In a unicameral legislature, the majority power is typically held by the party or coalition that holds the most seats, allowing them to dictate legislative priorities and decision-making. Unicameral systems, being composed of a single legislative body, streamline governance and can facilitate quicker passage of laws. The majority party often sets the agenda, controls committee membership, and influences the legislative process overall. This concentration of power can lead to efficiency but also raises concerns about the thoroughness of debate and the representation of minority viewpoints.
