If the case really involves question of law which has made grave injustice to the clients then he can move further in the case. I think we are all assisting to administer justice to general public . so we being a amicus curie in real sense should help people to get out of such unsatisfied conditions where they have a mind set that they wont get justice..
No it is not proper, but let the client declare beforre the court and do not declare it unless and until the client gives in writing and files papers before court. What is imoportant it is for the client to declare before the court. Now a days clients are very wise or say over wise and some time they involve for mis conduct. Better declare no instructions.
