ID card's not in order? That's harsh (10)
I believe the answer is:
discordant
'harsh' is the definition.
(thesaurus)
'id card's not in order?' is the wordplay.
'in order?' is an anagram indicator (the letters in a new order).
'id'+'cards'+'not'='idcardsnot'
'idcardsnot' is an anagram of 'DISCORDANT'.
'that's' acts as a link.
(Other definitions for discordant that I've seen before include "Lacking harmony; conflicting" , "off-key" , "Raucous" , "At variance" .)
