Legislation should be prepared and implemented with care. This is known as “legislation quality” and although given lip service in many countries, including NZ, it is more honoured in the breach! For example Attorney General reports noting that legislation breaches basic human rights, but it is passed anyway, under urgency. Fools rush in, where angels fear to tread.
It is difficult to communicate why this is so, as most people expect legislation to work fully with desirable effects and have no adverse outcomes at all. Especially in the social sphere, it isn’t that simple. Maybe an analogy with introducing new drugs will illustrate these types of issues?
Drugs are meant to be tested for efficacy before being introduced. Then they are meant to be carefully monitored for adverse outcomes.
Similarly, the efficacy of new legislation needs to be checked before passing into law. After passing into law, it also needs to be monitored for adverse outcomes, with the same care as drugs. If this is not done, then problems that could have been stopped while they are small, progress on to be unnecessarily huge problems. Again, this concept is called “legislation quality”.
In the same way that this concept may be taken from medicine to law, disastrous examples can also be taken from medicine to law.
