Elementos para a eficácia jurídica da pluralidade contratual

Abstract

This thesis aims to show that the contractualbinding, understood as the possibility of mutual interference between contracts, occurs by virtue of the conjunction of the law to the facts, not just by the simple economic integration between the underlying businesses, to characterize such binding from a legal point of view. The first source of contractual binding is the intention of the parties through contractual clauses. The parties, through private agreements may cause effects arising from a contract to interfere in another one. The second source is the law. Often the legislator or two or more contracts to connect so that together produce some effects. In these cases deviates from the will of the parties and supersedes the determination of the legislation. Finally, the contract binding can be an application of the principle of good faith. The confidence awakened in relationships where there is a high economic integration must be protected.
