Sanjay Dutt, who surrendered today before a special TADA court in Mumbai,  is planning to file a curative petition before the Supreme Court, his lawyer said today.

"We are planning to file a curative petition in the apex court soon," Dutt's advocate Rizwan Merchant told special TADA Judge G A Sanap when the proceedings were on to take the 53-year-old actor into custody.

Dutt had earlier filed a review petition in the apex court against its March 21 judgement upholding his conviction under the Arms Act and sentencing him to five years in jail.

The apex court had, however, rejected the review petition and directed him to surrender by May 16. After review petition, a convict is left with the option of filing a curative petition or a pardon petition.

The concept of curative petition was evolved in 2002 by a SC judgement to cure any defect that may lead to gross miscarriage of justice in a final judgement/order of the Supreme Court, after dismissal of a review petition.

While a review petition has to be filed within 30 days of the judgement, there is no time limit for filing a curative petition. Dutt's remaining options also include a leniency plea and remissions (like for good behaviour) which can reduce his jail term.
