India has approached Portugal's Supreme Court challenging its High Court order which had terminated the extradition of underworld don Abu Salem for breach of agreement by India by slapping charges which attract death penalty. India, in its appeal before the Portuguese Supreme Court, has said the interpretation of the High Court of the trial in various courts of the country was not correct.

Official sources said in New Delhi today that, in its affidavit, India has assured that the fresh charges levelled against Salem, a key accused in the 1993 Mumbai blasts case, attracted less jail term than the offences for which he had been extradited.

Sources said, that in its plea, India has asked for a stay on the Portuguese High Court order. The Lisbon High Court had on September 19 allowed the plea of the extradited gangster, being tried in eight criminal cases including the 1993 Mumbai serial blasts, that he be sent back to Portugal.
