Justice Indermeet Kaur stayed the trial court's order which had on October 31 allowed conduct of the test on the 63-year-old top Maoist leader.

The court passed the order after Ghandy's counsel Rebecca M John submitted that until and unless Constitutional validity of narco test is decided by the Supreme Court, an accused cannot be forced to undergo such a test.

She submitted that the Supreme Court has been consistently denying such a test on accused in view of the pending case before it in which a Constitution bench has reserved its order.

The High Court also issued notice to the police and directed it to file a status report by December 14.

Ghandy approached the High Court contending that he cannot be forced to give evidence against himself as it violates his right under Article 20(3) of the Constitution and he had not given any consent for the test.

The trial court had on October 31 allowed the police to conduct narco test on Ghandy, arrested from the national capital on September 20, after the probe agency contended that it had not been able to elicit all information from him despite use of all scientific methods of interrogation.

The trial court had passed the order after going through the medical report submitted by AIIMS which said Ghandy was medically fit to undergo the test.

Challenging the order, Ghandy said the validity of such an invasive test is still not clear as the matter is pending before the Constitutional bench of the Supreme Court which has reserved its order on the issue.

Ghandy, who has been booked under various provisions of Unlawful Activities (Prevention) Act, submitted that the magistrate should have waited for the Supreme Court judgement.
