When the Alabama legislature adjourned on April 18, 2006, House Bill 106 and Senate Bill 45 died. These identical bills purported to protect the right of teachers to "present scientific information pertaining to the full range of scientific views in any curricula or course of learning" and the right of students not to be "penalized in any way because he or she may subscribe to a particular position on any views." In language reminiscent of the Santorum language removed from the No Child Left Behind Act, they specified that "[t]he rights and privileges contained in this act apply when topics are taught that may generate controversy, such as biological or chemical origins." HB 106 and SB 45 closely resembled previous antievolution bills in Alabama -- three bills introduced in 2005 (HB 352, SB 240, and HB 716) and two bills introduced in 2004 (HB 391 and SB 336) -- all of which failed.
