QUORUM

n. minimum number of persons required to be present in order to conduct business legally

In law, a quorum is the minimum number of members of a deliberative body necessary to conduct the business of that group. Ordinarily, this is a majority of the people expected to be there, although many bodies may have a lower or higher quorum. Two countries that have had previous troubles with quorums are the United Kingdom and the United States of America.
