The perjury or stay by high court on such petty issues are not maintainable, hence you may follow up the case through trial court itself properly.
As far a lawyer is concerned, the party to the litigation can engage the services of a lawyer and the lawyer cannot be engaged for the services ass well as a power of attorney of the party.
Therefore you may confirm if you have engaged the services of your lawyer by giving a vakalatnama in his name or had given him power of attorney deed to represent you before court. In the latter case your lawyer cannot plead ion your behalf, he can just remain as your representative, in the former, he can advocate your cause in the court and fight for you as your lawyer before the court.
