 Many conceptions of equality operate along procedural lines involving a presumption of equality. More materially concrete, ethical approaches, as described in the next section below, are concerned with distributive criteria – the presumption of equality, in contrast, is a formal, procedural principle of construction located on a higher formal and argumentative level. What is at stake here is the question of the principle with which a material conception of justice should be constructed, particularly once the approaches described above prove inadequate. The presumption of equality is a prima facie principle of equal distribution for all goods politically suited for the process of public distribution. In the domain of political justice, all members of a given community, taken together as a collective body, have to decide centrally on the fair distribution of social goods, as well as on the distribution’s fair realization. Any claim to a particular distribution, including any existing distributive scheme, has to be impartially justified, i.e., no ownership should be recognized without justification. Applied to this political domain, the presumption of equality requires that everyone should get an equal share in the distribution unless certain types of differences are relevant and justify, through universally acceptable reasons, unequal shares. (With different terms and arguments, this principle is conceived as a presumption by Benn &amp; Peters (1959, 111) and by Bedau (1967, 19); as a relevant reasons approach by Williams (1973); as a conception of symmetry by Tugendhat (1993, 374; 1997, chap. 3); as default option by Hinsch (2002, chap. 5); for criticism of the presumption of equality, cf. Westen (1990, chap. 10).) This presumption results in a principle of prima facie equal distribution for all distributable goods. A strict principle of equal distribution is not required, but it is morally necessary to justify impartially any unequal distribution. The burden of proof lies on the side of those who favor any form of unequal distribution. (For a justification of the presumption in favor of equality s. Gosepath 2004, II.8.; Gosepath 2015.)
