Checks and Balances & Separation of Powers

[resisting arrest with violence]

Hi. I wonder why anyone here hasn't created a list of all the instances any branch of the U.S. government has violated the checks and balances/separation of powers doctrine of the U.S. Constitution. Some examples readily come to mind like 2 Boland Amendments to prevent the Reaganites from continuing to fund the Contras (which the Reaganites ignored), the absence of Congress declaring war on Vietnam, Iraq, etc. It would be a useful list from an agitational point of view. A referential list would be helpful in countering the claims of the Federalist Papers that our system is excellent.
