请问，关于英国法律的mischief rule和purposive approach

c) Mischief Rule

The mischief rule is an old version of the purposive approach. It means that to remedy the mischief, the court is required to interprete the words by looking at the difference in previous law.

The signaficance of mischief rule is that it makes the act work as parliament intented, but it can be argued that this destories the parliament supremacy. Anyway, this correct the mischief and avoid the absurd or unjust results, which are better than literal rule and golden rule.

d) Purposive Approach

The purposive approach looks for the intention of the parliament and of ministers. It is not only regard at the difference in previous law, but also allow for the judicial law making. In another word, both golden rule and the mischief rule are the applications of the purposive approach.

The only issue to this approach is how to determine the intentions of parliament and whether judges should refuse to follow the words of parliament. On the good side, this approach looks for the intention of the parliament and allows the judicial law making. However, people criticised about the usurpation of the legislative function.
