I believe the answer is:

indifference

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

'lack of concern' is the definition.
(I've seen this before)

'encapsulated by dispute' is the wordplay.
'encapsulated by' becomes 'in' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'dispute' becomes 'difference' (synonyms).
'in'+'difference'='INDIFFERENCE'

Can you help me to learn more?

(Other definitions for indifference that I've seen before include "Lack of interest" , "Lack of concern" , "Lack of involvement" , "Unconcern" .)

I've seen this clue in The Times.
