Sir,

On Dt. 03/11/2007, Wife filed case under DV act 2005. While this was pending she again filed case under DV act 2005 at her maternal place on Dt. July 2010.

After giving (by the respondant) certified copies of first case in the second case, she withdraw second case.

she lost the first case (All her demands are rejected in judgement) on Dt. 17 January 2012

Now, she again (third time) filed case under DV act 2005 in different court on Dt. 02 may 2012.

Is it worth to go to High Court to file a case under "The Law of Vexatious Litigation"?

You can challenge it in the high court and ask for the quashing of DV Act, the act of her it self shows that she wants to harash you .

yes.go to highcourt for quash

Appears to be ideal case for quashing
