Strictness in interpreting most of our rights (6)
I believe the answer is:
rigour
'strictness' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for rigour that I've seen before include "Preciseness - severity" , "Sternness" , "Severity or strictness, perhaps of the law" , "Extreme care and thoroughness" , "Severity or stringency" .)
