I'm still waiting.
No mention of an attorney working off another attorney's license.
That's not what she did. She worked in association with someone who had a valid license in the state, which is permissible under Rule 5.5(c)(1).
But, that was your claim. That a person could work under another persons license. You didn't specify in which court or whether state, local or federal.
Rule 5.5 of the Massachusetts Rules of Professional Conduct states that an attorney
cannot, without a license to practice in Massachusetts,
establish an office or other systematic and continuous presence in this jurisdiction for the practice of law. It also states an attorney
cannot, without a license,
hold out to the public or otherwise represent that the lawyer is admitted to practice law in this jurisdiction.
