In Greece, the Supreme Special Court (Greek: Ανώτατο Ειδικό Δικαστήριο) is provided for in the article 100 of the Constitution of Greece. It is not a permanent court and it sits only when a case belonging to its special competence arises. It is regarded as the supreme "constitutional" and "electoral" court of Greece. Its decisions are irrevocable and binding for all the courts, including the Supreme Courts. However, the Supreme Special Court does not have an hierarchical relation with the three Supreme Courts (the Court of Cassation, the Council of State and the Chamber of Accounts). It is not considered higher than these courts and it does not belong to any branch (civil, penal, administrative) of the Greek justice system.
According to the article 100 of the Constitution the Supreme Special Court comprises eleven members. Namely:the presidents of the three Supreme Courts,
four members of the Court of Cassation, chosen by lot for a two-years term,
four members of the Council of State, chosen by lot for a two-years term.
The Court is presided over by the seniormost president of either the Court of Cassation or the Council of State.
When the Supreme Special Court: a) resolves the conflicts between the administration and the courts or between the administrative and the civil courts or between the Chamber of Accounts and the other courts, or b) resolves a dispute about the constitutionality of a legal provision or about the real meaning of a legal provision, then the Court comprises two extra members: two (full) professors of Law, appointed by lot.
The history of the Supreme Special Court is quite short, as it was first founded by the Constitution of 1975. Its organisation and function is regulated by the article 100 of the Constitution of 1975/1986/2001 and the Law 345/1976. Germs of this Court exist in the article 73 of the Constitution of 1952 (providing for a special electoral court) and in the constitutions of the military junta (1967-1974), providing for a special court resolving the disputes between the Supreme Courts.
The jurisdiction of the Supreme Special Court is strictly defined by the Constitution (article 100). Hence:It judges pleas against the validity of the results of the legislative elections
It controls the validity of the results of the referendums.
It decides the deposition of a member of the Parliament, according to the constitutional provisions.
It resolves the conflicts between the administration and the courts or between the administrative and the civil courts or between the Chamber of Accounts and the other courts
It resolves a dispute about the constitutionality of a legal provision or about the real meaning of a legal provision
It decides whether a rule of international law belongs to the customary international law.
Since the Supreme Special Court has the power to issue an irrevocable and binding decision, with which a member of the Parliament loses her or his position, it becomes the "supreme electoral court". According to the article 58 of the Constitution, the court examines pleas concerning electoral violations or lack of legal qualifications of candidates. It also controls whether a member of the Parliament has undertaken duties incompatible with her or his office. These incompatible duties are enumerated in article 57 of the Constitution. If the Supreme Special Court ascertains the incompatibility of the undertaken duties, the deputy loses her or his office "by operation of law".
In Greece every court controls the constitutionality of the laws and there is no "permanent" Supreme Constitutional Court, as in Spain, Germany etc. If any court judges a legal provision as "unconstitutional", it decides not to apply it, but it has not the power to declare the legal provision "null and void". This restriction is also binding for the Supreme Courts, which declare the unconstitutional legal provision "inapplicable". Nonetheless, if a case concerning the constitutionality of a law is introduced into the Supreme Special Court (after the issuing of contradictory decisions of the Supreme Courts), the Court has the constitutional right to declare an unconstitutional legal provision as "powerless". This means that the unconstitutional legal provision still exists (it is not formally "null and void"), but it is expelled from the Greek "law and order".
The decision of the Supreme Special Court, declaring the unconstitutionality of a legal provision is final, irrevocable, binding for every Greek court, including the Supreme Courts, and judges the matter once for ever. No court has the right to take a different decision for the same legal provision in the future. If a court of first instance or a court of appeals or even a Supreme Court had judged the same matter in a contradictory way before the issuing of the decision of the Supreme Special Court, it is obliged to reverse is judgement and to reissue it in accordance with the Supreme Special Court's decision.
The Supreme Special Court of article 100 must not be confused with the "Special Court" of article 86 of the Constitution. This last "Special Court" is an ad hoc court, competent to judge alleged criminal acts of members of government (previous or in service), committed in their official capacity only (i.e. not common criminal or civil offenses committed in their personal capacity) and only when impeached by Parliament. It is also competent to judge the President of the Republic, if impeached by Parliament for intentional violation of the Constitution or for high treason. In such cases, Parliament acts as the prosecuting attorney and the defendant(s) may be represented by lawyers of their choice, as in any court.
This "Special Court" comprises seven judges of the Court of Cassation and six judges of the Council of State, chosen by lot. It is presided over by the seniormost judge for the Court of Cassation.
