The article analyzes the issue of qualifying culpa in contrahendo in private international law. The author draws attention to the difficulties associated with determining the legal nature of pre-contractual liability and the diversity of approaches to this issue in various legal systems.

The article analyzes the phenomenon of dépeçage in the Rome Convention on the Law Applicable to Contractual Obligations. The author discusses various interpretations of this concept, focusing on the liberal and restrictive approaches.

Based on the linguistic analysis of the Convention's provisions, the author advocates a restrictive understanding of dépeçage, allowing for dismemberment only in the case of contracts containing clearly separated, independent parts. In conclusion, the author emphasizes that this approach ensures greater legal certainty and is consistent with the principle of uniformity of the contract statute.

The review concerns Karol Weitz's monograph "National Jurisdiction in Civil Proceedings," which formed the basis of his habilitation. The author analyzes national jurisdiction as a legal institution, its place in the system of civil procedure, and specific issues related to its functions and significance. The reviewer positively assesses the distinction between international jurisdiction and jurisdictional authority, the analysis of the forum non conveniens concept, and the discussion of jurisdictional conflicts. However, he is critical of the solution regarding the lack of national jurisdiction resulting from an agreement on the jurisdiction of foreign courts. The overall assessment of the dissertation is highly positive, and the reviewer expresses confidence that the author's concepts will be permanently incorporated into Polish doctrine.
