• Refund of tax on cancelled invoice

We have raised the sales invoice but till the date of 44 ab finalisation we dont know that the sales invoices were cancelled. but we have remitted the taxes on cancelled invoices.we have no option to revise the vat returns to rectify the mistake.
But we filed income tax returns after considering the cancelled invoice. vat annual returns was also filed after considering cancelled invoice. my purchaser is also not claimed any input on this invoice. it is from karnataka valued added tax act.

My querry is that can we claim refund of the output tax paid on the cancelled invoice. is yes please quote the case laws
