Court order to BPO in appeal at North America (8)
I believe the answer is:
subpoena
'court order' is the definition.
'bpo in appeal at north america' is the wordplay.
'in' means one lot of letters goes inside another.
'appeal' becomes 'sue' (I've seen this before).
'at' means one lot of letters go next to another.
'north america' becomes 'na'.
'bpo' placed into 'sue' is 'subpoe'.
'subpoe'+'na'='SUBPOENA'
'to' acts as a link.
(Other definitions for subpoena that I've seen before include "Writ ordering court apperarance about bean soup" , "Write ordering someone to court" , ""Under penalty" (Latin)" , "Writ commanding person to appear in court" , "Writ requiring person to appear in court" .)
