La réflexion juridique relative aux opportunités d’affaires est traditionnellement cantonnée au domaine qui a vu leur émergence : le droit des relations fiduciaires. Dans ce cadre, une opportunités d'affaires est traditionnellement regardée comme une chance captée par le dirigeant social. Mais n’est-il pas souhaitable de donner à la notion d’opportunité d’affaires une dimension plus large ? Une opportunité d’affaires est en effet une occasion de s’engager dans une opération ou une activité. En tant que chance économique, une opportunité d’affaires émerge sur le marché. À quelle condition, néanmoins, une occasion de contracter peut-elle être jugée opportune par celui qui s’apprête à la saisir ? Toute opportunité est-elle, par ailleurs, librement saisissable ? Quel est, autrement dit, le traitement juridique des opportunités d’affaires ? Identifier une opportunité d’affaires consiste à déterminer si une opération ou une activité est ou non opportune pour celui qui est appelé à la saisir. En toute hypothèse, le droit contrôle les moyens de l’identification d’une opportunité d’affaires, l’identification d’une opportunité d’affaires ne doit pas être l’occasion de tous les excès. Le traitement juridique des opportunités d’affaires est double. Au terme de sa fonction traditionnelle d’interdiction, le droit dissuade la captation d’une opportunité d’affaires. Mais embrassant désormais une perspective complémentaire de celle qui est classiquement la sienne, le droit reçoit pour mission d’inciter à saisir des opportunités d’affaires. Le sens de l’étude est ainsi de révéler l’appréhension, bien plus large qu’il n’y paraît, des opportunités d’affaires par le droit privé / Legal thinking about business opportunities is traditionally confined to the field that has emerged: the law of fiduciary relationships. In this context, a business opportunity is traditionally viewed as a chance captured by the social leader. But is it not desirable to give the notion of business opportunity a broader dimension? A business opportunity is indeed an opportunity to engage in an operation or activity. As an economic opportunity, a business opportunity emerges on the market. On what condition, however, can an opportunity to contract be considered opportune by the person who is about to seize it? Is every opportunity, moreover, freely seizable? What is, in other words, the legal treatment of business opportunities? Identifying a business opportunity is to determine whether or not an operation or activity is appropriate for the person who is called upon to seize it. In any case, the law controls the means of identifying a business opportunity, the identification of a business opportunity should not be an opportunity for all excesses. The legal treatment of business opportunities is twofold. At the end of its traditional interdiction function, the law discourages the capture of a business opportunity. But now embracing a perspective complementary to that which is classically his own, the law's mission is to encourage the seizure of business opportunities. The meaning of the study is thus to reveal the apprehension, much wider than it seems, of business opportunities by private law

A legally protectable trade secret is secret information which is applicable in trade or industry, in respect of which the owner has the will to keep it secret, which has economic value, and which is concrete enough to be embodied in a tangible form and to exist separately form its owner. A comparative study reveals that while trade secrets can be infringed in three ways - namely unauthorized acquisition, use and disclosure - contemporary legal systems differ in respect of both the ambit and juridical bases of protection against such infringing conduct. The legal protection of trade secrets is promoted by the recognition of a subjective right to the trade secret. This right is an intellectual property right independent of statutory intellectual property rights like patent rights and copyright, the common law intellectual property right to goodwill, and the personality right to privacy. In South African private law, trade secrets can be adequately protected by the application of general delictual and contractual principles. Delictual wrongfulness of trade secret misappropriation is constituted by an infringement of the right to the trade secret. Thus any act that interferes with the powers of use, enjoyment and disposal exercised by someone with a subjective right to that trade secret, is, in the absence of legal grounds justifying such interference, wrongful. Patrim·onial loss caused by both intentional and negligent infringement of trade secrets should be actionable under the actio legis Aquiliae. Wrongful trade secret infringements can - also in the absence of fault on the part of the infringer - be prevented by an interdict. Protection of trade secrets is not restricted to the contexts of either unlawful competition, or fiduciary relationships. Trade secret protection is on a sound footing in South African law, compares favourably with the position in other legal systems, and is in step with the international agreement on Trade-Related Aspects of Intellectual Property Rights to which South Africa is a signatory nation. / Private Law / LL.D.
