Law makingWatch this thread
Does anyone know the advantages and disadvantages of law making in parliament .
Laws made by Parliament are prospective in that they only have effect in the future, whereas judicial law-making is retrospective too which can result in appeals being made where the judges change the law. There is also the fact that Members of Parliament are democratically elected whereas judges are not, thus judges should not make laws because that would be undemocratic. This ties in with the idea that under the principle of the separation of powers, judges should not be making law since that is the function of the legislature (Parliament). Law made by Parliament are also subject to scrutiny before being implemented which is not the case for judicial law-making.
I think you may be able to find others with a little research, but those are a good starting point.
