Any deadline for completion of ITR Processed status?

Dear Experts,

For me, the status of ITRs is

1) AY 2008-09 --- Return Uploaded (Last year, I received a demand notice and got it corrected through a CA. He informed me that it was a system error and there were thousands of similar cases)

2) AY 2012-13 --- ITR-V Received

3) AY 2013-14 --- ITR-V Received

Is there any deadline to the department to get it completely processed? For all these years, I have filed for tax-refunds!

For other years, it is "ITR Processed"

Please clarify.

Regards,

Harsha
