Establish disadvantageous position in court? (3,4)
I believe the answer is:
set down
'establish' is the definition.
(thesaurus)
'disadvantageous position in court?' is the wordplay.
I cannot really see how this works, but
'position' could be 'set' (set is a kind of position) and 'set' is found within the answer.
The remaining letters 'down' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for set down that I've seen before include "Record in writing" , "Placed" , "is allowed to alight" , "judge" , "position of losing tennis player" .)
