Labour peer Peter Hain has been cleared of breaking parliamentary rules when he named the retail boss Sir Philip Green as the businessman accused of inappropriate behaviour towards staff.
Lord Hain used parliamentary privilege last October to name Sir Philip as the subject of a court injunction which was preventing the Daily Telegraph from identifying him in its reports of alleged sexual, racial and physical harassment.
Lawyers for the Arcadia chairman complained that the Labour peer had failed to declare his role as a global and governmental adviser to law firm Ince Gordon Dadds, who were acting for Telegraph Media Group in the case.
In a complaint to Lords Standards Commissioner Lucy Scott-Moncrieff, law firm Schillings said that Ince Gordon Dadds' involvement was "manifestly apparent" on the front page of the Appeal Court judgment imposing the injunction.
But Lord Hain insisted he did not know about the company's role in the case, and had not read the judgment.
He said he had made his decision to name Sir Philip "on moral considerations" after meeting one of his alleged victims.
"I was doing what I thought was morally right for the source, who had been treated terribly, and many others, according to what the source said and has subsequently been revealed on the record in a number of newspapers, shortly after what I said," Lord Hain told the Commissioner.
"I was not trying to second-guess the court, the lawyers or the judiciary at all."
In a report published on Monday, Ms Scott-Moncrieff dismissed the complaint, saying: "I accepted his assertion that he had not read the judgment, and was not aware of Ince Gordon Dadds' role in the legal proceedings.
"It would be unreasonable to censure him for failing to declare an interest of which he was unaware."
The Commissioner had previously rejected Schillings' complaint that Lord Hain was effectively providing parliamentary services for money when he spoke in the Upper House last October.
And she said complaints that he had abused parliamentary privilege were not matters for her to judge.
In response, Lord Hain said: "Sir Philip's complaint always was a malevolent ruse to divert attention from the harassment allegations against him by his employees.
"I'm grateful to the Standards Commissioner for finding that the complaint was entirely false."
