How many more you want. I got plenty.
No they can't "pump out any law they want". As I clearly posted above, they are "clearly limited by statute and closely monitored by the General Assembly." This is common practice in all levels of government, state, local and Federal and has been so for centuries. That is quite a long time to keep paint on that cow. If statutes had to be written for every policy and regulation necessary for the operation of all government agencies that government would grind to a halt under the sheer number of items to be dealt with. It is unreasonable to expect legislators to be knowledgable on the interworkings of all the issues that every state or federal agency deals with to be able to write such legislation. Limited authority is delegated to the agencies and the knowledgable people running those agencies that are expert in that field under the watchful eye of the legislature.
wait you stated no elected official involved...now your stating legislative members are involved...wow now i see where the confusion started...
