The former federal Labor leader and NSW One Nation leader has described reports involving former partner Nathalie Matthews as "false, reckless and irresponsible".
Mr Latham has been the subject of Ms Matthews' reported allegations of a "sustained pattern" of abuse and manipulation as she seeks an apprehended domestic violence order against him.
"I have broken no law. The police did not involve themselves in the AVO matter," he told reporters on Saturday.
"I have breached no standing orders of the Legislative Council," he said.
"The NSW parliament has stringent processes about inappropriate behaviour, and in my six years there, I've never been notified of a complaint against me."
Ms Matthew's private application will be heard before a court on July 30, but no documents have been released to detail her untested assertions.
Police have not laid any charges against the MP.
But messages reportedly sent by the politician to Ms Matthews from the floor of parliament have been published.
The messages feature photos and derogatory comments about female MPs.
Mr Latham said he had apologised to Liberal member Susan Carter and Greens MP Abigail Boyd, and both had accepted his apology.
Some of Mr Latham's parliamentary colleagues claimed the controversial MP would be sacked if he worked anywhere else but others acknowledged they would still collaborate politically with him.
Premier Chris Minns said Mr Latham's "very troubling" behaviour would not be acceptable elsewhere, while senior minister Rose Jackson said MPs across the spectrum should shun him.
Opposition upper house leader Damien Tudehope has conditionally defended working with Mr Latham.
The government has flagged an inquiry into Mr Latham over unrelated alleged abuses of parliamentary privilege.
Mr Latham resigned from federal parliament in 2005 and left the Labor Party before being elected to the NSW upper house in 2019 as a One Nation member.
He quit that party in 2023, becoming an independent.
His term expires in 2031.
