The idea of consummation as definitive of a marriage seems antiquated today. Yet, consummation operates as a central criterion in determinations of a ‘genuine marriage’ in Canadian immigration law. Drawing on the marriage and migration literature, theorizations of sexual citizenship, and critical multiculturalism, we explore recent judicial considerations of consummation in Canadian family sponsorship adjudications. We searched the CanLII database (a Canadian database of legislation and judicial records) for the keywords ‘non-consummation’ and ‘genuine marriage’ and identified 68 cases. Of these cases, three primary themes emerged: the use of consummation as a ‘technology of love’ – a requirement for assessing the authenticity of the spousal relationship and hence the worthiness of sponsorship; the discursive construction of sexual and gendered norms in expectations around marital intimacy, and the articulation of liberal tolerance and the cultural other in the assessments of genuine marriages among primarily racialized Canadians or permanent residents and their foreign spouses. We challenge these discursive narratives and conclude by arguing that instead of consummation as the basis for genuine marriage, the Law Commission of Canada’s ‘close personal relationship’ model is a better way to assess the ‘genuineness’ of relationships for determining Canadian citizenship.  相似文献

Among the more recognizable programs related to natural and sustainable food is the United States Department of Agriculture’s National Organic Program. Although the robustness of the organic food market is difficult to contest, many debate the extent to which U.S. organic policy outcomes adequately serve consumers and the organic agriculture producers they rely on. This paper engages the debate from the perspective of certified organic producers. Drawing on the results of a nationwide survey of USDA‐certified producers, we first provide a snapshot of how producers assess the environmental, consumer, and market impacts of U.S. organic food policy. We then examine the extent to which organic producers’ policy impact perceptions are associated with their alignment with an “organic ethos”—understood as producers’ commitment to core organic principles and the organic movement. The paper highlights producers’ values as perceptual filters and cognitive mechanisms that help shape producers’ policy impacts perceptions, illustrating a contributing factor to the enduring nature of organic policy debates.  相似文献
