I know that protocol and respect are important in these settings.
But if would have been beautiful if the attorney had responded, “Your honor, we are presenting oral arguments. The presentation of false information at this time, as you have just done, is a serious offense against this court. I challenge your facts. Can you provide evidence to substantiate the claims you have just made?”
I agree with that and her recusing herself. How can she rule intelligently on something on which she knows absolutely nothing, or worse what she does ‘know’ is so absolutely wrong? If what she said was true you might be prone to agreeing that something should be done, but it is not true and the fact she believes it to be lets us know how uniformed she is.
