No further action will be taken by Tasmania's Labor opposition against short-lived leader David O'Byrne following an investigation into sexual harassment allegations.
Mr O'Byrne was appointed to the position in June in the wake of Labor's third straight election loss but resigned as leader in early July after the accusations came to light.
He was accused of sending inappropriate text messages to a junior employee and kissing her without consent in 2007 and 2008, when he worked for the Liquor, Hospitality and Miscellaneous Union.
Mr O'Byrne issued a public apology when he stepped down, saying he thought at the time his conduct was consensual but now understood it was not.
Labor state secretary Stuart Benson said on Tuesday he'd received the findings of an independent investigation into the allegations.
"I have accepted the key findings and recommendations," he said in a statement.
"The key findings and recommendations have been sent to the complainant and the respondent. I now consider this investigation to be finalised with no further action required."
Mr Benson said he was obliged to abide by strict confidentiality clauses involved in Labor's complaint process and would not comment in detail.
"These clauses exist to protect people who come forward and for the interests of due process, procedural fairness and natural justice for all parties," he said.
"On legal advice, respect to the complainant and respondent and to abide by the confidentiality provisions of the policy, I am not able to make any further public statements about the matter."
Mr Benson noted the investigation was undertaken by former Fair Work commissioner Barbara Deegan who has "no conflict of interest or connections" to Labor.
Mr O'Bryne, who represents the southern electorate of Franklin, has remained on the backbench since stepping down.
He was elected Labor leader following the party's May 1 election loss under Rebecca White, who has since been reinstated to the top job.
