Proxy voting

Proxy voting is a form of voting whereby some members of a decision-making body may delegate their voting power to other members of the same body to vote in their absence, and/or to select additional representatives. A person so designated is called a "proxy" and the person designating him or her is called a "principal". Proxy appointments can be used to form a voting bloc that can exercise greater influence in deliberations or negotiations. Proxy voting is a particularly important practice with respect to corporations; in the United States, investment advisers often vote proxies on behalf of their client accounts.

The United States parliamentary manual Riddick's Rules of Procedure notes that, under proxy voting, voting for officers should be done by ballot, due to the difficulties involved in authentication if a member simply calls out, "I cast 17 votes for Mr. X."

Proxy voting is also an important feature in corporate governance through the proxy statement.

Legislatures

The rules of some assemblies presently forbid proxy voting. For example, in both houses of the U.S. Congress, as well as in most if not all state legislatures, each member must be present and cast his own vote for that vote to be counted. This can result, however, in the absence of a quorum and the need to compel attendance by a sufficient number of missing members to get a quorum. See call of the house.
