If the relationship between a service provider and its client is or is transformed into such a relationship, such a relationship may qualify as an employment contract, agency contract or partnership with potentially heavy legal and tax consequences for the client. For example, if a contract for the provision of services is qualified a posteriori as an employment contract, the customer may be held liable for these contributions in addition to the price paid for the provision of services. Appropriate provisions should therefore be included in the agreement to ensure that the parties remain independent contracting parties. The law often changes or is sometimes ambiguous (it is not uncommon for court decisions to conflict). In addition, it is not uncommon for a party who tries to avoid liability to invoke the nullization of a contractual term (or the entire contract). In order to prevent a provision that may be void from leading to the nullity of the entire contract, a salvatorial clause should be added. Such a salvatorial clause provides that, where a provision is found to be invalid, it shall not affect the validity of the other parts of the agreement which remain in full force. It may also require the parties to negotiate in good faith a valid alternative provision consistent with their original intent. All the clauses of an agreement are interpreted on each other by giving each one the importance that derives from the whole action. Where more than one contract is involved in a given transaction, the courts may give importance to a provision of one of those contracts, in accordance with the intention of the parties, as set out in the other contracts. Finally, in principle, the parties must comply not only with the explicit provisions of their contract, but also with all the conditions implicit therein, which are conditioned by equity, practice or law. Therefore, judges may discover obligations that have not been explicitly included in the contract, such as. B the obligation to guarantee the safety of passengers in an agreement on the provision of transport services.
The parties may anticipate disputes by inserting into their contract certain provisions which include the Tribunal`s room for manoeuvre in its interpretative task. For example, a clause in the entire agreement prevents the Tribunal from interpreting a contract of other exchanges between the parties or their conduct. . . .
