Summaries in Afrikaans and English / Text in Afrikaans / In hierdie ondersoek is daar navorsing gedoen oor die aard en rol van fisiese beheer in die sakereg met die oog daarop om dit te omskryf en die funksies daarvan te identifiseer. By die verkryging van eiendomsreg word net vereis dat die fisiese beheer wat ten aansien van die saak uitgeoefen word, effektief moet wees. Of 'n saak effektief beheer word al dan nie, word aan die hand van die heersende verkeersopvattings getoets. Hierdie verkeersmaatstawwe wat in die praktyk ten aansien van bepaalde soorte sake uitgekristalliseer het, is buigsaam en veranderlik en dit maak dit moontlik dat die reg by maatskaplike en ekonomiese veranderinge aanpas. Die funksie van fisiese beheer in gevalle van verkryging is altyd publisiteit. In die geval van die beskerming van eiendomsreg word fisiese beheer besonder breed omskryf en daar word slegs verwag dat die persoon van wie die saak teruggeeis word, genoegsame beheer daaroor moet he om dit te kan teruggee. Die funksie van beheer is hier suiwer funksioneel. By die verlies van eiendomsreg speel fisiese beheer nie juis 'n besondere rol nie aangesien die verlies van beheer nie noodwendig op die verlies of beeindiging van eiendomsreg dui nie. Wanneer dit wel ter sprake kom, is die funksie daarvan publisiteit. In die geval van die verkryging van besit en houerskap, dien daarop gelet te word dat die enigste vereiste is dat beheer effektief moet wees en dit word weer eens aan die hand van verkeersmaatstawwe bepaal. Fisiese beheer word strenger omskryf vir verkryging as vir behoud. By die beskerming van besit en houerskap is die enigste vereiste wat gestel word dat beheer vreedsaam en ongestoord moes gewees het. Wanneer beheer oor 'n saak verloor word, gaan dit gewoonlik gepaard met die verlies van besit of houerskap. Die funksie van fisiese beheer is deurgaans publisiteit. Fisiese beheer word redelik streng omskryf vir doeleindes van 'n gewone pand en daar word gewoonlik vereis dat die pandsaak gelewer en gehou moet word vir die vestiging en behoud van 'n pandreg. Die funksies van beheer is hier sekuriteit en publisiteit. / This study examines the nature and role of physical control in the law of property with a view to defining this concept and identifying its functions. The only requirement for the acquisition of ownership is the exercise of effective physical control of the thing in question. Whether or not a thing is physically under control, is determined by the application of legal indicators deriving from use and custom. Such indicators as have cristallised in practice in respect of certain classes of things, are flexible and variable and enable the law to adjust to social and economical changes. The function of physical control in cases of acquisition is always publicity. The definition of physical control in cases of protection of ownership is particularly wide, the only requirement being that the person from whom the thing is reclaimed must have sufficient physical control of it to enable him to return it. The function of control is purely functional. Since loss of control does not necessarily indicate the termination or loss of ownerhip, physical control has no significant part to play in respect of loss, of ownership. Where it does come into play, however, its function will be publicity. In cases of acquisition of possession and holdership it is essential that physical control of the thing is effective and once again this will be determined by application of legal indicators. The definition of physical control is much narrower in respect of acquisition than in respect of retention. The only requisite for the protection of possession and holdership is peaceful and undisturbed physical control. Loss of control of a thing is usually indicative of loss of possession or holdership. Throughout the function of control is publicity. Physical control is quite narrowly defined in cases of ordinary pledge insofar as delivery and retention of the pledge object are usually required for the establishment and continuation of the pledge. In this instance, physical control serves the functions of both publicity and security. / Mercantile Law / LL.D.

Based on the premise ‘what we measure affects what we do’, this work seeks to address the following key question: What are the characteristics of the knowledge produced by the Rule of Law Index, WGI Rule of Law Indicator, Doing Business Indicators and the Global Competitiveness Index about the rule of law and business regulation respectively, and to what extent can this knowledge be used to assess and compare legal systems? My objective is to address the gap between, on the one hand, policy and scientific approaches to indicators and, on the other hand, legal scholarly approaches. The former tend to be specialized, mathematical and outcome-oriented, focusing on how to produce appropriate measures of social –and legal- phenomena. The latter assume an external point of view and are often verbal and critical. They focus generally on the genealogy, shortcomings and governance aspects of a particular set of indicators. This work provides new insights through a fourfold analysis: (i) an analysis of the context in which transnational legal indicators emerge, (ii) an analysis of their process of commensuration of legal phenomena, (iii) an analysis of their analytical value in jurisprudence and comparative legal studies, and (iv) an analysis of their normative effects on national legal systems. / Doctorat en Sciences juridiques / info:eu-repo/semantics/nonPublished
