In diet pills without a prescription a small law firm, one attorney in charge the case should be the party to the within action. How about those assistants? or other attorneys?

"The party to the within action" is NOT the attorney or his/her assistants. It is the person who is suing or the person who is being sued. In other words, the people who are paying the lawyers are the "parties" in a lawsuit (action).
Never heard the expression!
The phrase has nothing to do with the lawyer or the law firm.
It has to do with the parties to the lawsuit that the documents are talking about.
