Crowd, largely out of order, in area set aside for reporters (5,7)
I believe the answer is:
press gallery
'area set aside for reporters' is the definition.
(area in a court)
'crowd largely out of order' is the wordplay.
'crowd' becomes 'press' (to press can mean to crowd around).
'out of order' is an anagram indicator.
'largely' anagrammed gives 'gallery'.
'press'+'gallery'='PRESS-GALLERY'
'in' is the link.
(Other definitions for press gallery that I've seen before include "Where journalists look down on politicians?" , "Balcony for reporters" , "Reporters' area in stadium, parliament, etc" , "area for journalists" .)
