After the Supreme Court dismissed petitions seeking independent probe into the death of special CBI judge Loya, the Congress has challenged the judgment and said that the verdict left many questions unanswered and that it marks a sad day in history. The Congress has reiterated its demand for a probe into Judge Loya's death. The SC had ruled that Loya died of natural causes and that the petitions were a serious attempt to scandalise and obstruct the course of justice.
