There are other important issues of formulation that rule-consequentialists face. One is the issue of whether rule-consequentialism should be formulated in terms of compliance with rules or in terms of acceptance of rules. Admittedly, the most important aspect of accepting rules is compliance with them. And early formulations of rule-consequentialism did indeed explicitly mention compliance. For example, they said an act is morally wrong if and only if it is forbidden by rules the compliance with which will maximize the good (or the expected good). (See Austin 1832; Brandt 1959; M. Singer 1955, 1961.)
