THE House of Lords will not be investigating complaints that Lord Kilclooney breached its code of conduct.
Life peer Lord Kilclooney has already defended referring to Taoiseach Leo Varadkar as a "typical Indian".
Former senior Ulster Unionist John Taylor (80) tweeted the remark in May in response to claims by the DUP that Mr Varadkar's visit to the north demonstrated "poor manners".
Lord Kilclooney has served at every level of politics and is now a cross bench peer.
Following strong criticism of the tweet, the peer insisted his "typical Indian" remark was "not racist as he himself has confirmed that he is half Indian".
Last November, Lord Kilclooney was forced to withdraw a tweet in which he described Mr Varadkar as "the Indian".
In a letter to East Derry SDLP Assembly Member John Dallat, the Commissioner for Standards said she would not investigate.
"The House of Lords Code of Conduct covers members’ parliamentary activities. It does not extend to their performance of duties unrelated to parliamentary proceedings," said Lucy Scott-Moncrieff.
Mr Dallat expressed his disappointment.
