Excess canvat refund of service tax

CA Adarsh Madrecha (Chartered Accountant) (200 Points)

21 June 2014  
A partnership firm takes services from a person. Pays service tax on the service received. Provided only taxable service, but amount payable is less than the service tax paid on services received (that is, cenvat credit is excess ) Can we claim refund of this excess cenvat? Is there any time limit to carry forward this if refund is not available?
