Bad faith
Bad faith is important to the concept of original position in John Rawls' theory of justice, where mutual commitment of the parties requires that the parties cannot choose and agree to principles in bad faith, in that they have to be able, not just to live with and grudgingly accept, but to sincerely endorse the principles of justice; a party cannot take risks with principles he knows he will have difficulty voluntarily complying with, or they would be making an agreement in bad faith which is ruled out by the conditions of the original position.
