It results in one being free of charge (9)
I believe the answer is:
acquittal
'it results in one' is the definition.
The definition suggests a singular noun which matches the answer.
'free of charge' is the wordplay.
'free' becomes 'acquit' (to free from legal charges).
'of charge' becomes 'tal' (I am not sure about this - if you are sure you should believe this answer much more).
'acquit'+'tal'='ACQUITTAL'
'being' acts as a link.
Can you help me to learn more?
(Other definitions for acquittal that I've seen before include "Judgement of not guilty" , "Not-guilty verdict" , ""Innocent" verdict" , "Verdict of Not Guilty" , "Absolution" .)
