International action, such as may set a precedent? (4,4)
I believe the answer is:
test case
'a precedent?' is the definition.
(I've seen this before)
'international action such as may set' is the wordplay.
I cannot really understand how this works, but
'international' could be 'test' (as in a test match in cricket) and 'test' is found within the answer.
'action' could be 'case' (synonyms) and 'case' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for test case that I've seen before include "Legal action setting a precedent" , "Precedent-setting trial" , "Legal precedent setter" , "Cassette containing significant lawsuit" , "Legal action where the outcome will serve as a precedent" .)
