New Delhi: The Supreme Court on Thursday questioned the Central Bureau of Investigations (CBI) for the delay in filing of appeal against the Allahabad HC verdict on dropping conspiracy charges against LK Advani and others in Babri case. The apex court also turned down the CBI's plea to file a fresh affidavit in the case.

The CBI took more than 90 days to appeal against the Allahabad high court order dated May 21, 2010 that upheld a special court's decision to drop conspiracy charges against senior BJP leader LK Advani and 19 others. This despite the CBI being given 90 days to file the appeal against the HC order.

The Supreme Court also pulled up the premier investigating agency for terming the Babri Masjid demolition as a national crime. "You can't say it is a national crime till we or trial court decides this way or the other," it said.

The Babri masjid case has been in the Supreme Court since 2011.
