Country judge occasionally has a legal requirement for secrecy (6)

I believe the answer is:

uganda

I'm a little stuck... Click here to teach me more about this clue!

'country' is the definition.
(I know that Uganda is a African country)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for uganda that I've seen before include "It was Idi Amin's country" , "Landlocked African state" , "E. African country" , "Country W. of Kenya" , "Landlocked Afr. country" .)

I've seen this clue in The Irish Times.
