The Pre Action Protocol, or PAP, is a notice to the Home Office of the possibility of Judicial Review proceedings. The Home Office is normally given 14 days to react to this pre-action protocol letter. The pre-action protocol’s goal is to avoid unnecessary litigation. The time restriction for filing a judicial review petition is 90 days from the date of the original refusal decision, and a pre-action protocol letter must be sent to the Home Office within that time frame.
