Why is law making under two-house system of parliament more complicated and cumbersome than under a single house system of parliament?

Law making under a two-house system of parliament is more complicated and cumbersome because it requires approval from both chambers, which can have different political compositions and priorities. This often leads to lengthy debates, potential conflicts, and the need for compromise, delaying the legislative process. Additionally, the necessity for coordination and negotiation between the two houses can complicate the passage of laws, making it more difficult to achieve consensus. In contrast, a single-house system can streamline decision-making, allowing for quicker enactment of legislation.
