Of course, everyone has a different definition of what we call "that which shouldn't be done." But there is broad public consensus on some things like special privileges or improper lobbying, manipulating the law for personal gain (such as indeliberations on the rates for customs duties for imports), or conspiring to fix public bids, and so on.
當然所謂「不該做的」，每個人定義不同，但像特權關說、因私利而左右法案（例如進口關稅的稅率審查）、包攬工程等等，是比較公認的。
