This chapter considers the fourth and final form of backlash discussed in the book: doctrinal challenges. Using examples from the European Court of Human Rights, this chapter considers how and why doctrinal challenges, or challenges that dilute the ability of human rights and criminal courts to affect domestic policy change, constitute a form of backlash. The chapter begins with a case study of Russia and the European Court of Human Rights and goes on to provides examples from the United Kingdom and Denmark. As this chapter shows, backlash politics can come from both traditional foes as well as long-standing supporters.
