A call of the house is a motion which can be adopted by a deliberative assembly that has the authority to compel the attendance of its members in the absence of a quorum. The effect of the adoption of this motion is that the president of the assembly makes out arrest warrants which authorize the sergeant_at_arms to arrest any or all absent members and bring them to the meeting hall so that a quorum may be present. This motion is usually seen in houses of legislatures, such as the United States House of Representatives, since no normal voluntary associations have coercive power.
