Mr Mac Manu was leading a team of election observers from the Democratic Union of Africa to observe Kenya's August 8 election and also to share his electoral experience with Kenya’s opposition coalition, the National Super Alliance (NASA).
But he did not formally disembark from the plane and he was deported back to Ghana.
Commenting on the development and its impact on the diplomatic relation between Nairobi and Accra, Dr Danso told Accra-based Citi FM that deportation is an accepted norm in diplomacy.
Dr Danso, who is also the Dean of the Armed Forces Defence Command and Staff College said he could not comment on whether the Kenya authorities did the right in Mac Manu's deportation.
“They [Kenya] invite who they want and disallow who they don’t want. It’s a bonafide right… It is an accepted norm in diplomacy," he said.
"You look at the thing and think it will disturb your security, your political structure so you don’t want it… He is a persona non-grata so I won’t allow him entry. Period… I cannot say they did right or didn’t do right”, he added.
