The presidential team and its supporters would answer the question posed at the beginning as follows: good people holding high offices will do good things. However, history teaches us that the more power one obtains, the more reliable safeguards against possible abuse are needed. And personalities have nothing to do with that.
Lessons in judicial independence to be learned from the USA
In this context, it is worth learning a history lesson from the United States of America, for many reasons. However, the key ones are as follows: first, the US Attorney General is a member of the Office of the President of the United States. This is because the President of the United States is the head of the federal executive power and, in accordance with the Constitution, "ensures the correct enforcement of the laws" by the Department of Justice in particular; secondly, it is often the case that a close political ally of the president gets this position.In other words, the US Attorney General and the Department of Justice itself are part of the president's office. However, for nearly half a century, Congress has sought clarification on how every candidate for Attorney General will guarantee the Department's independence from the White House.
"These restrictions are a small price, and a necessary one, for restoring and maintaining public confidence in the Department of Justice ... [which] should be recognized by all citizens as a neutral zone in which neither favor nor pressure nor politics is permitted to influence the administration of the law."Other US Attorneys General also supported the course of their predecessor.
"It is imperative that there be public confidence that the laws of the United States are administered and enforced in an impartial manner," Attorney General Alberto Gonzalez said in 2006.In 2009, Attorney General Eric Holder added:
"The rule of law depends upon the evenhanded administration of justice. The legal judgments of the Department of Justice must be impartial and insulated from political influence. It is imperative that the Department's investigatory and prosecutorial powers be exercised free from partisan consideration. It is a fundamental duty of every employee of the Department to ensure that these principles are upheld in all of the Department's legal endeavors."Eric Holder also reminded prosecutors of the US Supreme Court's decision in Berger v. United States where the court emphasized that they are representatives "not of an ordinary party to a controversy, but of a sovereignty whose obligation to govern impartially is as compelling as its obligation to govern at all." It is important that a similar policy is approved at the office of the President of the United States. The Chief Legal Counsel to the President stated that
"these rules exist to ensure both an efficient execution of the Administration’s policies and the highest level of integrity with respect to civil or criminal enforcement proceedings handled by DOJ. In order to ensure that DOJ exercises its investigatory and prosecutorial functions free from the fact or appearance of improper political influence, these rules must be strictly followed."The existence of these policies is a testament to the fact that both US Presidents and Department of Justice senior officials are fully aware of the fact that the Department is endowed with serious powers that can be used to the detriment of political opponents, or vice versa, to protect political allies.
In fact, it was no accident that the Watergate scandal became the grain from which these policies later emerged. After all, President Nixon pressurized Attorney General Elliot Richardson to avoid being held accountable for illegally bugging his political opponents.
Nevertheless, most observers, and often prosecutors themselves, continue to refer to the Ukrainian prosecutor's office as a "presidential vertical structure."
This story leads to the conclusion that the office of the president, which was negotiating the exchange, actually intervened in the criminal proceedings without informing the prosecutor's office.
