Upheld amid innate disruption (10)
I believe the answer is:
maintained
'upheld' is the definition.
('maintain' can be a synonym of 'uphold')
'amid innate disruption' is the wordplay.
'disruption' indicates anagramming the letters.
'amid'+'innate'='amidinnate'
'amidinnate' with letters rearranged gives 'MAINTAINED'.
(Other definitions for maintained that I've seen before include "Declared; supported" , "Sustained" , "being kept going" , "Insisted" , "Kept up (level)" .)
