For this part of the question only - assume that whatever advice you give in answer to question a) above, Rahul would like to continue with his action for a declaration. The RCPRA 2024 gives power to the Secretary of State for Justice ('the SoS') to set court fees for bringing a challenge against the RCPRA 2024 by way of Statutory Instrument. The SoS makes a Statutory Instrument which sets the fee for a challenge to the RCPRA 2024 at 15,000, which Rahul cannot afford. The relevant Statutory Instrument further provides that no legal aid will be available to bring a challenge and that the government's case is not to be disclosed in advance of the hearing which will take place in private.
