Service Tax query

Hi everyone,

Can anyone give me a proper solution on the same.

As Our company is paying Commercial rent on various properties hired & taking input credit of service tax on the same from last 2 years. Now, as per ruling of Delhi High court, the same is ultra virus to the Law.

So, now i need to know:

1. How can i take my money back, as service tax paid?

2. Will i have to reverse my service tax input credit of the same?

3. will i have to revised my returns for last 2 years?

Plz reply urgently, if u can..................:)
