As the fundamentals of law describe that courts are just to interpret the law and not to give their own definition but it is generally seen that the courts (even SC) interpret the law discretionary. Recently, the SC held that the cooling period of 6 months is mandatory in mutual divorce and can't be waived as it has been written in law and courts doesn't have any discretion.
Now coming to other points, the law has also written that the divorce case to be concluded in 6 months, Domestic Violence in 2 months, Criminal Trial as soon as possible, even then these trials take half of litigant's life.
Why doesn't the Courts interpret as these are written in law and pass suitable directions to the trial courts.
