Summon bean soup maker (8)
I believe the answer is:
subpoena
'summon' is the definition.
(thesaurus)
'bean soup maker' is the wordplay.
'maker' indicates an anagram (can make this from the letters).
'bean'+'soup'='beansoup'
'beansoup' anagrammed gives 'SUBPOENA'.
(Other definitions for subpoena that I've seen before include "Court-attendance order" , "This may help build evidence" , "Writ ordering someone to attend a court" , "Summons to appear in court" , ""Under penalty" (Latin)" .)
