The changing fate of Polish civil procedure did not threaten the heritage of Polish jurisprudence. *****The adversarial and dispositive principles*****, as well as the principle of oral proceedings and the principle of the free appraisal of evidence were constantly present in the Polish legal system.

However, the attitude of the majority of Polish lawyers enabled many standards of the classic judicial proceedings to be maintained, and thereby also the relations with the European doctrine of procedural law.
