History of the Czech presidency – Constitutional status of the President – Personal powers and powers subject to countersignature by the Premier – Presidency of V. Havel and V. Klaus – Emerging constitutional conventions – Appointment of judges – Resignation of Ministers and Appointment of Premier – Legislative veto – Moderation of the constitutional system rather than implementation of a political programme – Importance of the political context – Parliamentarianism with a relatively influential President.

Polish constitutional tradition concerning system of government mainly parliamentarian – Round Table before the Fall of the Wall in 1989 as explanation for the role attributed to the President – development towards a variety of ‘rationalised parliamentarianism’ with a relatively strong role for prime-minister in the 1997 Constitution – system of government not really semi-presidential in nature

A constitutional experiment in which a parliamentary system of government under proportional representation was combined with the direct election of a prime minister — the system prior to 1992 — the political context of the 1992 reform — the unintended consequences of the reform in practice — the return to a pure parliamentary form of government, combined with a constructive vote of no-confidence and a prime-ministerial power to dissolve parliament.

Influences of the Movimento das Forças Armadas, of earlier Portuguese and of foreign constitutions on Portuguese Constitution of 1976 — A semi-presidential system with originally four political powers: president, parliament, government and Revolutionary Council — Progressive ascendancy of the presidency in practice between 1976–1982 — Constitutional amendment of 1982: Revolutionary Council abrogated, parliamentary powers strengthened, presidential powers reduced — Presidential role in practice not declining, though depending on the political party power constellation — Influence of president as political moderator and institutional regulator at the lowest when political colours of president and parliamentary majority match — President not conducting, directly or indirectly, the country’s general policy.

The editorial board of the European Constitutional Law Review has solicited a number of contributions on presidential elements in government systems in Europe. At the origin of the project are some recent sweeping interventions of heads of state in the political arena. These are notably the (suspensive) veto of the domestic Act implementing the European Arrest Warrant Decision by Czech president Vaclav Klaus and the dissolution, against the will of both the government and the parliamentary majority, of the Assembleia da República by Portuguese president Jorge Sampaio in 2004. They excited our curiosity about the latent ingenuities of systems that we think to understand but of which we know so little.
