According to the Constitution, the Constitutional Court (in Armenian Սահմանադրական դատարան) administrates constitutional justice, ensuring the supremacy of the Constitution and reviews the lawfulness of different laws and regulations in Armenia. It works on the basis of the Constitutional law of the Republic of Armenia on the constitutional court.
The Court may declare laws or regulations invalid if it determines that they conflict with a higher law or the Constitution of Armenia. You can only apply to the Constitutional Court when there is a final act of court, all judicial remedies have been exhausted, and you are challenging the constitutionality of legal acts applied in relation to you by court and that led to a violation of your fundamental rights and freedoms laid out in the Constitution of Armenia.
Only the Court and the institution that adopted the law or regulations can annul them. The Court can also choose the date from which a law has lost its force. For example, the Court may declare that the law you are complaining about was invalid all along and its application in your case violated your human rights. Or it can decide that the law will no longer be in force from the day of the judgement, but it was valid and in force when it was applied to you.
The decisions and judgements of the Constitutional Court are binding and they cannot be appealed.
