for implementing limitations to power in order to avoid its abuse.101 But, if this is the
purpose of impeachment, the very least that can be required of the body conducting it is
precisely that its implementation does not convert it into a weapon against the
constitutional State itself, which would occur if it was the Legislature that exceeded its
powers of prosecution and incurred in an abuse of power against those who it was
prosecuting. As one author has indicated, “the dangerous aspect of the matter is that
impeachment is very useful for carrying out dismissals in order to remove from the
chambers all the minority legislators who do not obey the orders of the majority group or
alliance. But also, owing to the way in which it is conceived, it leaves in the hands of those
who have a sufficient majority in the legislative organs the possibility of easily annulling the
other public organs, bringing them to a halt, dominating them and, finally, ending their
independence”102 (italics added).

Although the organ with competence to hear and decide an impeachment proceeding
is a political organ (in those countries where the Legislature has this power), the whole
process must be conducted with legal meticulousness, in accordance with the provisions of
the Constitution, and the legal norms that regulate it,103 as well as with the relevant
standards established in the Convention. Impeachment involves a trial similar to a judicial
proceeding, in the sense that the legislative chamber that is conducting the hearing in some
way becomes a professional judge. It involves legal control insofar as it is regulated by law,
and also jurisdictional control because it cannot be understood to be exempt of the formal
and substantial element of due process. Thus, González Oropeza had defined impeachment
as the “proceeding to establish the individual or official responsibility of a public servant
[that] entails the practical exercise of a jurisdictional function by an organ with political
functions, but respecting the essential formalities of a jurisdictional proceeding.” 104

Consequently, in reality, impeachment involves mixed control: “political control”
only as regards the institutional status of the organ conducting it, the offenses and the
sanctions to be imposed; “legal control” because the monitoring action is subject to the
law, and it is jurisdictional as regards the nature of the function and the human rights of
due process of those who are tried. If those who are put on trial are members of the State’s
Judiciary – or of any of the high jurisdictional organs – there are also other significant
elements to consider, such as the principles of the separation of powers and, as I have
expounded above, the institutional aspect of the independence of judges, which entail
important practical consequences.

Indeed, it is only by acknowledging the “jurisdictional nature” of the function of
Congress in relation to impeachment that it is possible to ensure judicial independence. 105
Hence, if we wish to protect judicial independence we must consider that impeachment is
an exceptional means to remove judges, and not a mechanism at the service of the
parliamentary majorities to try and control the Judiciary. In other words, if it is understood

On this point expert witness Despouy indicated that, in an impeachment proceeding, “the guarantees of
due process of law” must be respected and “especially, in the case of judges of the Supreme Courts of Justice and
also, as in this case, the members of the Constitutional Tribunal” (Statement during the public hearing on March
18, 2013).
