A Vakalatnama is that document that empowers a lawyer to act for and on behalf of his/her client. A Vakalatnama under which a lawyer is empowered to act may be general. It is a document that confers wide authority upon a lawyer.
A lawyer holding  a Vakalatnama can hardly come under the question of an authority of the case.
