#lucyletby, state of play. Lucy Letby’s new barrister Mark McDonald is preparing an application to the CCRC. Sir David Davis MP is preparing action in the House of Commons. Lucy’s last appeal application was refused because it was based on science that was “known” prior to her trials. (1/2) (2/2) The air embolism science proves that a main part of the #lucyletby case was garbage. In the legal sense, there is no new evidence so no grounds for an appeal. In the UK, judges are lawmakers. They have painted themselves into a corner. A higher power must step in - parliament is sovereign.
