Which institution meets in the Palace of Westminster and consists of life peers and hereditary peers?

The institution that meets in the Palace of Westminster and consists of life peers and hereditary peers is the House of Lords. This chamber is one of the two houses of the Parliament of the United Kingdom and plays a crucial role in reviewing legislation proposed by the House of Commons. Life peers are appointed for their lifetime and usually hold expertise or distinguished service in various fields, while hereditary peers inherit their titles. Although there are restrictions on the number of hereditary peers who can sit in the House of Lords, this mix of appointed and hereditary members distinguishes it from other legislative bodies such as the House of Commons, which is made up solely of elected members, or the Senate and House of Representatives, which are part of the United States Congress.
