My brother has been convicted and sentenced for something he didn’t do, and I wondered what can be done to prove his innocence?
You should discuss the chances of a successful appeal with your brother’s legal team. If he was convicted in a Magistrates’ Court (assuming he pleaded not guilty) he must submit the appeal notice to the Crown Court within 21 days. Time limits also apply in the Crown Court, and are adhered to, so there must not be any delay. An appeal to the Crown Court from the Magistrates is essentially an automatic right but if your brother wants to appeal a jury conviction in the Crown Court he will need the permission of the Court of Appeal to proceed. You should discuss your concerns with your brother’s solicitor immediately.
