Retained EU Law (Revocation and Reform) Bill

I was not referring to the proper development of domestic law on this occasion. At the top of page 6, we seem to be asking courts to consider the extent to which EU case law “determined or influenced” in and of itself rather than about the “proper development” which is in new subjection (5)(c). I wonder whether that is, to use the language used by the noble Lord, Lord Kerr, prejudicial or leading the court.
