People in suits settled distressed giants (9)

I believe the answer is:

litigants

'people in suits' is the definition.
(people involved in legal suits)

'settled distressed giants' is the wordplay.
'settled' becomes 'lit' (I've seen this before).
'distressed' indicates anagramming the letters.
'giants' is an anagram of 'igants'.
'lit'+'igants'='LITIGANTS'

(Another definition for litigants that I've seen is " Parties to a lawsuit".)

I've seen this clue in The Guardian.
