The World Justice Project published its Open Government Index 2015. In the overall score, Malaysia ended on a dismal 88th place out of 102 countries.
Malaysia scored well on "Publicized Laws and Government Data", but badly on "Right to Information", "Civic Participation" and "Complaint Mechanisms".
This kind of research always has a subjective element in it, but overall (from own experience) I would agree with the above findings: excellent laws, but what is the use of it when enforcement and transparency are so lacking.
I guess most people have similar experiences with a complaint to a government agency that ended in a drawer somewhere and never came out of it. The reason why many people don't even bother anymore to file a complaint.
