Okay, pick any famous LIVE attorney. It doesn't detract from my point.
The lawyer in question would have to agree to take your case before you have the right to be represented by him/her. Assuming that the lawyer is qualified [bar membership], that you have the $$$$ to afford it and that his/her schedule allows it [otherwise the lawyer would not take your case], once you retain that lawyer's services, you have that right - that's how I read Scalia's opinion.
