A bicameral legislature consists of two chambers (e.g., the House of Commons and the House of Lords in the UK, or the Senate and House of Representatives in Nigeria). While this system provides a check and balance within the legislature, one of its demerits is that it can delay the passage of bills. This happens because a bill has to go through both chambers before it can become law, which can lead to lengthy debates and delays, especially if the two chambers disagree.
