Is it common, considered a good tactic, or even allowed, to move a court to censure – or even hold in contempt – the opposing counsel?
If one has a reasonable argument for why the opposing counsel is out of line, and the judge hasn't called them on it, it seems to me like it would almost always be a good tactic. And it seems like it could occur with some frequency when the opposing counsel is a criminal prosecutor, since their duty is to truth and justice, and it's a fine line to walk between being a principled advocate for justice and a competent adversary to a defendant.
But what is the reality? Are such motions allowed? Do judges take kindly to being encouraged to censure an officer of their court? Are there clear benefits or expected outcomes of such motions?
Also, would such motions succeed by appealing to the principles espoused by courts and legal professional associations? Or does a lawyer really have to substantially neglect their duty or abuse their position before a motion to censure will be entertained?
