old and in the navy含羞草研究社檚 lowest rank at the time of the alleged assault, while Edmundson was an older officer.

Edmundson pleaded not guilty and testified that he never had sexual contact with Viau.

Justice Matthew Webber read his decision to the court Monday, concluding that the Crown did not prove its case beyond a reasonable doubt.

He cited concerns with the complainant含羞草研究社檚 memory of what happened more than 30 years ago, and a lack of evidence to corroborate her account.

含羞草研究社淭here are just too many problems, and I含羞草研究社檓 not in the business of 含羞草研究社� declaring what happened. That含羞草研究社檚 not my job, you know, my job is to just decide whether or not guilt has been proven to the requisite standard, and it hasn含羞草研究社檛,含羞草研究社� Webber said.

Outside court, lawyer Brian Greenspan said his client was gratified by the 含羞草研究社渃lear, decisive vindication of his steadfast position that he was not guilty of these false accusations.含羞草研究社�

He also blasted the military for failing to reciprocate the loyalty Edmundson showed the institution throughout his 38-year career.

含羞草研究社淪enior military leadership and the media rushed to judgment, assuming the truth of these allegations rather than upholding the presumption of innocence,含羞草研究社� he said.

A tearful Viau told reporters outside court that the verdict was hard for her to hear but she found healing in the judicial process.

含羞草研究社淚 don含羞草研究社檛 regret bringing this complaint forward. I told the truth and I stand strong, knowing that all of this was not done in vain,含羞草研究社� she said.

She said more work must happen before the military is considered a safe working environment and commended those who are doing that work.

During the trial, Viau testified that one of her responsibilities on the ship during the 1991 deployment was to wake officers for night watch and overnight duties, and that she woke Edmundson regularly.

She told the court that his behaviour during those wake-up calls became worse over time, and that one night she found him completely exposed on top of the sheets.

Viau said she 含羞草研究社渨ent berserk,含羞草研究社� yelling at him and turning on the lights to wake the other officer sleeping in the top bunk.

That alleged incident was the basis for the indecent act charge.

Webber said he did not believe that Viau could have caused such a disruption on board a navy ship at night without notice from others.

含羞草研究社淚 conclude that (Viau含羞草研究社檚) overall evidence on the allegation that Mr. Edmundson did progressively expose himself to her as being far too compromised to approach proof of those allegations that she has made,含羞草研究社� he said in his decision.

Viau alleged that the sexual assault happened a couple of days later.

On the stand, Edmundson denied that any contact happened.

A key issue at trial was the credibility of the Crown含羞草研究社檚 corroborating witness.

The woman, whose name is protected by a court-ordered publication ban, did an interview with CBC News in 2021 as part of a story about Viau含羞草研究社檚 allegations.

But at trial, Greenspan produced a transcript of that interview that he said shows the reporter provided the witness with corroborating details.

In his decision, Webber said the woman含羞草研究社檚 evidence 含羞草研究社渃annot be relied upon in any respect to corroborate that evidence of the complainant, because it含羞草研究社檚 clearly a tainted recollection, doesn含羞草研究社檛 represent a real memory.含羞草研究社�

Edmundson stepped down from his position as head of military personnel after the accusation against him was made public in 2021.

He testified that in February 2022, he was directed by the chief of the defence staff to retire from the Armed Forces.

Edmundson was one of several senior military leaders accused of sexual misconduct in early 2021.

The crisis led to an external review by former Supreme Court justice Louise Arbour in May 2022, whose report called for sweeping changes to reform the toxic culture of the Armed Forces.

Gen. Jennie Carignan served as chief of professional conduct and culture, a role created to execute proposed reforms recommended in the Arbour report, before she was promoted as chief of the defence staff in July.

Outside court on Monday, Viau含羞草研究社檚 lawyer Emilie Taman said she was surprised the judge rejected Viau含羞草研究社檚 testimony that the culture in the navy in 1991 was hostile to women.

含羞草研究社淗e preferred the evidence of senior officers, whose experience surely would have been very different, and used that to undermine her credibility in a way that just really doesn含羞草研究社檛 accord with what we含羞草研究社檝e come to know about the culture in the Forces,含羞草研究社� she said.

Defence Minister Bill Blair said the government is committed to the reforms laid out in the Arbour report and to supporting Viau, whom he called a survivor.

含羞草研究社淢y concern is in making sure that we provide the appropriate supports for her now,含羞草研究社� he told reporters on Parliament Hill.

含羞草研究社淚 can only imagine how traumatic the entire experience has been for her, including in the criminal justice system.含羞草研究社�

Edmundson declined to comment Monday on whether he was considering legal action against the government or the military.

Two of the other former senior leaders who faced accusations of misconduct have sued.

Former major-general Dany Fortin, who was acquitted in 2022 of a sexual assault allegation that dated back to 1988, settled a lawsuit with the federal government for an undisclosed amount last year.

In May, Lt.-Gen. Steven Whelan filed a lawsuit against his accuser and the federal government. Whelan was charged with conduct to the prejudice of good order and discipline but the military prosecutors dropped the charges during a court martial last fall.
