How to appeal
To bring an appeal to the Judicial Committee of the Privy Council, you must have been granted leave by the lower court whose decision you are appealing. In the absence of leave, permission to appeal must be granted by the Board. In some cases there is an appeal as of right and a slightly different procedure applies.
In civil cases, the lower court will generally grant you leave to appeal if the court is satisfied that your case raises a point of general public importance.
In criminal cases, it is unusual for the lower court to have the power to grant leave unless your case raises questions of great and general importance, or there has been some grave violation of the principles of natural justice.
