A advantage is that it’s democratic as the laws are made by our elected representatives. If a general election isn’t performed as expected a gov can be voted out of the office.
Another advantage is that its full reform meaning acts of parliament can reform whole areas of law in one act this makes law easier to find
lastly act of parliament can set broad policies and give powers to other to make detailed rules known as delegated legislation, this is an ad general structure is laid down by parliament but it allows greater detail in law
A disadvantage is that gov is in control of the parliamentary timetable and allows very little time for private member bills that often deal with important moral issues even when a private member manages to introduce a bill it can be easily voted out by gov as they have majority of House of Commons the result is few private members bills become law and few moral issues are legislated upon
last disadvantage it’s a long process even where the job introduces a bill into parliament the process of becoming an act with all the different stages it takes several months, the original bill may be altered multiple times during parliamentary legislate process which means the final act is not as clear or comprehensive
Influence on parliamentary law making
pressure groups, represent the interests of a group of people, in 2007 laws against smoking in public places were made as of public/medical opinion, often bring scientific discoveries to govs attention. occasions of two pressure groups having conflicting interests.
Public opinion the views of members of general public this is a strong influence on parliam as 18+ able to vote. PO was mixed whether to leave the EU in 2016 majority voted to leave this allowed parliament to legislate in 2017 to allow this. When majority of public has certain beliefs
or demands, then parliament can safely pass legislation on the issue. gauging PO can be difficult no one can definitely say that majority public believe one way
