The most recent monography on partnership in Roman Law „Societas. Struktur und Typenvielfalt des römischen Gesellschaftsvertrages“ (by Franz-Stefan Meissel, a young Austrian Romanist) has been published in 2004., some thirty years after the last important book on this topic. It has been highly praised and has won the prestigious Premium Boulvert Romanist award. This monography does not bring about a dramatically different partnership theory like the monographies published in the previous century (Wieacker to Guarino). Instead, the author restricts himself to
analysis of a great number of different sources such as Roman jurisprudence, papirology, epigraphy and litarary sources. Author analyses these sources like Roman lawyer would – casuistically. In doing so he offers sevaral minor theses, e.g. that classification of partnerships found in the sources is only basic, and not the final list, given the plethora and flexibility of cases offered by Roman jurisprudence and other sources. On another occasion, he claims that partnership has certain outer effects
(Aussenwirkung), and that, consequently, it does not represent a purely internal relationship among contractual parties.
