Support with a tilt is condemned initially according to law (10)
I believe the answer is:
legalistic
'condemned initially according to law' is the definition.
I can't judge whether this definition defines the answer.
'support with a tilt is' is the wordplay.
I cannot quite understand how this works, but
'support' could be 'leg' (leg is a kind of support) and 'leg' is located in the answer.
'a' is within the answer.
'is' is within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for legalistic that I've seen before include "Excessively adhering to the law" , "strictly adhering to law" .)
