special interests v. public good

Representing particular interests to policy makers which are responsible for justifying their decisions eventually poses certain requirements. In an open policy environment where decision are made in - or at least acquainted to - the public an alignment with a certain special interest is nothing a policy maker can afford. That is as long as there is at least one competing special interest. This means that a special interest has to be nestled to the policy objective. Depending on the policy maker, a policy is more or less a solution for a societal problem which is a stumbling block on a society's pursuit of the public good. Therefore a special interest has to be nestled to the public good in order to increase its chances of being considered by a policy maker. But how to do that?
