Party discipline plays a crucial role in shaping legislative behavior. Strong party discipline encourages cohesion among members, ensuring that they vote in line with party policies and positions. This leads to more efficient decision-making and the ability to push significant legislation through parliament. Conversely, weak party discipline can result in factions within a party, leading to conflicts and difficulties in passing laws. In well-disciplined parties, members are less likely to deviate from the party line, but may also stifle individual representation of constituents’ interests.
