Ulrich G Schroeter (University of Freiberg – Faculty of Law) has posted “Vienna Sales Convention: Applicability to ‘Mixed Contracts’ and Interaction With the 1968 Brussels Convention” on SSRN; it originally appeared in the Vindobona Journal of International Commercial Law and Arbitration, Vol. 5, pp. 74-86, 2001. The abstract reads:
The present article discussed various questions pertaining to the interpretation of Article 3(1) and (2) of the United Nations Convention on Contracts for the International Sale of Goods of 11 April 1980 (CISG), the provisions which deal which so-called ‘mixed contracts’, i.e. contracts that involve elements of a ‘sale’ proper alongside obligations to manufacture or produce goods or to supply labour or other services.
In its second part, the paper elaborates on the interaction between the CISG’s provisions defining the place of performance (Articles 31 and 57 CISG) on one hand and Article 5(1) of the Brussels Convention of 27 September 1968 on Jurisdiction and the Recognition and Enforcement of Judgements in Civil and Commercial Matters and its successor, Article 5(1) of the EC Council Regulation 44/2001 of 22 December 2000 on the Recognition and Enforcement of Judgements in Civil and Commercial Matters on the other hand.
