 Despite its popularity, many object to A4R. A fundamental objection questions the assumption that motivates A4R – that arriving at agreement on a decision-procedure is more feasible than arriving at consensus on substantive values (Friedman 2008; Dawson and Verweij 2014; Sabik and Lie 2008). Others debate whether the publicity and revision and appeals conditions are sufficiently democratic (Friedman 2008, 102) or whether publicity is necessary for legitimacy (de Fine Licht 2011; Martin and Giacomini and Singer 2002).
