Modernization relies on law as the means of transformation. In these great processes of transformation, day after day, many more demands for new legislation have been proposed as a reaction to different social, political, economic and environmental situations which seemingly develop independently or deliberately. Governments need effective laws to govern these transformation processes by which they achieve their political objectives and public policies. Such needs may originate from different sources such as different ministries, a commission of inquiry, politicians, pressure groups, or sometimes from donors.
