All judicial review applications must be made in the High Court and have to be within three months of the final decision being made by the public body. You may need a lawyer to submit a formal letter setting out what it is alleged the public body has done which is thought to be unlawful, and what action it is proposed to remedy that. It is allowed for a lay person to write this letter themselves, but we recommend that you seek specialist legal advice. The organisation concerned will then be given 14 days to respond. The next step would be to make an application to the court for permission to proceed with the judicial review.
