The Legal Aid for Crown Court Proceedings (Costs) Rules (Northern Ireland) 2005 (the 2005 Rules) provide for solicitors and barristers of legally aided defendants at the Crown Court to be remunerated through a system of standard fees, except where cases are certified by the Northern Ireland Legal Services Commission (NILSC) as being ‘very high cost’. Where this occurs, solicitors and barristers become entitled to special hourly rates and responsibility for assessing the fees payable to them transfers to the Supreme Court Taxing Master. Certification by the NILSC is on the basis that if the case "proceeds to trial that trial would be likely to exceed 25 days".
