The Delhi High Court on Monday sought response of Christian Michel and the CBI on plea of Tihar Jail authorities challenging a local court order allowing him to make international phone calls in violation of prison rules.

The jail authorities in its plea alleged that no facts and circumstances were considered by the local court for granting an “illegal and improper privilege of communication”.

In January, the local court had allowed Michel, arrested in the AgustaWestland VVIP chopper case, to make international phone calls to his family, friends and lawyers. He was granted 15 minutes a week for making the calls.

The jail authorities said the prison manual provided only for 10 minutes per week for making calls. It said as per the January 27, 2017, circular of prison authorities, a foreign national is only allowed to make calls to the country of his or her origin.

Michel’s country of origin is the U.K. and as per the jail call records, he has been mostly contacting his “legal representative” in Italy.

The high court has posted the case for further hearing on April 22. It said Michel be produced before the court on the next date, if already not released from jail.

Michel was extradited from Dubai and later arrested by the Enforcement Directorate in December last year. He was later arrested by CBI in a case related to ₹3,600-crore AgustaWestland deal
