I agree with S200 . Also might be helpful to know the benefits and limitation of courts making precedent, e.g. benefit: common law principles that align with social values can be applied to similar cases where the material facts are similar
limitation: Parliament, as the supreme law making body can abolish those precedents...elaborate on how that is ineffective/a weakness to effective law making, a principle of justice, etc (depending on what the question is asking).
Yes, judges use precedent as a reference if it is binding precedent. For persuasive precedent, they do not have to, though I have heard they are usually (not always) influenced by those precedents.
