Just in: The Supreme Court turns down the Talwar couple's plea for reports of a polygraph, brain mapping and narco-analysis tests of their three domestic helps who were the initial accused in the murder of their daughter Aarushi. The court said these were simply delaying tactics.

The court reserved the order after the accused couple, who are facing trial for allegedly killing their teenaged daughter, pleaded these reports are essential to defend themselves and CBI is opposing their plea saying that it is a tactic on the part of the couple to prolong the trial.

The Talwars had approached the top court challenging the order of the trial court and the Allahabad High Court dismissing their plea for a direction to the agency to produce the reports of tests carried out on Raj Kumar, Vijay Mandal and Krishna in the trial court.

Pleading for scientific records to be taken on record by the trial court, senior advocate UU Lalit, appearing for the Talwars, submitted such tests were conducted on the couple which extinguished any possibility of their involvement in the crime but the tests done on their servants suggested the possibility of their involvement.
