This revised edition of the Law on General Terms and Conditions faithfully reflects the wave of judicial decisions and accompanying jurisprudential discussion taking place in this area. In the Commentary on § 305 of the BGB (German Civil Code), the differentiation between AGB (general terms and conditions) and individual agreements has been significantly expanded in the light of the most recent debates. Greater attention is also given to the admissibility of supplementary contractual interpretation in § 306. The revised edition spotlights the connections and interactions between legal decisions in specific cases and the comprehensive principles of the Law on General Terms and Conditions within the scope of the General Clause under § 307 of the BGB, including practice-relevant issues pertaining to energy supply contracts and collateral price agreements by banks. Interconnections between international and procedural issues are made clear for managing contractual clauses dealing with place of jurisdiction and choice of legal venue. The commentary on the catalogue of clauses in §§ 308 and 309 of the BGB reflects the extensive casuistry that has developed in recent years, particularly against the background of the new Law of Obligations. An entirely separate section is now devoted to questions pertaining to the review of terms and conditions under labor law.
