New Delhi, May 14 : The Supreme Court on Thursday will hear Bharatiya Janata Party (BJP) leader Varun Gandhi''s petition seeking quashing of the National Security Act (NSA) invoked against him.

The apex court will also hear the Uttar Pradesh Government petition, challenging the recent quashing of the NSA on Varun.

In its petition, the government has argued that the Advisory Board''s decision was incorrect, as it had ignored several cogent evidences against Varun.

The imposition of NSA on Varun by Mayawati Government has been termed invalid by the UP Advisory Board appointed by Allahabad High Court to go into the merits of the case.

Varun had submitted his representation before an Advisory Board in the Lucknow bench of the Allahabad High Court on April 28 against slapping of the NSA over his alleged hate speech in Pilibhit.

As the ultimate statutory authority on the NSA, the Advisory Board has the right to approve or revoke the government order invoking the act against Varun.

The verdict of the Advisory Board is final and if it chooses to revoke the NSA, Varun would be set free with immediate effect.

The Supreme Court on May 2 had extended the interim bail of Varun till May 14.

Varun was charged for making highly inflammatory anti-Muslim utterances during his poll campaign in Pilibhit. (ANI)
