Members of Parliament have been put on the spot over their treatment towards Mwende Mwinzi, whose appointment had almost split the country.
Mwinzi was appointed by President Uhuru Kenyatta as Kenya's ambassador to South Korea.
Despite having vetted and cleared her for the appointment, Defence and Foreign Relations committee under Katoo Ole Metito changed mind and called for the revocation of her appointment.
Mwinzi holds dual citizenship. She was born in America to one of a Kenyan parent, further complicating her plight to serve in Seoul.
In a statement published by The Elephant on Thursday, Kenyans in the diaspora accused MPs of unfairly treating the envoy, claiming that they had a vendetta against her.
"This narrow thinking completely misses the point that diplomatic spies and sell-outs do not need dual citizenship to act out of greed, dissatisfaction or unpatriotic inclinations. A study of the history of espionage should be exciting and enlightening for those in thrall to this sensationalist propaganda," they said.
"The Mwende case has been fraught with hypocrisy and dubious intentions on the part of the vetting Members of Parliament who have now insisted that she must surrender her American citizenship in order to take up office as Kenya’s Ambassador to South Korea."
Through Senior Counsel Prof Tom Ojienda, Mwinzi moved to court challenging the decision by the Defense Committee.
On Thursday, Justice James Makau ruled that ambassadors are public officers and not state officers, adding that Mwinzi should not renounce US citizenship.
"I have no hesitation to agree that citizenship by birth cannot be taken away by anyone."
He considered that the President had only appointed the nominee and the matter should be taken back to the National Assembly.
"Considering the position of the matter is still in progress. It's not complete and the process should be allowed to be completed" he ruled.
