The low level of terrorist activity in Poland has not stopped it legislating in the wake of the recent terror attacks in Europe. This chapter begins with an outline of the historical development of counter-terrorism law and policy in Poland prior to 9/11, before providing a synopsis of post-9/11 domestic and European Union legislation. The final section examines the types of contagion according to the categories set out in Chapter 1. Recent years have seen a series of dramatic reforms of the Polish criminal justice system on the basis of the terrorist threat creating conditions for violations of the rights to liberty, privacy, and so on. In this more recent legislation, the chapter finds strong evidence in support of the ‘contagion’ thesis, particularly in a political context where core democratic guarantees appear under threat.
