The aim of the article is to indicate the prevalent features of the Polish process of constitutional and systemic changes in Poland in 1989-1997. It was assumed that the Polish process of constitutionalization was characterized by a number of specific features which were interrelated and dependent on each another. The aim of the paper is to recognize the phased character of the changes as the first feature of the political transformation process in Poland, whereas compromise should be regarded as its basic attribute. Other specific features (presented in the subsequent parts of the article) include: evolutionary, temporary, and pragmatic nature of the process.
