A former union employee who accused Tasmania's short-lived Labor opposition leader David O'Byrne of sexual harassment says she has no faith in an independent investigation into the claims.
Mr O'Byrne will continue to serve in parliament after the party's state secretary deemed "no further action" was needed following the probe.
Mr O'Byrne was appointed leader in June in the wake of Labor's third straight state election loss but stepped down from the role in early July after the allegations came to light.
He was accused of sending inappropriate text messages to Rachel Midson and kissing her without consent in 2007 and 2008 when the pair worked for the Liquor, Hospitality and Miscellaneous Union.
Labor state secretary Stuart Benson said he accepted the findings and recommendations of the investigation but was unable to provide details because of strict legal confidentiality requirements.
"The key findings and recommendations have been sent to the complainant and the respondent," he said in a statement on Tuesday.
"I now consider this investigation to be finalised with no further action required."
Mr O'Byrne, who is now on the backbench, has doubled down on earlier comments, saying he thought at the time the conduct was consensual.
"I acknowledge I shouldn't have engaged in that contact," he told reporters.
"At the time I genuinely believed they were consensual, Rachel has now said they're not. I'm not going to question her judgement on that.
"I do reject her assertions that I sexually harassed her and victimised her. The investigation clearly showed that I did not do that."
Speaking to media, Ms Midson said she had "no faith" in the investigation or its outcome.
"I did not ask for, or invite, any of the admitted behaviour from a man 15 years my senior," she said.
"(He) was married with two young children and had a significant amount of power over me in my workplace.
"I feel physically sick that this report has found that there was a consensual atmosphere about the interactions between myself and David.
"Nothing could be further from the truth. I never wanted this behaviour to happen to me.
"This outcome essentially means that, as a woman, if you are personable and friendly to everyone in the workplace, that you become fair game."
Mr O'Byrne, who represents the southern electorate of Franklin, was elected Labor leader following the party's May 1 election loss under Rebecca White.
Ms White, who has since been reinstated to the top job, acknowledged it "has been a difficult time for the individuals involved and the Labor party more broadly".
"I also acknowledge the investigator has concluded that no further action is required," she said.
"David O'Byrne has a clear commitment to Tasmania and will continue his strong work in the electorate of Franklin as a member of the parliamentary Labor team."
Mr Benson noted the investigation was undertaken by former Fair Work commissioner Barbara Deegan who has "no conflict of interest or connections" to Labor.
