+++After new law is passed, no guarantee when it will be notified. A provision in Advocate Act was passed in 1967(about) and signed by President, till today not notified by Govt.

This amendment said that Advocates will have right to represent their clients before any tribunal or adjudicating authority.

As per my impression, this amendment was passed and signed by President in about 1967.

To bring this law into force, all Govt has to do is to issue a notification.

As per my impression, it is not done till today. (Just learned after posting this : It came into force from 13,June 2011 , Notified in 2011) 

Once a writ petition was filed in Court to direct Government to issue such notification. But petition was rejected by Court saying that Court cannot give such directions.
