Former court sessions (7)
I believe the answer is:
assizes
'former court sessions' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for assizes that I've seen before include "Old county court sessions chaired by itinerant judges" , "Former court sessions" , "Old county courts of England" , "Judicial sessions (hist.)" , "Precursor of Crown Courts" .)
