Jodhpur:  The Rajasthan High Court on Monday stayed the permission of a lower court to conduct a voice-test on Sohan Lal Bishnoi to verify the authenticity of some audio clips related to missing nurse Bhanwari Devi.

The clips have voices of Sohan Lal and Shahbuddin, both currenly under judicial custody, among others and the CBI wanted to verify its authenticity.

The Magistrate Kailash Chandra Joshi issued the direction on application of Bishnoi, currently under judicial custody, challenging the CBI court's approval to conduct the test.

The court on a request by CBI last week had given permission to the agency to conduct the test to match the voices of Sohan Lal and Shahbuddin with those in the audio clips.

The CBI wants to find out the authenticity of these voices in the clips, specially of Shahabuddin and Sohan Lal Bishnoi, but the counsels of both had objected to this request terming it as violation of the Constitution and denial of the right to silence.

On Monday, the counsel for the Sohan Lal moved application in the High Court against the approval by the lower court, following which the high court gave directions.
