A resolution is divided into three sections: the header, the pre-ambulatory clauses, and the operative clauses. The title comprises three pieces of information: the name of the committee, the topic of the resolution, and the country sponsoring the resolution. The committee name should be defined by statute or by rule of the body creating it. A committee may have any number of members, but no more than five individuals can serve on the committee at one time. The header usually takes the form of introductory language that identifies the subject of the resolution and often calls attention to its importance. For example, the header of a United States congressional resolution reads as follows: "Whereas, the government of Iraq has requested United States assistance in the aftermath of recent terrorist attacks against civilians; and Whereas, these attacks threaten the peace efforts being undertaken by the United States and other countries throughout the world." The preamble is included for informational purposes only and cannot be used to limit or expand the application of the resolution. For example, a preamble to an international treaty might state that the signatories intend to prohibit nuclear weapons tests in their territories, while at the same time allowing for the testing of nuclear weapons for peaceful purposes. The operative clauses set forth the action that will be taken by Congress or the organization's body of representatives.
