Growing impact of the Constitutional Court's jurisprudence on Polish system of law brings deep changes to the image of law in this country. Various aspects of civil procedure have been one of the most important subject-matters of the constitutional decisions for the whole 20-year history of this body. The main aim of the paper is to analyze and to give some comments to the leading case-law issued in this field under the current Constitution of 1997. The author rises the questions about the relationship between some key legal notions of civil procedure on the one hand, and the content of the Constitution on the other, like e.g. the right to justice, the right to be heard, the access to justice, and fair trial. The outcome of the analyze shows that the principle of constitutional notions autonomy seems to be misused in view to justify manifest incoherence in the reasoning of the Constitutional Court, which breaks the integrality of the Civil Procedure Code.
