This paper examines Ireland's 2004 Constitutional Amendment which removes birthright citizenship from any future Irish-born children of immigrant parents. I argue that for particular historical reasons, the ability of the state to convince its citizens of the necessity for this Amendment was remarkable and I suggest that it was able to do so by constructing citizenship as a moral regime and foreign-nationals and their foetuses as 'suspect patriots.' I describe how the notion of immorality is laminated upon black bodies -specifically black pregnant women -and how the presence of black migrant workers, refugees and asylees consequently comes to be experienced in Irish national space as transgressive, their political subjecthood constrained by the supposedly legible abjectivity of their bodies. The issue of race remains unenunciated, and yet, as the Minister for Justice stated during the referendum debate, 'anyone with eyes can see the problem.' The Irish government's privileging of moral rather than cultural incommensurability is strikingly similar to culturalist rhetorics of exclusion that are often invoked when race is at issue in European public debate on immigration. Configured upon, and therefore experienced as a type of body, immorality becomes an alibi for race and is naturalized as a form of exclusion and as a potential site of state intervention in the form of xenophobic legislation and policymaking. Reading this decision as merely racist however, fails to give voice to the experiences of Irish Citizens who voted for this Amendment. Their struggle to build a "New Ireland" and to accept a multiculturalist framework in the face of neo-liberal restructuring policies and a European-wide retreat from the welfare state must be considered as being in dialectical tension with the ideological smearing of immigrants if we are to fully grasp the complex interaction between relations of power and the privileging of difference.
