This legal analysis constitutes the first part of a comprehensive comparative report on homophobia and discrimination on grounds of sexual orientation. The second part, a sociological analysis, is expected to be published by the end of 2008. Following an interdisciplinary methodology the Agency approached this challenging task by developing a legal analysis based on background material collected and analysed byits team of senior legal experts (FRALEX1) and a sociological analysis based on a variety of secondary data, as well as interviews with key actors, carried out by the Danish Institute for Human Rights (DIHR) and the international consultancy firm COWI.
