A South Australian judge has resigned amid an investigation into a "complaint about his conduct".
Judge Timothy Heffernan, who had served on the District Court, resigned on May 17.
"As the Judge is no longer a judicial officer, the Judicial Conduct Commissioner was bound to terminate the investigation without making any findings," District Court Chief Judge Michael Evans said.
"The Court takes all complaints of inappropriate judicial conduct very seriously."
Chief Justice Chris Kourakis also issued a statement saying he could not comment about Judge Heffernan.
"However, speaking generally, the community rightly expects that those persons to whom it entrusts the administration of justice observe the highest standards of respectful and decent conduct, according to all with whom they interact the dignity to which they are entitled," he said in a statement.
"Any person who cannot meet those standards should not seek judicial office or expect to remain in office."
The authority's statement said it would continue to support affected employees and it was committed to providing a safe, inclusive and respectful workplace.
