Resort bad? Summon one who looks into complaints (9)
I believe the answer is:
ombudsman
'one who looks into complaints' is the definition.
(public official investigating complaints)
'resort bad? summon' is the wordplay.
'resort' is an anagram indicator.
'bad'+'summon'='badsummon'
'badsummon' is an anagram of 'OMBUDSMAN'.
(Other definitions for ombudsman that I've seen before include "Parliamentary commissioner" , "Complaint investigator" , "Official pursuing complaints against government departments" , "Official investigating complaints of maladministration" , "one appointed to investigate complaints" .)
