The top 20 play a big role in this instance @ThePiedPiper. Litigation company will look at the make up and while your correct about who suffered losses at the time of what was announced, the litigation company will look at the time frame and who would still be holding to initiate any legal preceding.

Firstly they will tell you in that time frame around 20% would have sold and moved on. Then you have to take away NMDC holdings, which at the time would have been around 50% or more, and are not going to proceed in legal proceedings against the company,add to that, Sharon's holdings, who also won't take legal proceeding when she was the Managing Director at the time. Finally, you have a small percentage of around 20% share holders left and not all of them would have been impacted by the announcement at the time, so it would become a case of not viable for a litigation firm to take on.

It would be best for any individual to call a litigation company and ask if they have a case but the above would be what I think you will find to be the case after looking at the top 20 and who is holding.

No harm in making a call. Lessons can be learnt, that a tight register is not always a good thing for small share holders
