During the concession phase, the port authority often plays two roles. On the one hand, the port authority serves the public interest as the regulator overseeing the delivery under the concession agreement. On the other hand, the port authority may participate in a public-private relationship with a private user of the port of the port. There is a growing trend for port authorities to become commercial players who interact with private terminal operators as economic partners rather than as regulators. This trend arose from the need for port authorities and terminal operators to need each other. As a result, it is very difficult to strike the right balance between regulatory relations and the commercial interests of both parties. In this context, the rights and obligations of the port authority were modelled as part of an owner`s port model. Most of the time, the current legislation of the concession contract is the national law of the country in which the terminal is located. However, some foreign lenders require that the documentation be submitted to the United Kingdom [BCJ7] or U.S. law. Legal issues, submission to jurisdiction and dispute resolution should be addressed at an early stage of negotiations between the Port Authority and the operator, particularly in the case of a concession on a bot agreement (see Box 38). The more attractive and profitable a concession is, the more likely it is that a government will offer tax breaks and other incentives.
Basic structures: all land, with the exception of land subject to the right of rental. Basic structures include all pieces of stone, foundation remains, pylons, pipes, cables, scaffolding, paving stones, demarcations and works on or on the site, created, installed or built by the port authority or former users prior to the start of the lease right. A concession or concession contract is the granting of rights, land or property by a government, a local authority, an entity, a natural person or any other legal person.  The terms of a concession contract depend largely on his desire. For example, a contract to operate a food concession in a popular stadium cannot offer much to the dealer in the kind of incentives. On the other hand, a government that wants to attract mining companies to an impoverished area could offer significant incentives. These incentives could include tax breaks and a lower royalty rate. For example, there is a concession contract between the French and British governments and two private companies via the Channel Tunnel.
