State duty to promote welfare by securing a social order where justice guides institutions and inequalities are minimised. The State is constitutionally obliged to promote the welfare of the people by securing and protecting a social order in which justice - social, economic and political informs all national institutions. The State must, in particular, strive to minimise inequalities in income and endeavour to eliminate inequalities in status, facilities and opportunities among individuals and groups residing in different areas or engaged in different vocations.
