We are often asked to grant increases for an opinion of counsel in connection with an appeal application.
If your client was legally aided when the court considered the matter at first instance and there was authorisation to instruct counsel in those proceedings the previous grant of legal aid will cover an opinion from junior counsel (or senior counsel if senior was instructed with our approval) on the prospects of success of an appeal.
