The Australian Contracts Database (open access on the FDFA website) can be accessed by theme and lists all bilateral and multilateral agreements to which Australia belongs, as well as information on the contractual process and integration into national legislation. Articles 46-53 of the Vienna Convention on Treaty Law define the only ways to declare treaties invalid – which is considered unenforceable and void in international law. A treaty is invalidated either because of the circumstances in which a State party has acceded to the treaty, or because of the very content of the treaty. Cancellation is separate from termination, suspension or termination (addressed above), all of which involve a change in the consent of the parties to a previously valid contract, not the nullity of that consent in the first place.

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. The text of the treaty can provide for how it takes effect. In general, treaties come into force once they have been signed and ratified by a number of parties.
Contracting parties may ratify a contract with reservations or other declarations, unless the provisions of the treaty limit these measures. One of the reservations is a country`s attempt to change certain contractual conditions, as they apply between it and other countries. For more information on international conventions, see this article on the Harvard Law Review, the Berkeley Law Research Guide and the UCLA Law Review in this article. Contracts sometimes contain self-fulfilling provisions, which means that the contract is automatically terminated if certain defined conditions are met. Some contracts should only be binding temporarily by the parties and will expire at some point.
