Book excerpt: One of the most topical questions in the legal systems is whether and to what extent fundamental rights impact our rights and obligations in our contractual relations. The European Union has integrated the Charter of Fundamental Rights into the Treaties of Rome and Lisbon. This book highlights whether and to what extent fundamental rights affect the position of citizens generally and in various fields of law, such as private (contractual) law, labour law,financial services, intellectual property rights, and the judicial protection in courts.
