Wrong pan in itr

In my view Department will suceed as mentioning of wrong pan attracts penalty as leived by them.

However click on the site for finding any case law in your favour :

I think even if court battle is fought, Income Tax department will succeed saying "we always recommend to read instructions, rules and procedures of filing tax returns". And they will claim it is clearly mentioned and assumed tax payer read that a penalty will be levied for wrong PAN entry.
