Thank you for your query. I am sorry to hear of the situation you are now in.
Unfortunately, any application for permission to apply for Judicial Review does not extend your leave to remain lawfully and hence you are liable to report to the Home Office. So you are an overstayer from when you received your last Admin Review decision. While your application for permission to apply for Judicial Review is pending, you should not be detained but must continue to report to the Home Office.
If you succeed in your Judicial Review application, this means that your refusal letter is quashed, and the Home Office has to reconsider your case. It is then arguable that you do not become an overstayer and then can submit a new application while the Home Office makes a new decision, known as a variation application, or wait for a new decision from the Home Office. If the new decision is positive then good, if not, then you may be able to another Admin Review or submit a new application within 28 days from the date of refusal decision.As per Just Answer Expert policy, I am only able to give a generic advice.Please kindly rate my answer.
