In an outlandish criticism of the UN High Commissioner, Navi Pillay, the Acting Secretary of the External Affairs Ministry, Kshenuka Senewiratne, said:

"The Government of Sri Lanka notes, with deep regret and concern, your statement delivered at the OHCHR Press Briefing on 18th January 2013 where reference has been made to Sri Lanka. At the outset, I wish to reject categorically the contents of this statement, as it lacks any semblance of objectivity, steeped as it is in bias, marred by erroneous facts and further compounded by the inappropriate tenor of its language, all of which are indicative of unequal and invidious treatment of Sri Lanka.

To me this is reminiscent of the action taken by MrHannyMegally following the visit of the OHCHR team to Sri Lanka in September 2012, when he deviated from the accepted practice, by de-briefing third parties, even before briefing you, in your capacity as High Commissioner, or the Permanent Representative of the country concerned.

It may also be recalled that when the latter pointed out the impropriety of this unacceptable conduct of Mr. Megally at that juncture, you accepted our Representative’s submission. However, your action in resorting to unwarranted comments with a series of innuendos on an issue which is entirely a domestic matter for Sri Lanka, and that too without first engaging with our Permanent Representative or the delegation of Sri Lanka in Geneva, demonstrates yet again the deviation from established procedure, amounting to blatant interference in an issue of a sovereign country."

The letter went on..

"Your assertion that “Sri Lanka has a long history of abuse of executive power” is offensive to this nation, and is clearly beyond your mandate. In this regard, you have transgressed the basic norms which should be observed by a discerning international civil servant, by bringing into question the constitutional governance of a sovereign State."
