Law takes time to block representation (7)
I believe the answer is:
statute
'law' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for statute that I've seen before include "Act of law" , "Act of Parliament" , "Set taut (anag.)" , "Law, rule" , "Written law" .)
