The end of a contract, the Eschatocol (or final protocol), is often marked by a clause such as “in the knowledge of witnesses” or “in faith, of what”, the parties have affixed their signatures, followed by the words “DONE at”, and then the place (s) of the execution of the contract and the date (s) of its execution. The date is usually written in the most formal, non-digital form. For example, the Charter of the United Nations was “DONE in the city of San Francisco on the twenty-sixth day of June, one thousand nine hundred and fifty-five.” When the contract is executed in several copies in different languages, this fact is always taken into account and the provision is that versions are also mandatory in different languages. A contract is an official and explicit written agreement that states use to engage legally.  A treaty is an official document that expresses agreement in words; It is also the objective result of a solemn event that recognizes the parties and their defined relationships. The publication of a contract does not require academic accreditation or interdisciplinary background knowledge. IpPC is a contract to prevent the introduction and spread of pests to plants and plant products and currently has 177 government recipients. IPPC has developed plant health guidelines and serves as a reporting centre and source of information. Seven regional plant protection organizations have been established under the aegis of ipPC. For example, the North American Plant Protection Organization (NAPPO) consists of the United States, Canada and Mexico, which participate through APHIS, the Canadian Food Inspection Agency (CFIA) and the Plant Health Directorate. The European and Mediterranean Organization for the Protection of Plants (EPPO) is an intergovernmental organisation that is also responsible, within the framework of the IPPC, for plant health cooperation between 50 countries in the European and Mediterranean region.
International agreements are formal agreements or commitments between two or more countries. An agreement between two countries is described as “bilateral,” while an agreement between several countries is “multilateral.” Countries bound by countries bound by an international convention are generally referred to as “Parties.” International courts and arbitrators are often called upon to resolve key disputes over interpretations of the contract. In order to determine its importance, these judicial bodies can examine for themselves the preparatory work for the negotiation and development of the treaty as well as the final contract signed. Ratification is an act by which the state expresses its final consent to the contractual commitment.
