Retained EU Law (Revocation and Reform) Bill

On a technical, legal point, it would be helpful if the Government could set out the methodology that they have used to ensure that everything—whether it be by directive, by tertiary legislation or by any other way—has been identified. A detailed analysis of the methodology would be extremely helpful because we need to know how it has been done to know what level of assurance we can have in it. I have tried it myself and found it quite difficult. I would like to know what has been done. It obviously cannot be done now, but a detailed methodology would be very helpful.
