The field of public family support plays a major role in Austrian social security policy. The amendment of the FLAG, which was part of the Budgetbegleitgesetz 2011, changed it decisively. Due to economic measures the amount and period of entitlement for public family support was reduced. This diploma thesis deals with these current changes and focuses on family allowance for students, for they are affected especially by this reduction. The field of public family support is a legal cross-sectoral topic and will therefore be discussed with particular regard to social security law, administrative law and constitutional law. Issues of legal and social security policies will be analysed on the basis of legal norms, guidelines, legal practice, relevant literature and comments. The thesis will describe the prevailing legal norms, deal with legal ambiguities and put possible solutions forward. Chapter 2 will focus on the development of public family support in Austria and illustrate its political background, history, legal norms and system. In Chapter 3, the current legal situation and general eligibility requirements for family allowance will be described. Chapter 4 will deal with the legal changes resulting from the amendment of the FLAG. In Chapter 5, the complex legal situation of family allowance for students, which is of major importance in practice, will be explained in detail including the amended legal norms. Relevant issues of constitutional law and corresponding decisions of the Constitutional Court will be discussed in Chapter 6.
