An Act to establish the Legal Services Commission, the Community Legal Service and the Criminal Defence Service; to amend the law of legal aid in Scotland; to make further provision about legal services; to make provision about appeals, courts, judges and court proceedings; to amend the law about magistrates and magistrates’ courts; and to make provision about immunity from action and costs and indemnities for certain officials exercising judicial functions.
Section 54 of the Act both creates and limits rights of appeal. One effect of this, as set out in the UK Supreme Court Practice Direction 1 is "The most important general restriction on rights of appeal is section 54(4) of the Access to Justice Act 1999. The effect of this provision is that the Supreme Court may not entertain any appeal against an order of the Court of Appeal refusing permission for an appeal to the Court of Appeal from a lower court. " which accords with Section 40(6) of the Constitutional Reform Act 2005
