The one thing that stands out in most of these writings and pronouncements is that they refer to interference with the judiciary as an institution. They address interference with the judiciary by the two other institutions in the trias politicas (the three arms of government), namely the executive and the legislature. One will rarely come across works, either academic or judicial, dealing with interference within the judiciary itself, that is to say, where one judicial officer seeks to interfere with the exercise of the judicial discretion or work of another.
I would venture to say that this rarity exists because judicial officers are mostly (certainly not always) persons of high moral and ethical integrity. One would suppose that they would not even contemplate improperly influencing one another, presumably because they appreciate the importance of a judicial officer doing the correct thing under the circumstances of a particular case, whose peculiar circumstances may not readily be appreciated by another judicial officer.
