A call of the house is a motion that can be adopted by a deliberative assembly. It has the authority to compel the attendance of absent members when a quorum is not present. The effect of the adoption of this motion is that the president of the assembly makes out arrest warrants that 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 Senate.
