You need pre-internet cases from the era before courts had websites. Also, court rules generally require citation formats that use page numbers from the official reporters. In the past, the West has actually unsuccessfully tried to claim copyright to its page numbers (West Publishing Co. v. Mead Data Central, 799 F.2d 1219).
