CORRUPTION OF FACE-VALUE: Anybody who has been to court knows that a "bada vakil" can do what a "chhota vakil" cannot i.e. favourably influence judges and cow down opposing lawyers of lesser stature.
As humans, we are awestruck and bedazzled by those with who are more wealthy. Judges, being human, put senior counsels on a pedestal, and treat relatively junior lawyers like dirt.
So, if you can only afford to engage an ordinary lawyer, while the other side has engaged Jethmalani, Singhvi, Jaitley etc, then God help you!
