“Upper House is permanent in Bi-Cameral Legislature”. How?
In the Bi-Cameral legislature there exists two Houses. One is known as the Lower House and the other is known as the Upper House. For example in India, the Lok Sabha is the Lower House of the Parliament. While the Rajya Sabha is the Upper House of the Parliament.
In most of the countries of the world like India, Canada, England where the Bi-Cameral legislature exists, the Upper House is permanent e.g. the House of Lords in Britain is hereditary. It never ceases to exist. The members to the Senate of Canada are nominated for the whole life. The one-third members of the Upper House i.e. the Rajya Sabha of India retire after every two years and in place of them the new members are elected. So. each member of the Rajya Sabha has the tenure of six years and the Rajya Sabha never dissolves.
